Simulation of Flow, Sediment Transport, and Sediment 

Mobility of the Lower Coeur d’Alene River, Idaho

By Charles Berenbrock and Andrew W. Tranmer

Abstract

A one-dimensional sediment-transport model and a 

multi-dimensional hydraulic and bed shear stress model 

were developed to investigate the hydraulic, sediment 

transport, and sediment mobility characteristics of the lower 

Coeur d’Alene River in northern Idaho. This report documents 

the development and calibration of those models, as well as 

the results of model simulations. 

The one-dimensional sediment-transport model 

(HEC-6) was developed, calibrated, and used to simulate 

flow hydraulics and erosion, deposition, and transport of 

sediment in the lower Coeur d’Alene River. The HEC-6 

modeled reach, comprised of 234 cross sections, extends 

from Enaville, Idaho, on the North Fork of the Coeur d’Alene 

River and near Pinehurst, Idaho, on the South Fork of the 

river to near Harrison, Idaho, on the main stem of the river. 

Bed-sediment samples collected by previous investigators 

and samples collected for this study in 2005 were used 

in the model. Sediment discharge curves from a previous 

study were updated using suspended-sediment samples 

collected at three sites since April 2000. The HEC-6 was 

calibrated using river discharge and water-surface elevations 

measured at five U.S. Geological Survey gaging stations. The 

calibrated HEC-6 model allowed simulation of management 

alternatives to assess erosion and deposition from proposed 

dredging of contaminated streambed sediments in the Dudley 

reach. Four management alternatives were simulated with 

HEC-6. Before the start of simulation for these alternatives, 

seven cross sections in the reach near Dudley, Idaho, were 

deepened 20 feet—removing about 296,000 cubic yards of 

sediments—to simulate dredging. 

Management alternative 1 simulated stage-discharge 

conditions from 2000, and alternative 2 simulated conditions 

from 1997. Results from alternatives 1 and 2 indicated that 

about 6,500 and 12,300 cubic yards, respectively, were 

deposited in the dredged reach. These figures represent 2 

and 4 percent, respectively, of the total volume of dredged 

sediments removed before the start of simulation. 

In alternatives 3 and 4, the incoming total sediment 

discharges from the South Fork of the river were decreased by 

one-half. Management alternative 3 simulated stage-discharge 

conditions from 2000, and alternative 4 simulated conditions 

from 1997. Reducing incoming sediment discharge from the 

South Fork did not affect the streambed and deposition in 

the Dudley and downstream reaches, probably because the 

distance between the South Fork and the Dudley reach is long 

enough for sediment supply, transport capacity, and channel 

geometry to be balanced before reaching the Dudley and 

downstream reaches.

Development and calibration of a multi-dimensional 

hydraulic and bed shear stress model (FASTMECH) allowed 

simulation of water-surface elevation, depth, velocity, bed 

shear stress, and sediment mobility in the Dudley reach 

(5.3 miles). The computational grid incorporated bathymetric 

and Light Detection and Ranging (LIDAR) data, with a node 

spacing of about 2.5 meters.

With the exception of the fourth FASTMECH calibration 

simulation, results from the FASTMECH calibration 

simulations indicated that flow depths, flow velocities, and bed 

shear stresses increased as river discharge increased. Watersurface elevations in the fourth calibration simulation were 

about 2 feet higher than those in the other simulations because 

high lake levels in Coeur d’Alene Lake caused backwater 

conditions. Average simulated velocities along the thalweg 

ranged from about 3 to 5.3 feet per second, and maximum 

simulated velocities ranged from 3.9 to 7 feet per second. 

In the dredged reach, average simulated velocity along the 

thalweg ranged from 3.5 to 6 feet per second. The model also 

simulated several back-eddies (flow reversal); the largest eddy 

encompassed about one-third of the river width. Average bed 

shear stresses increased more than 200 percent from the first 

to the last simulation. Simulated sediment mobility, assessed 

using bed shear stress, showed substantial transport of very 

coarse sand to fine gravel in these simulations. Areas of 

greater sediment mobility occurred near the thalweg, and areas 

of lesser mobility occurred near the banks and back-eddies.
2 Simulation of Flow, Sediment, Transport, and Sediment Mobility of the Lower Coeur d’Alene River, Idaho

Introduction

The Coeur d’Alene River flows in a westerly direction 

from its headwaters in the mountainous, coniferous forests 

near the Idaho-Montana border to its outlet in Coeur d’Alene 

Lake (fig. 1). The North Fork (NF) and South Fork (SF) 

Coeur d’Alene Rivers converge downstream of the town of 

Enaville, Idaho. From there, the main stem Coeur d’Alene 

River flows about 35 mi westward where it empties into 

Coeur d’Alene Lake. The Coeur d’Alene River terminates at 

the inlet to the lake; the lake’s outlet is on its north end and 

forms the beginning of the Spokane River. The Post Falls 

Dam is about 9 mi downstream of the lake (fig. 1). The dam 

regulates the Coeur d’Alene Lake water level from mid-June 

to mid-November. The Spokane River continues flowing 

westerly through Idaho and part of Washington, passing 

through several dams before joining the Columbia River at 

Franklin D. Roosevelt Lake (fig. 1).

More than 100 years of mining in the upper 

Coeur d’Alene River basin have resulted in the transport and 

deposition of large quantities of metal-enriched sediments into 

the lower Coeur d’Alene River and onto its floodplain. The SF 

Coeur d’Alene River flows through the Coeur d’Alene Mining 

District, one of the world’s largest producers of silver and 

one of the Nation’s largest producers of lead and zinc (Long, 

1998). Mining produced more than 130 million tons of leadzinc-silver sulfide ores from the district since the mid-1880s 

(Long, 1998). From the 1880s to 1968, mine waste (tailings) 

was dumped into the river (Ellis, 1940). The river carried the 

tailings downstream, especially during moderate to high flows, 

and deposited them in the lower reaches. Previous studies 

have shown that the highest concentrations of contaminated 

sediments are in the streambed. The sediments are entrained 

and redistributed during high-flow events (Bookstrom and 

others, 1999; Box and others, 2001; Box and others, 2005). 

Some of the highest concentrations of lead in the streambed 

were detected in the reach near Dudley, Idaho (Bookstrom 

and others, 2004). During times of flooding, metal-enriched 

sediments are deposited and (or) remobilized in the flat 

lower Coeur d’Alene River valley (Cataldo to Harrison) and 

its floodplain. The flood history of the lower valley—1933, 

1949, 1956, 1964, 1974, 1995, 1966, and 1996 (Woods and 

Beckwith, 1997; and Box and others, 2005)—includes the 

most recent large peak flow, which occurred in 1996.

 The Coeur d’Alene River flows naturally because 

no dams or major diversion structures lie upstream of 

Coeur d’Alene Lake. Eleven peak flows greater than 

30,000 ft3/s occurred before 2005, as measured at the U.S. 

Geological Survey (USGS) Coeur d’Alene River near 

Cataldo gaging station (12413500). The largest peak flow 

(79,000 ft3/s) was measured on January 16, 1974. A peak flow 

of 70,000 ft3/s was measured during the most recent large 

flood on February 9, 1996 (Brennan and others, 2006; updated 

from Beckwith and Berenbrock, 1996). Average spring runoff 

for the period of record is about 15,000 ft3/s, and summer 

discharges usually are less than 600 ft3/s. The annual mean 

discharge for the period of record is about 2,500 ft3/s. Without 

flood control structures in the channel, periodic flooding of 

the lower valley occurred naturally during high flow events. 

This led to the construction of levees in flood prone areas 

to protect resources, the railroad, and nearby communities. 

These levees, especially in the lower valley, have limited the 

lateral movement of the river. River discharges must exceed 

20,000 ft3/s to overtop levees and overflow riverbanks.

The Post Falls Dam creates a backwater effect in the 

Coeur d’Alene River that reaches upstream to Mission Flats 

(fig. 2). This backwater effect, in turn, decreases the river’s 

energy gradient and flow velocity, which affects erosion and 

sediment transport processes. Sediments move downstream 

from upper reaches of the basin to the lower energy gradient 

reaches of the lower Coeur d’Alene River valley. Decreased 

velocities in the lower valley limit the river’s ability to 

meander and change course, and decrease the transport of 

sediments. For floods at bankfull and less, sediment transport 

takes place only in the river. Sediments are mobilized and 

transported downstream in the streambed. When the river 

banks are overtopped, sediments in the river and the floodplain 

remobilize and move downstream.

Sediment transport is a physical process that depends on 

many hydraulic factors in the river and surrounding areas. The 

Coeur d’Alene River transports sediments and unconsolidated 

material from the streambed, banks and floodplain. Upstream 

of river mile (RM) 159.8 near Mission Flats, the streambed 

is composed mostly of gravels and cobbles. Downstream of 

RM 159.8, the composition is mostly sands and silts. These 

sediments vary in their degree of mobility. 

The USGS, in cooperation with the Idaho Department of 

Environmental Quality, Basin Environmental Improvement 

Commission, and the U.S. Environmental Protection Agency 

developed flow hydraulic and sediment-transport models of 

the Coeur d’Alene River between Enaville and Pinehurst, 

Idaho to Coeur d’Alene Lake near Harrison, Idaho. These 

models will help improve the understanding of streamflow, 

hydraulics, bed shear stress, erosion and deposition, and 

sediment-transport processes. The models also will provide 

insight into the effects of proposed recovery actions in the 

river. 

One model, a one-dimensional (1D) sediment-transport 

model, encompasses the reach beginning upstream at the 

streamflow-gaging stations on the NF Coeur d’Alene River 

at Enaville (12413000) and the SF Coeur d’Alene River near 

Pinehurst (12413470) and ending at the gaging station on the 

Coeur d’Alene River near Harrison (12413860) near the inlet 

to the lake. This model incorporated 234 cross sections, about 

1,000 ft apart, in the reaches downstream of Mission Flats 

(fig. 2) and at variable intervals (200–2,000 ft) upstream to the 

Enaville and Pinehurst gaging stations.

Introduction 5

The USGS also developed a multi-dimensional hydraulic 

and bed shear stress model for a smaller reach in the lower 

valley near Dudley. This model was used to simulate flow 

hydraulics and sediment mobility potential based on shear 

stress and bedform geometry in the lower Coeur d’Alene 

River. The study reach contains highly contaminated 

streambed sediments; part of the streambed in this reach 

may be removed by dredging because of the contaminated 

sediments (Bookstrom and others, 2004).

Purpose and Scope

This report documents the development and 

calibration of a 1D sediment-transport model and a multidimensional hydraulic and bed shear stress model of the 

lower Coeur d’Alene River. The study reach (figs. 1 and 2) 

encompasses the lower Coeur d’Alene River from Enaville and 

Pinehurst to about Coeur d’Alene Lake, with a detailed focus 

in the Dudley reach near Rose Lake (fig. 2). Understanding the 

hydraulic and sediment-transport characteristics of the Dudley 

reach is of primary interest because of proposed dredging to 

remove contaminated streambed sediments (Bookstrom and 

others, 2004).

The scope of this report (1) defines flow types, river 

stages, river discharge, channel geometry, streambed 

sediments, and total sediment load; (2) documents the 

development and calibration of models of the study reach; and 

(3) examines the use of these models to simulate the response 

of the hydraulic and sediment system to river discharges, lake 

levels, and sediment input scenarios. The model simulation 

results can help facilitate the evaluation of the feasibility and 

potential effects of remedial actions (management alternatives) 

on the streambed. 

The 1D sediment-transport model used in this study 

simulates a movable streambed, in contrast to many models 

in which the streambed is fixed and does not change. This 

1D sediment-transport model averages parameters across the 

cross sections and calculates erosion, deposition, and sediment 

transport. One-dimensional models usually require less 

setup, run-time, and data than two-dimensional (2D) models. 

However, 2D models are able to simulate uneven water surface 

elevations, varying velocities, and flows in more than one 

direction in a cross section. For example, a 2D model that 

incorporated sediment transport was used to describe erosion 

and deposition of the Kootenai River in Idaho and the Platt 

River in Colorado (McDonald and others, 2006; Nelson and 

others, 2006).

Description of Study Reach

The Coeur d’Alene River originates in the upper part 

of the Coeur d’Alene and St. Joe Mountains near the IdahoMontana border and flows westward into Coeur d’Alene Lake 

(fig. 1). The river basin drains an area of about 1,475 mi2 and 

consists of two main branches of the Coeur d’Alene River, 

the North Fork (NF) and the South Fork (SF). These branches 

converge at RM 167.7 and then follow a sinuous path to 

the lake. The river crosses through Shoshone and Kootenai 

Counties, passing a few old mining and logging towns along 

the way. The study reach is about 35 mi long—starting 

upstream of Enaville on the NF and downstream of Pinehurst 

on the SF to Springston to about 1.5 mi upstream from the 

inlet to Coeur d’Alene Lake (fig. 2).

The Coeur d’Alene Mountains, at the headwaters of 

the river, reach elevations of 6,650 ft. The lowest point in 

the study area (2,128.8 ft at normal summer levels) is at the 

Coeur d’Alene River inlet to the lake, (NAVD 88 datum; 

Avista Corporation, 2005, p. B-2). The St. Joe Mountains near 

Cataldo reach elevations of 6,400 ft. These mountains are part 

of the Bitterroot Range, and consist of high forested peaks and 

steep intermontane valleys that cut through thick deposits of 

volcanic ash and metasedimentary rock. The study area is in 

the Coeur d’Alene metasedimentary zone (McGrath, 2002). 

Fractured quartzite and argillaceous rocks of Precambrian 

age underlie the study area (McGrath, 2002). Alluvium of 

Holocene and Pleistocene fills the valley and consists of 

unconsolidated fluvial and lacustrine deposits. The percentage 

of lacustrine deposits (silts and clays) increases toward the 

lake.

Vegetation changes with elevation. Only northern climate 

flora exists in the riparian zones. The valley areas consist 

of agricultural and open range land, wetlands, and lakes. 

Tree density in the valley becomes sparse with grasses and 

scrub vegetation dominating, especially in and around the 

wetlands and lateral lakes. Tree species include conifers, 

cottonwoods, willow, aspen, and birch. The lateral lakes 

feature a large variety of aquatic plants that provide habitat 

for avian and amphibious species. Around the turn of the 20th 

century, modification of natural levees formed by the river 

altered the hydrologic regime, and the reclaimed wetlands 

allowed for expansion of farming and cattle operations in the 

valley. At higher elevations, the study area primarily consists 

of coniferous forest comprised of Douglas fir, white pine, 

grand fir, western red cedar, and western hemlock. Mountain 

hemlock, subalpine fir, Engelmann spruce, and white bark 

pine dominate farther up the mountains. 

The river is unrestricted by any dam or flood control 

structures upstream of Coeur d’Alene Lake and is subject to 

seasonal and peak flows. The annual historical mean flow 

for the main stem of the Coeur d’Alene River near Cataldo 

(RM 162.9) is about 2,500 ft3

/s. Precipitation in the basin 

is highly variable due to orographic effects in the upper 

reaches—annual averages range between 26 and 40 in. of rain 

and 50 to 70 in. of snow. High flows in the winter can occur 

when heavy, warm rains from the Pacific Ocean rapidly melt 

the snowpack in the basin. The rapid snowmelt and heavy 

rains abruptly increase runoff from low winter base flows to 

high flows as during the winter high flows of 1995, 1996, and 

1997 (Box and others, 2005). In contrast, gradual melting of 
6 Simulation of Flow, Sediment, Transport, and Sediment Mobility of the Lower Coeur d’Alene River, Idaho

snow in the basin causes a slow rising and falling runoff curve 

(hydrograph) for spring, represented by flows from April 

through June 1997 (Box and others, 2005). Warm days and 

spring rainstorms cause small sharp peaks on the hydrograph, 

represented by flows from April through June 2006.

Interstate Highway 90 lies to the north and to some extent 

is parallel to the river until it reaches Cataldo where it follows 

the SF eastward toward Wallace. The Union Pacific Railroad, 

recently converted to a bicycle trail in the “Rails to Trails” 

Program, borders the river. Elevation of the bicycle trail 

usually is above the floodplain and acts like a levee restricting 

flooding.

The floodplain starts at the confluence of the NF and 

SF near Enaville and extends to Coeur d’Alene Lake. The 

floodplain width varies with the local topography and ranges 

from about 1,000 ft at the confluence of the NF and SF 

(RM 167.7) to more than 3 mi near Dudley and Rose Lake. 

From Dudley, the floodplain narrows to about 1 mi near Lane, 

then widens to about 2 mi near Medimont, and narrows again 

at State Highway 97 to about 1 mi (fig. 2).

Downstream of Cataldo, wetlands and lateral lakes border 

the Coeur d’Alene River (fig. 2). Eleven lakes and numerous 

adjoining wetlands are in the floodplain. These areas provide 

habitat for various aquatic and terrestrial species including 

zooplankton, amphibians, fish, muskrats, and beavers, as well 

as local and migratory fowl. Based on average depth, two of 

the lateral lakes (Black and Blue) are deeper than 20 ft, and 

six lakes (Anderson, Thompson, Swan, Killarney, Rose, and 

Porter) are between 10 and 20 ft deep. Three lakes (Cave, 

Medicine, and Bull Run) are less than 10 ft deep (U.S. Fish 

and Wildlife Service, written commun., 2006). Most wetlands 

have depths of 5 ft or less. Inundation of the floodplain occurs 

at varying discharges due to lateral lake and wetland expansion 

as well as overtopping of the levee system. Lateral lakes with 

connecting inlet channels provide hydraulic connectivity with 

the river. The wetlands and lateral lakes also act as terminal or 

semi-terminal sinks for the contaminated sediments. 

The levee system extends from the town of Cataldo 

downstream to the outlet at Coeur d’Alene Lake, with an 

average height of 7.5 ft. The original levees formed naturally 

from sediment deposition during floods when the river flowed 

out of its banks. These natural levees were highest near 

Cataldo and decreased in height in the downstream direction. 

The levee system changed as the valley population increased 

and land use changed. Many levees were artificially raised 

during the early 1900s to reclaim land for agriculture and 

cattle grazing. The Union Pacific Railroad Company also 

enhanced the levees along the southern edge of the river 

to support a rail line to the mining camps and mills. These 

levees constrained the river’s natural meandering course and 

stabilized the once dynamic riparian ecosystem.

Two major geomorphic reaches were identified in 

the study reach: a braided reach and a meandering reach 

(Bookstrom and others, 1999; Box and others, 2005). The 

braided reach includes the SF and NF and the main stem 

to RM 159.8 near Mission Flats (fig. 2). In the study area, 

the braided reach is about 11 mi long, and the river usually 

consists of multiple channels. Composition of the streambed 

is mostly gravels and cobbles. Gravel bars and terraces also 

are present along this reach. Considerable quantities of fines 

(clay, silt, and sand) also may be present in the SF and in the 

main stem because of poor mine-waste practices in the upper 

SF basin. Overall, the braided reach is a gravelbed river with 

median particle sizes (d50) ranging from 54 mm on the NF, 

19 mm on the SF, and 23 mm on the main stem (Borden and 

others, 2004). The surface layer of the streambed between 

Latour Creek (RM 160.340) and RM 159.8 (end of the braided 

reach) has a pavement of overlapping cobbles. Upstream of 

Latour Creek, the armored surface layer has mixed amounts 

of sands, gravels, cobbles, and boulders. The NF produces 

natural quantities of sediment from a relatively pristine 

upper basin. However, the SF produces excessive quantities 

of metal-contaminated fines—lead, zinc, silver, antimony, 

arsenic, cadmium, and copper (Woods and Beckwith, 1997; 

Bookstrom and others, 1999; and Bookstrom and others, 2001; 

Woods, 2001). Mean annual discharge from the NF (about 

1,900 ft3

/s) is about 4 times greater than from the SF (about 

510 ft3/s) (Brennan and others, 2006). Whereas, total sediment 

load from the SF is about 20 times greater than from the NF 

(Clark and Woods, 2001). Average flow depths in the braided 

reach usually are less than 10 ft, and water-surface slope is 

about 6.5 × 10-4 ft/ft.

The meander reach of the Coeur d’Alene River is a 

single channel with gentle bends, although the bends at RM 

135.25 and from RM 149 to 152 are sharp. The meander reach 

covers the main stem from RM 159.8 at Mission Flats to the 

Coeur d’Alene River inlet (RM 131) to the lake, a distance of 

about 29 mi. This reach cuts through a nearly flat floodplain, 

and channel widths vary between 200 and 350 ft. This reach is 

relatively stable due to the river location, levees, and railroad 

embankments that limits the lateral migration of the river. The 

streambed consists primarily of silts and sands (Bookstrom 

and others, 1999), and d50 ranges from 0.25 to 0.10 mm. Over 

time, these fine, heavy metal-contaminated sediments from 

mine tailings settled in the meander reach. Contaminated 

sediments were detected to a depth of about 10 ft below the 

river bottom and in meander point bars (Box and others, 2001; 

Bookstrom and others, 2004). Flow velocities are low in this 

reach because of backwater conditions. Average flow depths 

in the meander reach usually are 20 ft, and water-surface slope 

is about 6.5 × 10-5 ft/ft, about 10 times flatter than the braided 

reach.

River near Pinehurst (12413470). The Cataldo gaging station 
Previous Investigations 7

has been in continuous operation since 1920; Enaville since 

1939, Pinehurst since 1987, and Harrison since 1991. The 

Rose Lake gaging station was in operation from 1994 to 

2000. Only stage data are available at the Harrison and Rose 

Lake gaging stations because of backwater conditions at the 

sites. Discharge is not a function of stage alone in backwater 

conditions. A 1D hydraulic-flow model (Woods and Beckwith, 

1997) based on water-surface elevation data for the Harrison 

gaging station and discharge data for the Cataldo gaging 

station was used to estimate discharge at the Harrison gaging 

station. An acoustic Doppler velocity meter (ADVM) was 

installed at the Harrison gaging station on February 25, 2004. 

A velocity-stage-discharge relation has been used since 

March 2004 to determine discharge. Morlock and others 

(2002) provide a more complete discussion on computing 

discharge at sites using ADVMs. Discharges for the Cataldo, 

Enaville, and Pinehurst gaging stations are calculated by a 

stage-discharge relation.

Previous Investigations

 Since 1981, four surface-water models have been 

developed for the Coeur d’Alene River from Enaville 

and Pinehurst to the lake near Harrison. Each model was 

developed for a unique purpose; therefore, each poses its own 

drawbacks and limitations. 

FEMA Model (1981)

In 1981, the Federal Emergency Management Agency 

(FEMA) completed the first model of the lower Coeur d’Alene 

River for a flood insurance study (Federal Emergency 

Management Agency, 1979, and 1982). This model delineated 

the 100-year floodplain. The 100-year flood has a 1 percent 

chance of occurring in a given year. Discharge for the 

100-year flood is 69,000 ft3/s at the Cataldo gaging station 

(12413500) (updated from Berenbrock [2002] through 2007 

[n = 76]). For the area between Coeur d’Alene Lake and 

Interstate Highway 90, elevations and delineation for the 

100-year flood were based on high-water marks from the 1974 

flood and from USGS topographic maps (1:24,000 scale) 

(Federal Emergency Management Agency, 1979, 1982). Field 

surveys and aerial photographs from near Interstate Highway 

90 and upstream were used to develop a HEC-2 model and 

obtain cross sections. Bridges in the study reach also were 

surveyed. The FEMA model was calibrated using the highwater marks from the 1974 flood and other floods. Manning’s 

n roughness coefficients ranged from 0.025 to 0.035 for the 

main channel and 0.030 to 0.045 for the floodplain (Federal 

Emergency Management Agency, 1979, 1982). For the NF 

reach, coefficients of 0.040 were used for the main channel 

and ranged from 0.075 to 0.090 for the floodplain. For the SF 

reach, coefficients ranged from 0.035 to 0.065 for the main 

channel and 0.050 to 0.175 for the floodplain.

USGS Model (1992)

In 1992, the USGS developed a computer model of 

the lower Coeur d’Alene River using the FourPt program to 

estimate metal loading to Coeur d’Alene Lake (Woods and 

Beckwith, 1997). This model extended from the Cataldo to 

the Harrison gaging stations and comprised about 40 cross 

sections. The model also simulated the lateral lakes using 

cross sections. Manning’s roughness coefficients of 0.022 

and 0.060 were used for the main channel and for the river 

banks, respectively. The model explicitly determined the 

discharge entering Coeur d’Alene Lake from the river at 

the Harrison gaging station. The Rose Lake gaging station 

provided river discharge data to estimate metal loading in 

the river and floodplain between the Rose Lake and Harrison 

gaging stations. Model boundaries used 15-minute discharge 

data from the Cataldo gaging station and stage data from the 

Harrison gaging station. However, the model was run using a 

5-minute time step for model stability and convergence. The 

FourPt program (DeLong, and others, 1997) is an unsteady, 

1D model for open channels based on the shallow surfacewater equations. In backwater reaches, discharge is not a 

function of stage alone, and stage-discharge relations do not 

work. There may be many stages for one discharge or many 

discharges for one stage. FourPt can simulate flow conditions 

in various regular and irregular channels. The backwater in 

the river, caused by the lake and Post Falls Dam, prevents 

developing a unique stage-discharge relation at the Harrison 

and Rose Lake gaging stations. A model such as FourPt must 

be used to determine discharges at these backwater sites. No 

sediment transport was simulated, and the streambed in the 

model was unmovable (fixed bed). The model was used to 

determine discharge until 2005, when an ADVM was installed 

to monitor velocity at the Harrison gaging station.

University of Idaho Model (2004)

In 2004, the University of Idaho Center for Ecohydraulics 

Research used the MIKE11 model to develop a river model 

of the Coeur d’Alene River (Borden and others, 2004). This 

model extended from the Enaville gaging station on the 

NF Coeur d’Alene River and the Pinehurst gaging station on 

the SF Coeur d’Alene River to the Harrison gaging station 

on the main stem. The model used 161 cross sections. Cross 

sections were extended to include the floodplain by using data 

from USGS Digital Elevation Models. The lateral lakes also 

were included in the model as storage basins that required 

area-elevation tables for each lake. Manning’s roughness 

coefficients used ranged from 0.024 to 0.028 for the main 

channel and from 0.060 to 0.070 for the floodplain. The 

model used the 15-minute discharge data from the Enaville 

and Pinehurst gaging stations and 15-minute stage data from 

the Harrison gaging station as boundary conditions. The 

model also used the total sediment load curves from Clark 

and Woods (2001) at the upstream boundaries (Enaville and 

Pinehurst gaging stations). 
8 Simulation of Flow, Sediment, Transport, and Sediment Mobility of the Lower Coeur d’Alene River, Idaho

The MIKE11 model simulates 1D unsteady flow 

in channels. It also can simulate erosion, deposition, 

and the transport of sediments in channels. Borden and 

others (2004) simulated two floods—a rain-on-snow 

flood (February 5–March 9, 1996) and a snowmelt flood 

(May 21–July 21, 1998) and produced longitudinal and 

planview animations of these floods. The flood from 

February 5 to March 9 extended across the valley, especially 

near Coeur d’Alene Lake.

Golder Associates Model (2005)

In 2005, Golder Associates, Inc. (2005) used the 

1D steady-flow model, HEC-RAS, to model the lower 

Coeur d’Alene River to assess environmental effects of the 

Post Falls Dam. The purpose of this assessment was to support 

the license renewal of Avista Corporation’s hydroelectric 

facility at the Post Falls Dam on Coeur d’Alene Lake. The 

model used cross sections developed every 0.5 mi from river 

bathymetry data. Only in-channel flows were simulated by 

the model because ground elevation data for bank tops and 

floodplain were not available. A Manning’s n of 0.030 was 

assumed for cross sections at all flows. This model was not 

calibrated to hydraulic or sediment-transport conditions 

(Golder Associates, Inc., 2005). However, model simulation 

results were used to estimate flow velocities and to calculate 

sediment transport and incipient motion characteristics. 

Results showed that velocities in the river increased as lake 

levels decreased for a specified discharge, as is typical of 

backwater conditions. Results also indicated that Post Falls 

Dam did not significantly affect the transport of sediments in 

the Coeur d’Alene River.

Reach Characterization

An understanding of flow types, stage, river discharge, 

hydraulic geometry, and streambed sediments of the 

Coeur d’Alene River is necessary before developing hydraulic 

and sediment-transport models.

Flow Types

The elevation of Coeur d’Alene Lake affects the watersurface elevation of the Coeur d’Alene River in the study 

reach. The lake outlet (Spokane River) is restricted by a 

narrow, elevated, bedrock gorge—the lake is in a naturally 

dammed river valley. Post Falls Dam (RM 101.7), about 9 mi 

downstream of the inlet (fig. 1), augments lake storage and 

raises lake levels especially during summer. The dam controls 

lake outflows and levels from mid-June to mid-November 

(summer and autumn) (Avista Corporation, 2005). Post 

Falls Dam provides hydroelectric power, flood control, and 

irrigation supply. The lake and (or) dam cause water to back 

up (increase water-surface elevation) into the Coeur d’Alene 

River. When flows are high on the Coeur d’Alene and St. Joe 

Rivers (main tributaries), the lake level rises because inflow 

exceeds outflow. As high flows recede, outflows may exceed 

inflows and the lake level falls.

Two types of flow occur in the Coeur d’Alene River in 

the study reach—backwater and free-flowing water. Backwater 

is water backed up or retarded in its course, as compared with 

its normal or natural condition of flow (free-flowing water), 

usually caused by a downstream lake or dam or by a channel 

constriction downstream. Backwater also causes the upstream 

flow depth to increase. Backwater conditions are prevalent in 

the Coeur d’Alene River from the mouth to Cataldo Mission. 

Hypothetical water-surface curves illustrate backwater and 

free-flowing water conditions (fig. 3). Hydraulic engineers 

refer to the backwater curve as an M1 curve and the freeflowing water curve (above critical depth) as an M2

 curve. 

Woodward and Posey (1941), Chow (1959), and Henderson 

(1966) describe such curves. Elongating the upstream channel 

in figure 3, would cause the backwater and free-flowing water 

curves to converge to the normal-depth curve. At the point 

where the backwater curve (M1) approaches or converges to 

the normal-depth curve, the effects of backwater cease. The 

normal-depth curve is sometimes called the no-backwater 

curve (Davidian, 1984). Backwater conditions do not affect 

any water-surface curve at or below the normal-depth curve. 

Figure 3 also illustrates that high downstream water-surface 

elevations cause the convergence point with the normal-depth 

curve to be farther upstream. When downstream water-surface 

elevations are high, the influence of backwater on the reach 

moves upstream. 

In natural channels like the Coeur d’Alene River, the 

curves are not as smooth as shown in figure 3. Flow depth 

changes from point to point along a channel in response to 

differences in channel shape, slope, and roughness. Figure 4

shows backwater, normal depth, and free-flowing water curves 

for the Coeur d’Alene River in the study reach for a model

simulation of 25,000 ft3/s at seven water-surface elevations 

at the Harrison gaging station (12413860) (RM 134.636). In 

figure 4, two curves (2,120 and 2,122 ft) are below the normaldepth curve indicating the reach has free-flowing water for the 

specified discharge and downstream water-surface elevation. 

Five curves are above the normal-depth curve (backwater 

condition). The curve for the downstream water-surface 

elevation of 2,126 ft transitions from backwater conditions 

to free-flowing conditions near RM 141. Figure 4 inset 

shows three backwater curves transitioning from backwater 

conditions to free-flowing conditions between RM 160.5 and 

162.5, a 2 mi reach. For example, the 2,132 ft curve (fig. 4

inset) transitions from backwater to free-flowing conditions 

at RM 161.3, about 0.5 mi downstream of Interstate Highway 

90, and the 2,134 ft curve transitions about 700 ft upstream of 

Highway 90. These transitions occur about 30 mi upstream of 

the Coeur d’Alene River inlet to the lake.

River Stage

Water-surface elevations at gaging stations were obtained 

by adding the river stage and datum at each site. For this 

study, the North American Vertical Datum of 1988 (NAVD 

88) datum was used. River stages (or water-surface elevations) 

have been measured on the Coeur d’Alene River at Harrison 

since 1991, at Cataldo since 1920, at Enaville since 1940, 

and at Pinehurst since 1987. River stages at Rose Lake were 

measured from 1995 through 2000. When cross sections 

were surveyed during 2004, datums at gaging stations also 

were surveyed using a Global Positioning System (GPS) 

allowing conversion of all data to one common datum. This 

study used the vertical datum of NAVD 88. Table 1 shows 

datum elevations in National Geodetic Vertical Datum of 1929 

(NGVD 29) and NAVD 88 at six gaging stations on the river

and 2. Differences between NAVD 88 and NGVD 29 are not 

the same everywhere (table 1) because of the Earth’s irregular 

curvature. AVISTA Corporation and others use another 

vertical datum called “lake datum” in the Coeur d’Alene area. 

To obtain elevations in NAVD 88, add 0.80 ft to elevations in 

lake datum.

Since 1903, the Coeur d’Alene Lake gaging station

maximum in spring and early summer and minimum in 

the winter (fig. 5). From the time Post Falls Dam became 

operational in 1907 until 1941, Avista Corporation (2005) 

held the summer and autumn lake level at about 2,127.3 ft 

(2,126.5 ft in lake datum). From 1942 until 2005, the levels 

were 2,128.8 ft (2,128.0 ft in lake datum). The increase 

of 1.5 ft since 1942 probably was due to increasing the 

hydrogeneration at the dam (Hank Nelson, Avista Corporation, 

oral commun., 2005). The maximum water level for the period 

of record was 2,139.8 ft on December 25, 1933, and the 

minimum was 2,120.7 ft on September 12, 1905.

Water-surface elevations for gaging stations on 

Coeur d’Alene Lake and River through the backwater reach 

are similar (fig. 6) but are at different elevations, reflecting 

the variable water-surface elevation of the backwater curve 

(M1) throughout the reach. For example, when elevations 

in Coeur d’Alene Lake (12415500) increase, water-surface 

elevations also increase in the river at Harrison (12413860) 

and Rose Lake (12413810) gaging stations. Water-surface 

elevations at the Harrison gaging station are almost identical 

with elevations at the Coeur d’Alene Lake gaging station.

Stage-relations were developed between the Coeur 

d’Alene Lake gaging station and the Harrison and Rose Lake 

gaging stations (fig. 7) because stage-discharge relations 

cannot be developed at the Harrison and Rose Lake gaging 

stations due to backwater. The curves and equations were 

derived using simple linear regression methods. These 

equations relate the water-surface elevation in the lake to 

water-surface elevations at the respective gaging stations. 

Figure 7 shows the r value (correlation coefficient), i value 

(number of paired data points), and the period of record 

(POR) value for the paired data. The correlation coefficient 

is a measure of strength of the linear relation between two 

variables (Zar, 1998). An r value of 0 indicates that no linear 

association exists between the two variables, whereas, an 

r value of 1 or -1 indicates a strong linear association. The 

correlation coefficient of water-surface elevations for the 

lake and Harrison gaging stations was 0.99 (very strong 

correlation). The correlation of water-surface elevations for 

the lake and Rose Lake gaging stations was a little weaker 

(r = 0.92) but was still strongly correlated. The r value 

decreased as distance increased from Coeur d’Alene Lake, 

probably because of the influence of inflows from intervening 

drainages, influence of inflows and outflows between the 

lateral lakes and floodplain, and (or) effects of backwater in 

the river.

The simple linear regression curves in figures 7A and 7B

fit the data reasonably well. The curve shown in figure 7B is 

not accurate when water-surface elevation in the lake is greater 

than 2,128 ft because the data trend in another direction 

from the regression curve. The relation in figure 7B can be 

improved by using several linear regressions or non-linear 

function(s) that describe the entire dataset more accurately.

River Discharge

The Coeur d’Alene River has no dam or flood control 

structures and is subject to seasonal and peak flows. Discharge 

data have been collected at three gaging stations in the study 

reach (fig. 8). Continuous data have been collected since 

1940 at the Enaville gaging station, 1987 at Pinehurst, and 

1912–13 and 1920 at Cataldo except from 1973 to 1986 when 

the gaging station was not in operation. Figure 8 shows annual 

and seasonal patterns of discharge. Discharge is highest in 

winter and spring due to rainstorms and (or) snowmelt runoff 

and lowest in late summer and autumn when flows rely on 

base flow conditions. Mean annual discharge at the Cataldo 

gaging station is about 2,500 ft3/s. At Enaville, mean annual 

discharge is about 1,900 ft3/s, and at Pinehurst, about 510 ft3/s 

(Brennan and others, 2006). At Cataldo, average spring runoff 

is about 15,000 ft3/s and summer discharges usually are less 

than 600 ft3/s (fig. 8). The highest annual mean flow (1974) 

was about 3,300 ft3/s and the lowest (1977) was about 600 ft3/s 

(Brennan and others, 2006). For the greatest flood of record 

(January 16, 1974), mean daily discharge and instantaneous 

peak flow were 50,000 ft3/s and 79,000 ft3/s, respectively. For 

this event, indirect computations were used to estimate the 

mean daily discharge and instantaneous peak flow because 

the gaging station was not in operation. The February 9, 

1996, flood produced a mean and instantaneous peak flow of 

56,000 ft3/s and 70,000 ft3/s, respectively (Brennan and others, 

2006; updated from Beckwith and Berenbrock, 1996).

Borden and others (2004) noted the volume of discharge 

passing gaging stations on the NF (Enaville) and SF 

(Pinehurst) does not sum to discharge at Cataldo (QEnaville+ 

QPinehurst ≠ QCataldo). Usually, the discharge sum from the 

Enaville and Pinehurst gaging stations was less than at the 

Cataldo gaging station (QEnaville+ QPinehurst < QCataldo). Borden and 

others (2004) attributed these differences to additional river 

discharges from intervening drainages and to streamflow gains 

and losses from the ground-water system. 

Peak flow (flood) estimates for selected recurrence 

intervals at gaging stations on unregulated and undiverted 

streams in Idaho were developed by Berenbrock (2002) using 

peak flow data through 1997. That analysis was statistically 

based and included the Enaville, Pinehurst, and Cataldo 

gaging stations. These flood estimates are used for various 

purposes, such as design of bridges, culverts, and floodcontrol structures, and the management and regulation of flood 

plains. For these purposes, peak flow recurrence intervals 

generally are 50 years or greater. However, there is increasing 

interest in peak flows (floods) with more frequent recurrence 

intervals especially for peak flows that mobilize streambed 

sediments. The peak flow that is probably responsible for 

creating and (or) maintaining the characteristic size and shape 

of the channel (channel-forming flow) has been designated 

as bankfull flow (Leopold and others, 1964; and Knighton, 

1998). Without human influences to streams, bankfull flows 

generally range between the 1.5- and 2.5-year peak flow 

(flood) (Leopold, 1994). For simplicity, bankfull flow for this 

study was defined as the 2-year peak flow although actual 

flows needed to overtop the human affected banks and (or) 

levees is probably higher.

The 100-year and 2-year peak flow estimates from 

Berenbrock (2002) were updated for the Enaville, Pinehurst, 

and Cataldo gaging stations to include an additional 10 years 

of peak flow data since 1997. The resulting estimates for the 

100-year peak flows at Enaville, Pinehurst, and Cataldo gaging 

stations are 56,200, 14,300, and 69,000 ft3/s, respectively, and 

updated estimates of the 2-year peak flow were 15,000, 3,510, 

and 18,900, respectively. These values were not significantly 

different (less than 5 percent difference) from Berenbrock 

(2002) except for the 100-year peak flow at Pinehurst. One 

reason for the large difference at the Pinehurst gaging station 

is because 20 peak flow values (1988–2007) were used for this 

study as compared to 10 values (1988–97) used by Berenbrock 

(2002). Peak-flow data for the 10 years of record may have 

been collected during an unusually dry, wet, or otherwise 

unrepresentative period, and the data may not represent the 

full range of potential floods at the site; whereas, 20 years of 

record may be more representative.

Channel Cross Sections

The 1D sediment-transport model (HEC-6) requires 

accurate representation of the cross-section geometry. A series 

of cross sections measured at variably-spaced distances along 

lines oriented perpendicular to the flow direction defined 

cross-section geometries. Cross sections were surveyed to 

a common datum. Horizontal control was based on North 

American Datum of 1983 (NAD 83), Idaho Transverse 

Mercator Coordinates. Vertical control was based on NAVD 

88.

In 2004, USGS personnel surveyed about 60 cross 

sections on the Coeur d’Alene River between RM 159.8 at 

Mission Flats to the Enaville (near RM 168.7) and Pinehurst 

(near RM 1.6) gaging stations. Appendix A shows the 

locations of cross sections. A GPS and echo sounder were 

used to obtain bathymetric data, and a GPS was used to obtain 

bank data along cross sections. The GPS and echo-sounder 

data were merged into one dataset and edited using HYPACK 

MAX software by Coastal Oceanographics. Cross sections 

were located to best represent the hydraulic characteristics of 

the river. Cross-section spacing ranged from about 800 ft to as 

much as 3,000 ft. To develop stream channel cross sections, 

the steps used by Barton and others (2004) were followed; 

however, a genetic computer program (Berenbrock, 2006)

was used to reduce the number of echo (depth) soundings 

per cross section from hundreds or several thousands to 

80 or fewer. Berenbrock (2006) showed that cross sections 

produced by the genetic algorithm were representative of the 

original section and processing time was significantly shorter 

than using standard procedures. The bathymetry for six cross 

sections on the SF Coeur d’Alene River was surveyed with a 

GPS because the river could be waded at these sections during 

the survey. Also, six cross sections in the braided reach from 

previous studies were used: four sections from the FourPt 

model (Woods and Beckwith, 1997) and two sections from 

the MIKE11 model (Borden and others, 2004). An indirect 

measurement from the flood of February 9, 1996, was used to 

develop the upper most cross section on the SF (cross section 

1.580).

Several cross sections in the braided reach from the 

FourPt and MIKE11 models (Woods and Beckwith, 1997; 

Borden and others, 2004) were compared with surveyed 

sections from this study to ensure that they were compatible. 

These comparisons showed that cross-section geometries have 

changed very little. Figure 9 compares cross sections from 

the FourPt and MIKE11 models, respectively, with surveyed 

sections. Because of the similarity, it was acceptable to use 

cross sections from the previous FourPt and MIKE11 models 

from the braided reach in this study.

Cross sections in the meander reach (RM 159.8 near 

Mission Flats to RM 134.6 at the Harrison gaging station) 

were developed from gridded and LIDAR data. These cross 

sections (more than 160) are shown on a set of maps in 

appendix A. The gridded data from Avista Corporation are 

a composite of bathymetric data and digitized shoreline 

elevations from aerial photographs obtained at lake elevations 

of 2,126 and 2,128 ft in lake datum. The bathymetry was 

surveyed in 2004 using a dual, side-scan sonar. Control was 

set to the lake datum. LIDAR of the river and floodplain 

from Highway 95 to the lake were taken on August 31, 2004. 

Bathymetric data from Avista Corporation were used for 

the streambed part of the cross section. However, when the 

cross section extended above an elevation of 2,124 ft on the 

river banks, LIDAR data were used to avoid inaccuracies in 

digitizing. The floodplain part of the cross sections was always 

determined using LIDAR data.

The following steps were used to develop cross sections 

in the meander reach (see appendix A for locations of cross 

sections). First, gridded data greater than 2,124 ft were 

eliminated. Second, the gridded and LIDAR data for each 

cross section were merged. Third, the data were ordered from 

left bank (viewed as looking downstream) to right bank, 

with the left-most data point designated as 0 ft. Distance for 

all other data points on the cross section extended from the 

left-most point. Again, cross-section data generally were 

reduced to 80 or fewer points per cross section using a genetic 

computer program (Berenbrock, 2006) designed for this 

purpose.

Each cross section was given a station number in river 

miles corresponding to its location on the river. River miles 

referenced in this report were derived from designations 

by the USGS National Mapping Division on 7.5-minute 

(1:24,000–scale) maps and by the Columbia Basin InterAgency Committee (1964). River miles generally are 

measured in 1-mi increments along the channel centerline in 

an upstream direction, beginning with 0 at the mouth of the 

Spokane River at the confluence with the Columbia River 

at Franklin D. Roosevelt Lake (fig. 1). Since the publication 

of the referenced documents, the channel length in several 

places along the Coeur d’Alene River has changed because of 

bank erosion, deposition, or channel migration. As a result, 

the actual distances between the river mile designators shown 

on the maps are not always exactly 1.0 mi. However, because 

many people are familiar with them and use them for various 

purposes, continued use is appropriate.

To use these river mile designators for identifying cross 

sections, the actual distance between river miles was measured 

from the National Agriculture Imagery Program (NAIP) 

digital orthophotos taken in 2004. Distance between the 

nearest downstream river mile designator to the cross section 

was measured along the channel’s centerline of the digital 

orthophoto. The ratio of cross-section distance to distance 

between river miles was calculated and used as the extension 

in the cross-section name. For example, cross section RM 

156.667 is two-thirds of the way between RM 156 and 157.

Channel cross sections differ between the braided and 

meandering reaches. Cross sections in the braided reach have 

widths greater than 500 ft, depths usually less than 15 ft, and 

average depths less than 10 ft. At low flows, exposed islands 

and (or) bars at these cross sections divide the river into 

separate channels. High flows often submerge many of the 

islands and (or) bars. However, a few permanent islands are 

in this reach near RM 162.5 and RM 167. From RM 165.7 to 

166.8 near Kingston, the channel splits into two branches with 

the main channel located in the left branch. Channel slope in 

the braided reach is about 6.5 × 10-4 ft/ft. Cross sections in 

the meander reach are about 300- to 400-ft wide with depths 

greater than 20 ft. Depths greater than 40 ft occur in and 

around channel bends. Channel slope in the meander reach 

is about 6.5 × 10-5 ft/ft, 10 times less than the slope in the 

braided reach.

Streambed Samples

Information on particle-size distribution came from 

streambed material samples collected by previous investigators 

(URS Greiner, Inc., and CH2M-Hill, 2001; Borden and others, 

2004) and this study. In 1997, four sites were sampled to 

characterize the streambed sediments in the meander reach 

of the Coeur d’Alene River (URS Greiner, Inc., and CH2MHill, 2001). Streambed sediment samples were collected near 

the left bank (LB), left of middle of channel (LMID), right 

of middle of channel (RMID), and near the right bank (RB). 

These samples were collected using a drill core and sent to a 

laboratory for particle-size analysis. The d50 of these samples 

shown in table 2 ranged from 0.016 mm at RM 132.1 near 

Harrison to 0.34 mm at RM 159.6 near Mission Flats. They 

are classified as medium silt and medium sand, respectively. 

The d50 decreased downstream. These samples showed no 

significant variation in d50 across the channel.

Reach Characterization 17

In 2001, the University of Idaho (Borden and others, 

2004) sampled five sites in the braided reach. Wolman 

(1954) described the sampling method used to determine 

the size distribution of sediments along the surface of the 

streambed. Samples included only particles larger than 4 mm 

(Borden and others, 2004) from the armored surface layer, 

the topmost layer. A 1⁄2 phi (φ) gravelometer, that measures 

the intermediate axis of a particle, was used to sample the 

armored-surface layer. Armoring is not present in sandbed 

dominated reaches, (for example, the meandering reach). 

Sediments in an armored surface layer commonly are larger 

than the underlying channel fill. These sediments tend to 

armor or protect the streambed from erosion under low- to 

moderate-flow conditions. The d50 of bed material below the 

armored layer ranged from 18.8 to 53.7 mm (table 2), and 

d50 decreased downstream. These samples were classified as 

coarse gravel to very coarse gravel (table 3). Particle-count 

analysis from Borden and others (2004) indicated the largest 

particle on the surface layer was 128 mm—the approximate 

thickness of the armored-surface layer. A particle of this size is 

considered coarse cobble (table 3). The smallest d50 was in the 

SF probably because of the additional sediment contribution or 

loading of fine sediments from mine tailings.

In 2005, four additional samples were collected to 

better define the streambed in the Dudley reach for use in a 

1D sediment-transport model (HEC-6) and a 2D hydraulic 

and bed-shear stress model. These samples were collected 

using a ponar dredge sampler near the center of the channel. 

Particle-size analysis was conducted on these samples using 

the equipment and facilities at the Department of Engineering 

Laboratory, Boise State University. The methods and 

procedures used for the particle-size analyses are outlined in 

the American Society for Testing and Materials’ Manual on 

Test Sieving Methods (1985), the USGS Vancouver Sediment 

Laboratory’s Quality Control and Quality Assurance Plan

2000), and the American Society of Civil Engineers’ Manual 

on Sedimentation (1975). These samples were analyzed using 

the dry-sieve method described in the references above to 

determine the percent-finer-than and the cumulative percentfiner-than fractions, and the particle-size characteristics.

Table 2 shows the d50 and particle-size and classification 

of the four Dudley reach samples. The cumulative percentfiner-than fractions and other particle-size characteristics 

are provided in appendix B. The d50 ranged from 0.31 to 

0.59 mm (table 2) and was classified as medium to coarse 

sand, respectively. The d50 decreased downstream. In sample 

D1 (cross section 157.067), three large particles with 

diameters (measure of intermediate axis) larger than 5 mm 

(fine gravel) were interspersed in a matrix of moderatelysorted sand (appendix B). This sample also included particles 

ranging from 2 to 4 mm (very fine gravels). Therefore, the d50

classification of this sample was medium sand. One particle

Sediment-Transport Characteristics

Sediment-transport models also require data on the 

variation of total sediment discharge (suspended-sediment 

discharge [fine and sand] plus bedload) with changes in stream 

discharge at the upstream model boundary. Measurements of 

suspended-sediment discharge also are required to test model 

performance.

The available supply of fine-grained particles typically 

controls the suspended-sediment discharge of fine-grained 

particles in a stream because the supply often is less than 

the stream can transport (Colby, 1956). These fine-grained 

sediments move downstream at about the same velocity as the 

water.

In contrast, the supply of coarser grained sediments in 

streams generally is greater than the stream can transport; 

therefore the transport of coarser grained sediments as bedload 

typically is controlled by the ability of the stream to transport 

them (Guy, 1970). Bedload is sediment that moves on or 

near the streambed by sliding, rolling, or bouncing (Edwards 

and Glysson, 1999). Most bed sediment moves occasionally, 

but remains at rest much of the time, especially in gravel/

cobble/boulder streams. Because of these differences in 

transport mechanisms, large variations can be expected in 

the concentrations and grain-size characteristics of sediments 

at different locations in a stream and with changes in stream 

discharge. Fine- and coarse-grained sediment concentrations in 

a stream increase with increasing stream discharge (Edwards 

and Glysson, 1999).

Suspended Sediment

Since the study of Clark and Woods (2001) ended in 

April 2000, additional suspended-sediment samples have been 

collected at three sites in the study reach: NF Coeur d’Alene 

River at Enaville (12413000), SF Coeur d’Alene River 

near Pinehurst (12413470), and Coeur d’Alene River near 

Harrison (12413860). The first two sites are at the upstream 

boundary of the study area, and the last site (Harrison) is at 

the downstream boundary. Clark and Woods (2001) collected 

samples only at the Rose Lake gaging station (12413810) 

and provide a complete description on the collection, quality 

control, and processing of suspended sediments.

Clark and Woods (2001) developed relations between 

suspended sediment and river discharge from data collected 

between February 1999 and April 2000. They used a power 

function to develop transport curves for sediment discharge. 

First they converted suspended-sediment data from milligrams 

per liter to tons per day using Qs = Q × Cs × k, where Qs is 

suspended-sediment discharge, in tons per day; Q is stream 

discharge, in cubic feet per second; Cs is suspended-sediment 

concentration, in milligrams per liter; and k is a conversion 

factor of 0.0027. A relation between Qs and Cs then was 

developed for each gaging station. The data pairs for the 

Enaville and Pinehurst gaging stations (Clark and Woods, 

2001) showed a strong correlation (r = 0.974 and r = 0.945, 

respectively); however, the Rose Lake and Harrison gaging 

stations showed a weaker correlation (r = 0.888 and r = 0.829, 

respectively). The r value increased as distance increased from 

Coeur d’Alene Lake probably due to the effects of backwater 

in the river.

The relations between suspended sediment and river 

discharge were then updated using the same procedures 

as Clark and Woods (2001). The old and new regression 

curves and new equations and correlation coefficients for 

the Enaville, Pinehurst, and Harrison gaging stations for 

suspended sand discharges are shown in figure 10. 

The old and new regression curves and new equations for 

suspended fines (silt and clay) discharges, and the sampled 

data pairs are shown with the relations in figure 11. No 

updated curve was available for the Rose Lake gaging station 

because no suspended-sediment samples were collected since 

Clark and Woods’ (2001) study. The data pairs for these sites 

had a strong correlation (r ≥ 0.90). The highest r value of 

0.964 occurred at the Enaville gaging station for suspended 

sand discharge, and the lowest r value of 0.906 occurred at 

the Harrison gaging station for suspended fine discharge. 

For these sites, the scatter amount about the regression line 

is minimal. However, for the Pinehurst gaging station, a fair 

amount of scatter is around the regression line in suspended 

fine (silt and clay) and sand discharges. Clark and Woods 

(2001) attributed the scatter to hysteresis. 

Total Sediment Discharge

Suspended-sediment discharge (fines and sands) plus 

bedload data were used to determine total sediment discharge. 

Bedload samples were collected during Clark and Woods’ 

(2001) study, and since then, no bedload samples have been 

collected. The bedload curves from Clark and Woods’ (2001) 

were used without modification. Total sediment discharge 

(QT) and total suspended-sediment discharge curves for the 

Enaville, Pinehurst, Rose Lake, and Harrison gaging stations 

are shown in figure 12. The bedload contribution to total 

sediment discharge is small; typically less than 15 percent 

(Knighton, 1998). Emmett (1975) indicated that bedload 

contribution ranged from 1 to 10 percent for streams in the 

upper Salmon River basin. Clark and Woods (2001) indicated 

the contribution from bedload from Enaville and Pinehurst 

gaging stations was less than 10 percent. For the Rose Lake 

and Harrison gaging stations, the bedload contribution was 

less than 1 percent. Although bedload was sampled several 

times at the Harrison gaging station, no sediments were 

collected in the samplers even at a discharge of 24,500 ft3

/s 

(April 16, 2002). Thus, an assumption of zero bedload was 

made at the Harrison gaging station. Total sediment discharges 

(QT

) for the Enaville and Pinehurst gaging stations were used 

to estimate the total sediment-transport discharge for any river 

discharge at the upstream boundary of the sediment-transport 

model. Sediment discharge at the Harrison gaging station was 

used to test the sediment-transport model.

22 Simulation of Flow, Sediment, Transport, and Sediment Mobility of the Lower Coeur d’Alene River, Idaho

Comparison of total sediment discharges (QT) from 

the Enaville and Pinehurst gaging stations indicates that on 

an equal discharge basis, the contribution of total sediment 

discharge (QT) is greater from the South Fork than from the 

North Fork. Total sediment discharge of the South Fork near 

Pinehurst is about 10 times greater than from the North Fork at 

Enaville for river discharges ranging from 100 to 10,000 ft3/s. 

For river discharges ranging from 1,000 to 5,000 ft3/s, total 

sediment discharge on the South Fork near Pinehurst is about 

15 times greater than the North Fork at Enaville. Because 

water discharge is much greater from the North Fork than the 

South Fork, the annual contribution of sediment discharge to 

the main stem is greater from the North Fork than the South 

Fork. For example, in water year (WY) 1996, QT for the North 

Fork at Enaville was 381,000 ton/d and for the South Fork 

near Pinehurst was 73,400 ton/d, about one-fifth of Enaville. 

On average in WY 1996, river discharge at the Enaville gaging 

station was four times greater than the river discharge of 

Pinehurst.

Numerical Modeling

The primary objective of numerical modeling was to 

simulate the effects of changing river discharges and lake 

stages in the Dudley reach on velocities, bed shear stress, 

erosion and deposition, and sediment mobility. Successful 

models can be used to estimate water-surface elevations, flow 

depths, velocities, shear stresses, erosion, deposition, and 

sediment transport for flows of varying magnitudes and stages.

HEC-6 Model Implementation

The HEC-6 computer model, version 4.2, (U.S. 

Army Corps of Engineers, 1993) was used to construct 

a sediment-transport model of the Coeur d’Alene River. 

Sediment-transport processes were not simulated in most 

previous modeling studies of this reach, and the streambed 

was assumed to be stable (fixed bed). However, in this 

study, sediment-transport processes were simulated because 

the model was developed to include a movable streambed. 

The modeled reach extended from Enaville on the NF to 

Springston, about 1.5 mi upstream of the Coeur d’Alene River 

inlet to the lake—an actual flow distance of 35.0 mi. The 

actual flow distance on the SF is 1.6 mi; therefore, the total 

model length is 36.6 mi.

HEC-6 is a computer program that analyzes 1D, 

gradually varied, steady flow in open channels with movable 

boundaries due to scour and deposition (U.S. Army Corps of 

Engineers, 1993). In areas where flow velocity is changing 

rapidly, the gradually varied flow assumption requires the 

use of closely-spaced cross sections. The HEC-6 model uses 

the standard step method (Chow, 1959) to determine changes 

in water-surface elevations from one cross section to the 

next by balancing total energy head at the sections. This 1D 

model assumes that energy is uniform in a cross section. This 

assumption is only valid at locations where flow is parallel 

to the main channel or where vertical velocities are not 

significant. The simulated channel does not account for debris 

because the model assumes unobstructed flow. Also HEC-6 

cannot simulate flows through bridges or culverts because the 

program does not include equations to simulate these features.

HEC-6 allows for simultaneous erosion and deposition 

to occur depending on the competency of the stream to 

transport suspended sediment and bedload. However, HEC-6 

does not allow bank erosion or lateral channel migration. This 

model can simulate the transport of sediment from upstream 

sources, transport of bed and suspended loads, and the effects 

of an armored surface layer on flow. The model can simulate 

transport of sediment sizes as large as 2,048 mm and includes 

11 predefined sediment transport equations. The model also 

can simulate the transport of silt and clay. The model first 

calculates the water-surface elevation at each cross section 

using the standard step method. The potential sediment 

transport rate at each cross section, combined with the flow, 

determines the suspended sediment volume in each reach. 

If this volume exceeds the transport capacity of the reach, 

deposition occurs in the reach. If the volume is less than the 

transport capacity of the reach, scouring occurs. After each 

time step, the model updates the channel geometry in each 

section of the reach to account for the effects of scour and 

deposition. Finally, the flow value from the next time step is 

read and a new water-surface elevation is calculated using the 

updated channel geometries. This procedure is repeated until 

the model completes all specified time steps. The number of 

time steps is based on trial-and-error simulations to determine 

when changes in streambed elevations are minimal between 

one time step and the next. Sediment-transport calculations are 

performed by grain-size class, allowing the model to simulate 

hydraulic sorting and to control the rate of erosion and 

redeposition of sediment during the simulation period.

The HEC-6 model requires the user to select a sedimenttransport equation. Eleven transport functions are available 

in the HEC-6 model. These equations were developed under 

different flow, hydraulic, and sediment conditions. Some 

of these equations are used for sandbed streams, gravelbed 

streams, or both; small streams, large streams, or both; and 

some are used to simulate bedload, suspended load, or both 

(total load). Stream-discharge equations based on streampower concepts are more accurate than those based on other 

concepts, such as the shear-stress approach of Kalinske 

(1947) and Meyer-Peter and Müller (1948), the probabilistic 

approach of Einstein (1950), and the regression-equation 

approach of Rottner (1959), as described in Yang and Huang 

(2001) and Gomez and Church (1989). The Coeur d’Alene 
Numerical Modeling 23

River study reach, required a sediment-discharge equation 

capable of computing the total load, consisting of sediment 

particles ranging in size from very-fine sands to cobbles. 

The Ackers and White (1973) equation fulfilled the transport 

equation requirement for the HEC-6 simulations. In a paper 

about accuracies of transport equations, Yang and Huang 

(2001) indicated the Ackers and White (1973) equation was 

accurate for a wide range of stream power and sediments sizes. 

Muskatirovic (2005) also showed that the Ackers and White 

(1973) equation fit measured data more closely than other 

equations for streams in the Salmon River Basin. This leads 

to the conclusion that use of a stream power type equation is a 

reasonable approach. 

Model input consists of data describing cross sections, 

incoming sediment transport loads, distribution of streambed 

sediments, boundary conditions (discharge and stage), and 

time steps. The HEC-6 User’s Manual (U.S. Army Corps of 

Engineers, 1993) provides complete explanations of model 

input and shows examples of model inputs. An example of 

HEC-6 model input for calendar year 1999 is presented in 

appendix C.

Model Cross Sections

The 234 cross sections used in the model included 62 

that were surveyed in the field, 161 that were quantified using 

bathymetry and LIDAR data, and 11 that were interpolated 

from two adjacent surveyed sections. A series of maps in 

appendix A show the locations of cross sections. The fieldsurveyed cross sections are located in the braided reach, and 

cross-section data were collected using GPS and echo-sounder 

equipment, electronic total station, and (or) transit. Of the 

field-surveyed cross sections, four were used from the FourPt 

model (Woods and Beckwith, 1997) (cross sections 160.859, 

161.705, 161.873, and 162.081) and three from the MIKE11 

model (Borden and others, 2004) (cross sections 164.137, 

167.004, and 167.676). The 161 cross sections developed from 

bathymetry and LIDAR data are located in the meander reach. 

Seven bridges cross the river in the study reach—five 

roadway-highway and two bike trail. Three of the bridges 

(Highway 3 bridge near River Mile 150, Highway I-90 bridge, 

and old Highway I-90 bridge) have piers in the river. The ratio 

of bridge-pier area to flow area for these bridges was less 

than 5 percent; thus, the piers probably do not significantly 

constrict the river’s discharge through the bridge. HEC-6 

does not allow for the simulation of bridges because the 

program does not include equations to simulate these features. 

Discharge measurements around these bridges during high 

flows would help determine if the configuration of these 

bridges and piers effect flow. However, cross sections at or 

near the bridges were used in the model. 

Eleven interpolated cross sections (162.506, 162.599, 

162.692, 162.948, 165.685, 165.719, 166.157, 166.255, 

166.353, 166.543, and 166.636) were generated at various 

locations along the braided reach by interpolating data from 

two adjacent cross sections to minimize flow conveyance 

changes between the surveyed cross sections, thus, 

maintaining computational stability. For example, cross 

section 166.543 was interpolated from upstream cross section 

166.729 and downstream cross section 166.451. Interpolation 

was computed by weighting the data from the two cross 

sections by the distance from the interpolated cross section. 

Interpolated cross section 166.543 was one-third of the 

distance from downstream section 166.451 and two-thirds of 

the distance from upstream section 166.729. This interpolation 

was done using a feature in the HEC-RAS model (Brunner, 

2002a, 2002b; Warner and others, 2002). Interpolated cross 

sections improve model convergence and the solution used to 

determine the water surface.

The model used actual flow distances between cross 

sections, not the distance from subtracting river-mile 

designators for cross sections. Average difference in the 

study reach between actual flow and river-mile designator 

distances is about 35 ft. Using actual flow distances gives a 

better estimate of friction losses than using the more arbitrary 

river-mile designator distances. For example, the actual flow 

distance between cross sections 136.025 and 136.226 is 

1,338.9 ft. Based on river-mile designators, the distance is 

1,061.3 ft, a difference of 277.6 ft. 

Model Boundaries

Flow in the study reach is subcritical. Therefore, the 

model requires discharge data at the upstream boundaries 

(cross section 168.713 on the NF and cross section 1.580 

on the SF), and water-surface elevation at the downstream 

boundary (cross section 134.636). Discharge at the upstream 

boundary on the NF (cross section 168.713) was based on 

discharge data from the Enaville gaging stations (12413000). 

Discharge at the upstream boundary on the SF (cross section 

1.580) was based on discharge data from the Pinehurst gaging 

station (12413470). Also discharge was added to cross section 

166.729 near Kingston to account for additional discharge 

from intervening drainages and ground-water gains and losses 

between the NF and SF and the Cataldo gaging stations. 

Water-surface elevation at the downstream boundary (cross 

section 134.636) was based on adding stage data from the 

Harrison gaging station (12413860) and the NAVD 88 datum.

Model Calibration

Calibration is the process of adjusting model parameters 

within reasonable limits to obtain the best fit of model 

simulation results to measured data. The process is to 

repeatedly adjust a parameter, run the model, and inspect the 

differences between model simulation results and measured 

data with the objective of minimizing the differences. 
24 Simulation of Flow, Sediment, Transport, and Sediment Mobility of the Lower Coeur d’Alene River, Idaho

For this model, calibration consisted of comparing the 

difference between simulated and measured water-surface 

elevations at Rose Lake (12413810), Cataldo (12413500), 

Enaville (12413000), and Pinehurst (12413470) gaging 

stations (fig. 2). Four historical stage-discharge conditions in 

1996 and 1997 were identified where discharge and watersurface elevation remained steady through the study reach at 

least for several days. During this period, high river discharges 

occurred and the Rose Lake gaging station was operational. 

Discharge on the main stem of the Coeur d’Alene River 

was based on daily mean discharge from the Cataldo gaging 

station. On the main stem just downstream of the confluence 

of the NF and SF at cross section 167.676, discharges 

from both river forks were added. Also on the main stem, 

discharge was added or subtracted to cross section 166.729 

near Kingston to account for differences in discharge between 

the NF plus SF and the Cataldo gaging station. Discharges 

for the NF and SF were based on the Enaville and Pinehurst 

gaging stations, respectively, for the same period as the 

Cataldo gaging station. Water-surface elevations at gaging 

stations were calculated by adding the daily mean stage to 

the NAVD 88 datum and were calculated for the same period 

as discharges. In the model, Manning’s n values (roughness 

coefficient) were used as a calibration parameter. Model 

calibration was considered acceptable when the difference 

between simulated and measured water-surface elevations for 

each calibration condition was within ±0.15 ft.

Results from the water-surface elevation calibrations 

are shown in table 4. Differences in water-surface elevations 

ranged from -0.11 to 0.09 ft. Only Manning’s n values of 

the streambed were adjusted during this process because no 

field-determined n values were available. Adjustments were 

made equally to cross sections in each reach. Six reaches were 

defined, with the longest consisting of the entire meander 

reach (RM 134.6 to RM 159.8). The NF and SF also were 

defined as one reach. Figure 13 shows the final n values for the 

four reaches on the main stem. The n values for the NF ranged 

from 0.034 to 0.050, and SF ranged from 0.025 to 0.041. The 

n values in all six reaches decreased as discharges increased. 

No adjustments were made to the n values for the banks, 

which ranged from 0.029 in the meander reach to 0.045 in the 

NF and SF.

River discharge and stage data for calendar year 1999 

also were simulated as a check on the reasonableness 

of sediment transport prior to attempting management 

simulations because no sediment-transport parameters were 

available to adjust in the HEC-6 model. Calendar year 1999 

was selected because suspended-sediment samples were 

taken during that year and flow did not overtop banks and 

(or) levees. River discharges on the main stem were based 

on daily mean discharges at the Cataldo gaging station 

(12413500). River discharges for the NF and SF were based 

on the Enaville and Pinehurst gaging stations, respectively, for 

1999. Water-surface elevations at the Harrison gaging station 

were calculated by adding the daily mean stage for 1999 to 

the NAVD 88 datum. The incoming total sediment discharges 

(QT) from the Enaville and Pinehurst gaging stations were 

estimated from QT curves shown in figure 12. A time step of 

0.1 day was used requiring 3,650 iterations to complete the 

simulation for calendar year 1999. 

Simulated HEC-6 sediment discharges for calendar 

year 1999 for sand transport (particle size equal to and 

greater than 0.00625 mm) are shown in figure 14. Measured 

and simulated sand transport were compared at the Rose 

Lake and Harrison gaging stations. Only sand transport was 

considered because sand particles are heavy enough to be 

deposited on the streambed, whereas clay and silt particles 

(considered the “wash load”) have low settling velocities 

and thus are transported in suspension with few of these size 

classes deposited on the streambed. Generally, simulated and 

measured sand discharges agreed with one another (fig. 14). 

Additional sediment samples at Rose Lake and Harrison and 

other areas in the study reach are needed—especially at higher 

river discharges—and would enhance existing datasets and 

allow the extension of sediment rating curves. Additional 

sampling also would help to improve model accuracy, 

especially during higher discharges when most transport 

occurs.

Simulation of Erosion, Deposition, and Sediment 

Transport under Varying Conditions

The calibrated model was verified as capable of 

simulating water-surface elevations and also was reasonable 

in simulating sand sediment discharge. Therefore, it can 

be used to test management alternatives such as dredging 

the streambed. The model can simulate changes in watersurface elevations, sediment transport, and streambed 

elevations (erosion and deposition) resulting from various 

alternatives. The HEC-6 model provides a dredging option to 

remove sediments from the streambed. Sediment transport, 

aggradation, and (or) degradation in the modeled reach 

are important factors, especially for determining substrate 

quantity.

For this study, four management alternatives were 

simulated. The configuration of the streambed in the model 

for all four management alternatives was altered in the 

Dudley reach to simulate dredging of the river channel. In 

management alternatives 3 and 4, the incoming total sediment 

discharge from the SF was decreased by one-half. Stage and 

discharge data for calendar year 2000 were used in alternatives 

1 and 3 because river discharge probably did not overtop 

banks and (or) levees in the Dudley reach, and one large single 

peak (mean daily discharge of 26,100 ft3

/s) was measured, 

which represents about a 4-year flood. The 4-year flood has 

a 25 percent chance of occurring in a given year. Stage and 

discharge data for calendar year 1997 were used in alternatives 

2 and 4 because flows probably stayed within the confines 

of the channel in the Dudley reach, and several large peak 

flows were measured. The peak flows in 1997 were similar in 

magnitude to the single peak in 2000. 

River discharges on the main stem were based on daily 

mean discharge at the Cataldo gaging station. Discharges on 

the NF and SF were based on the daily mean discharge at the 

Enaville and Pinehurst gaging stations, respectively, and watersurface elevations at Harrison gaging station were calculated 

by adding the daily mean stage to the NAVD 88 datum. On 

the main stem just downstream of the confluence of the NF 

and SF at cross section 167.676, discharges from both forks 

were added. Also on the main stem, daily mean discharge was 

added or subtracted near Kingston (cross section 166.729) to 

account for differences in daily mean discharge between the 

NF plus SF and the Cataldo gaging station. All simulations ran 

for one year using a time step of 0.1 day. An additional day 

was simulated in 2000 because it was a leap year.

Dredging in Dudley Reach

For management alternative 1, river discharge and stage 

data from calendar year 2000 were used in the simulation. 

The incoming total sediment discharges from the NF and 

SF were determined from the total sediment discharge 

curves (fig. 12) for the respective river discharges. Before 

the simulation began, the configuration of the streambed 

in the model was altered at seven cross sections (156.135, 

156.213, 156.286, 156.351, 156.399, 156.454, and 156.504) 

in the Dudley reach to simulate dredging of the river channel. 

These changes resulted in about 296,000 yd3 of streambed 

sediments being removed based on excavating about 20 ft of 

material over a 2,400 ft reach that averaged 175 ft in width. 

River discharge and model simulation results for sediment 

discharge for calendar year 2000 at cross section 156.504 (the 

upstream most cross section in the dredged reach) are shown 

in figure 15. Large amounts of sediment were transported on 

relatively few days in calendar year 2000 (fig. 15A). Model 

simulation results for April 15 showed that about 9,000 tons 

of sediment discharge were transported downstream of cross 

section 156.504. The peak flow of 26,100 ft3/s also occurred 

on this day and represents about a 4-year flood. 

Also, model simulation results showed that about 

6,530 yd3 of sediment were deposited in the dredged reach for 

2000 (fig. 16), which represents 2.2 percent of the dredged 

sediments removed before the start of simulation. Thus for the 

long-term, it would take about 45 years to fill up the dredged 

reach to its original volume, assuming river conditions similar 

to 2000 occurred each year over that period. By the end of the 

simulation, the average increase in the streambed elevation 

in the Dudley reach was about 0.5 ft. The greatest increase in 

streambed elevation was about 1 ft at the upstream end of the 

dredged reach (fig. 16).

Because the 1D model does not simulate flow and 

sediment transport process on the floodplain, it is not clear 

how much erosion, deposition, and (or) sediment transport 

would occur in the channel due to flow that overtop banks. 

The flow that overtops banks along the Coeur d’Alene River 

probably is greater than the channel-forming discharge 

(bankfull flow) because of human influences, such as 

levees, along the river. Because no field data are available 

to determine bankfull flow along the Coeur d’Alene River, 

bankfull flow was estimated from flood frequency and was 

estimated to be the 2-year flood (18,900 ft3

/s). Leopold (1994) 

indicated that bankfull flow usually ranges between the 1.5- 

and 2.5-year floods.

For alternative 2, the channel configuration was altered 

the same as in alternative 1 to simulate dredging. This 

alternative used river discharges and stages from calendar year 

1997 because several large peak flows occurred during the 

year and flows and river discharge probably did not overtop 

banks and (or) levees in the Dudley reach. In addition, twice 

as many days of consecutive flow equaled and (or) exceeded 

bankfull flow (18,900 ft3

/s) in 1997 than in 2000. The total 

flow volume in 1997 was 3 times greater than in 2000.The 

total flow volume for river discharges that equaled and (or) 

exceeded bankfull flow in 1997 was 2.3 times greater than 

in 2000. Nine days of flow exceeded bankfull flow in 1997 

(fig. 15B). The highest daily mean flow in 1997 (25,300 ft3

/s) 

(fig. 15B) was not as high as in 2000 (26,100 ft3/s) (fig. 15A).

Figure 16. Simulated streambed elevations before and after streambed dredging and at the end of simulation for calendar 

years 2000 and 1997, Coeur d’Alene River near Dudley, Idaho. (Locations of cross sections are shown in appendix A.)

Model simulation results showed that the highest sediment 

discharge (about 12,000 ton/d on March 20) did not occur 

simultaneously with the highest peak flow of the year, but 

one day before the 4th highest peak flow. On the day of the 

highest peak flow (April 28), the simulated sediment discharge 

was ranked 7th out of 365 days. Model simulation results 

showed that about 12,300 yd3 of sediment were deposited 

in the dredged reach for the year (fig. 16), which was twice 

as much that was deposited in 2000. This value represents 

4.2 percent of the total volume that was removed before the 

start of simulation in the dredged reach. Therefore, it would 

take about 24 years to fill up the dredged reach to its original 

volume assuming river conditions similar to 2000 occurred 

each year over that period. The thickness of deposition at the 

end of the simulation averaged about 1 ft in the dredged reach 

with the thickest of about 2.5 ft (fig. 16).

Reduction in Sediment Discharge Input

Management alternative 3 applied the same river 

discharge, stages, and incoming total sediment discharge, and 

streambed elevation as those in alternative 1, except that the 

incoming total sediment discharge from the SF was decreased 

by one-half. Model simulation results for this alternative were 

similar to those for alternative 1 (2000) in the Dudley reach, 

dredged, and downstream reaches. The decreased incoming 

total sediment discharge had no effect on the streambed in 
30 Simulation of Flow, Sediment, Transport, and Sediment Mobility of the Lower Coeur d’Alene River, Idaho

the Dudley, dredged, or downstream reaches. The distance 

of the river between the SF and Dudley reach probably is 

long enough for the sediment supply, transport capacity, and 

channel geometry to be balanced for the given discharge and 

stage conditions before reaching Dudley. 

Alternative 4 was simulated using the same river 

discharges, stages, and incoming total sediment discharges, 

and streambed elevation as in alternative 2 (1997) except 

that the incoming total sediment discharge from the SF was 

decreased by one-half, as in alternative 3. Model simulation 

results for this alternative were similar to alternative 2 for the 

Dudley reach. Again, the decreased incoming total sediment 

discharge from the SF had no effect on model simulation 

results in the Dudley, dredged, and downstream reaches.

Model Limitations

A computer model can be a useful tool for predicting 

water-surface and streambed elevations and sediment transport 

response to changes in the riverine system. However, the 

accuracy that a model can project water-surface and streambed 

elevations, and sediment transport is directly related to the 

accuracy and adequacy of the input data used to calibrate the 

model. The model limitations must be taken into account when 

using the model for projections.

The HEC-6 model contains many simplifying 

assumptions about the riverine system. Most important are 

the approximations of 1D flow, gradually varied flow, steady 

flow, movable streambed, and sediment transport. These 

simplifications might cause the model to calculate watersurface and streambed elevations and sediment transport with 

discharges greater than or less than experienced in actual study 

reach conditions. Overall, HEC-6 successfully calculated 

water-surface and streambed elevations and sediment transport 

in the Coeur d’Alene River. However, HEC-6 was not 

designed to account for uneven velocities in a cross section 

(especially in curved sections), uneven water-surface elevation 

in a cross section, or uneven erosion and deposition and 

sediment transport in a cross section. Also, HEC-6 does not 

provide the option to simulate infiltration losses and (or) gains 

in the channel.

The HEC-6 model cannot adequately simulate flow 

and sediment transport processes on the floodplain. Extreme 

events such as the 1996 flood that inundated the entire valley 

(channel and floodplains) cannot be simulated with this model 

and the effects are unknown. Also, the life expectancy of 

dredging from extreme events or bank overtopping flows is 

unknown. Only flows that stayed within the confines of the 

channel can be simulated with the HEC-6 model.

How velocity and sediment transport are distributed 

throughout the study reach evokes many questions that a 1D 

model like HEC-6 cannot answer. Applying multi-dimensional 

models that would simulate river discharge and sediment 

transport more precisely could refine velocity, bed shear stress, 

and sediment transport of the Coeur d’Alene River.

HEC-6 can simulate the transport of sediment sizes 

of 0.0625 mm (0.0025 in.) (very fine sand) and greater. 

The model can account for silt and clay particles less than 

0.0325 mm (0.0013 in). However, shear threshold rates for 

clay and silt deposition and erosion were not available for the 

lower Coeur d’Alene River. These rates are site-dependent 

and may vary by orders of magnitude from one site to another; 

therefore, the results obtained from the model may not be 

reliable. Field measurements in the study reach are needed to 

determine actual shear threshold rates.

The particle size distribution of the streambed was limited 

to a few samples. Many more samples are needed throughout 

the study reach to characterize the streambed adequately. For 

the gravelbed reach, samples are needed of the armored layer 

and underneath the armor layer using specialized approaches 

for collecting samples with armored-surface layers as 

described in Berenbrock and Bennett (2005).

Suspended-sediment and bedload data were used to 

determine total sediment discharge at selected sites in the 

model. Since Clark and Woods’ (2001) study, no bedload 

samples have been collected, and their bedload curves were 

used without modification. The bedload curve for Rose Lake 

gaging station was based only on three samples (Clark and 

Woods, 2001, fig. 17), and at the Harrison gaging station, no 

bedload sediments have been collected by the sampler even 

at a discharge of 25,500 ft3

/s. Thus, an assumption of zero 

bedload was made at the Harrison gaging station, which is 

unrealistic especially during higher discharges. Additional 

sediment samples at Rose Lake and Harrison gaging stations 

and at other areas in the study reach are needed and would 

enhance the existing dataset and allow for the extension of 

sediment rating curves. Additional sampling would help 

improve model accuracy especially during higher discharges 

when most transport occurs.

FASTMECH Model Implementation

Two-dimensional (2D) models are able to simulate 

uneven water-surface elevations, varying velocities, and 

flows in more than one direction in a cross section. These 

models can also simulate the flow curvature in bends or 

eddies, whereas, flow curvature is lost in 1D models. Twodimensional models also can provide better-defined velocities 

and hydraulic and bed shear stresses than 1D models. 
Numerical Modeling 31

Therefore, the FASTMECH model, a 2D model, was used to 

simulate flow and hydraulic conditions for the Coeur d’Alene 

River in and around Dudley, Idaho.

FASTMECH is a computer program that analyzes 2D 

steady flow in channels and floodplains with a fixed bed. 

FASTMECH is a steady-state model using a structured 

curvilinear grid, based on the 2D, vertically averaged, shallow 

water equations (McDonald and others, 2001; Nelson and 

others, 2003; Simões and McDonald, 2004; and McDonald 

and others, 2006). The model also calculates the vertical 

distribution of the primary and secondary velocities about 

the vertically average velocity. These data help calculate the 

shear stress near the bed (τb). Vertical velocity distributions 

were estimated rather than computed from the shallow water 

equations; nevertheless, they add a partial dimensionality to 

the model. Thus, the FASTMECH model is designated as a 

two and one-half dimensional (2.5D) model.

The FASTMECH implementation encompassed the 

channel between RM 154 to RM 159 (fig. 17), a distance 

of 5.3 mi. The streambed in this model was assumed to be 

fixed and sediment-transport processes were not simulated. 

Nevertheless, bed and critical shear stress can be used 

for estimating sediment mobility, a surrogate of potential 

deposition and erosion. FASTMECH was recently applied to 

an 11-mi reach of the Kootenai River near Bonners Ferry with 

several sharp bends and split flow around an island (Barton 

and others, 2005). The model successfully simulated measured 

water-surface elevations and cross-stream velocities especially 

in bends. FASTMECH also has successfully simulated other 

rivers and floodplains (Conaway and Moran, 2004; Kenney, 

2005; and Kinzel and others, 2005).

FASTMECH assumes flow is steady and incompressible. 

It also assumes flow is hydrostatic (neglecting vertical 

accelerations), and turbulence is treated adequately by relating 

Reynolds stresses to shear using an isotropic eddy viscosity 

(Nelson and others, 2003). Another FASTMECH assumption 

is that flow is unobstructed and free of debris in the channel 

and floodplain. The model uses only the International System 

(SI) of units. The SI system uses the metric system and 

meter of length, kilogram of mass, and second of time as its 

fundamental units.

FASTMECH was the first model incorporated into 

the Multi-Dimensional Surface Water Modeling System 

(MD_SWMS) (McDonald and others, 2001; and Simões and 

McDonald, 2004). MD_SWMS is a graphical user interface 

for pre- and post-processing application for computational 

models of surface-water hydraulics. MD_SWMS can be used 

to build, edit, and run models and view model inputs and 

results. The interface and additional information are accessible 

at http://wwwbrr.cr.usgs.gov/projects/SW_Math_mod/

OpModels/MD_SWMS/index.htm. 

Model Grid and Bathymetric Interpolation

The model grid used in FASTMECH is a curvilinear 

orthogonal coordinate system with a user-defined centerline. 

The grid centerline approximates the mean flow streamline in 

the modeling reach (Nelson and others, 2003) that was defined 

interactively in MD_SWMS. The computational grid used 

to model the Coeur d’Alene River was 8,452 m (27,730 ft or 

5.3 mi) long with 3,371 nodes in the streamwise direction. The 

width was 350 m (1,148.3 ft) with 141 nodes in the crossstream direction. This formed an approximately 2.5 × 2.5 m 

(8.2 × 8.2 ft) grid (fig. 17). Nodes are located at the corners of 

each grid, and 475,311 nodes form the computational grid.

A module in MD_SWMS was used to map bathymetry 

and LIDAR data to each node or coordinates of the model 

grid through a “nearest-neighbor” method. Bathymetry for 

each node was interpolated by a search bin that covered a 

predefined downstream length and cross-stream width. By 

choosing the length and width of the search bin judiciously, 

the user can tune the interpolation to treat situations where 

slopes in the cross-stream direction are steeper than slopes 

in the streamwise direction as frequently observed in alluvial 

rivers. Node interpolation includes all bathymetry and LIDAR 

data points in a search bin. If the search bin contains no data, 

the length and width of the search bin is doubled until at least 

one or more data points are found. Elevations of points in 

the search bin are weighted by distance from the node and 

averaged to obtain a value for each node of the grid. This 

approach works well where channel banks are nearly parallel 

to the grid as was the case for the modeled reach.

Model Boundaries

The FASTMECH model requires specific input 

parameters for each simulation. At the upstream boundary, 

the model requires river discharge. Discharge at the upstream 

boundary was based on discharge data from only the Cataldo 

gaging station (12413500). Flows from intervening drainages 

between the Cataldo gaging station and upstream model 

boundary are small compared to the river discharge in the 

main stem and were considered negligible in the model.

Water-surface elevations at the downstream boundary were 

based on results from the HEC-6 model in a fixed-bed mode 

(see section on “HEC-6 Implementation” for more information 

on the HEC-6 model). Downstream water-surface elevations 

in the HEC-6 model were based on adding stage data from 

the Rose Lake gaging station (12413810) and the NAVD 88 

datum. Boundary conditions for the calibration simulations are 

presented in table 5.

Model Calibration

Calibration for a 2.5D model is similar to the calibration 

for a 1D model. A graphical and statistical model-calibration 

module contained in MD_SWMS allows for calibration 

with measured water-surface elevations and (or) velocities. 

To calibrate FASTECH, the drag coefficient was adjusted 

iteratively until simulated water-surface elevations matched 

measured water-surface elevations at selected sites. 

Physically, this process ensures the roughness used in the 

model accurately simulates head losses in the channel. 

Because measured values of water-surface elevations and 

velocities were not available, water-surface elevation values 

from FASTMECH were compared to HEC-6 at each cross 

section in the 5.3-mi modeled reach. No measured velocities 

were available for the calibration simulations, and thus, no 

additional adjustments were made to the drag coefficient 

because of velocity. For these calibrations, the model was 

run for 3,000 iterations, sufficient to achieve computational 

stability. Model calibration was considered acceptable when 

the difference between FASTMECH and HEC-6 water-surface 

elevations for each cross section was within the ±0.15 ft limit.

FASTMECH was calibrated to five historical discharge 

and water-surface elevation conditions (table 5). Selection of 

historical conditions for model calibration was based on two 

criteria. The first criterion was availability of water-surface 

elevation data at the Rose Lake gaging station (12413810). 

Second, because FASTMECH is a steady-state model, the 

historical discharge and water-surface elevation should be 

stable in the modeled reach for a minimum of 24 hours so 

river conditions approximate steady flow. Calibrated watersurface elevations at the downstream boundary ranged from 

about 2,130 ft to about 2,139.4 ft, and river discharges used in 

the calibration ranged from 10,500 to 28,900 ft3

/s (table 5).

Each node was assigned an initial drag coefficient 

based on the roughness coefficient (Manning’s n) from the 

HEC-6 model. An equivalent Manning’s n value to the drag 

coefficient can be calculated using a depth scale from the 

following equation:

1/3

where

is the Manning's roughness value,

is the dimensionless drag coefficient,

is the mean depth of flow, in ft, and

is the constant for acceleration of gravity, in ft/s .

The following example shows how using equation 1 

estimated the initial drag coefficient. The fourth calibration 

simulation was used for this example, with a river discharge 

of 22,860 ft3/s and a daily mean water-surface elevation 

at the Rose Lake gaging station (12413810) of 2,139.43 ft 

(table 5). The HEC-6 model was simulated in a fixed-bed 

mode with these conditions. From the graph in figure 13, a 

Manning’s n coefficient for a river discharge of 22,860 ft3/s 

in the 2.5D modeled reach was interpolated to be 0.0224 for 

the streambed. From HEC-6 results, mean depth for the 2.5D 

modeled reach was 20.6 ft. Therefore, using equation 1, Cd

was computed to be 0.0026. An initial Cd was computed for 

each calibration simulation and applied uniformly throughout 

the modeled reach.

FASTMECH also incorporates a lateral eddy viscosity 

to represent lateral momentum exchange due to turbulence or 

other variability not generated at the bed (Nelson and others, 

2003). The following equation can be used to compute the 

initial lateral eddy viscosity:

is the average velocity, in m/s, and

is the mean depth of flow, in m.

Continuing with the previous example, the mean depth (H) of 

flow is 20.6 ft. From HEC-6 results, average velocity for the 

modeled reach was 2.6 ft/s. The computed LEV value for this 

example is 0.16 m2/s. An initial LEV was computed for each 

calibration simulation and applied uniformly throughout the 

modeled reach.

Results of Calibration Simulations

Instead of measured water-surface elevation data, 

calibration simulations used water-surface elevation data 

derived from comparison of FASTMECH (simulated) and 

HEC-6 results. Comparisons between models were made at 

cross sections and at the center river node for the FASTMECH 

model. Differences in water-surface elevation between 

FASTMECH and HEC-6 were less than 0.15 ft, except at 

cross section 158.634 in simulation 5 (0.18 ft). Calibration 

results are shown in table 6 and figure 18. The mean absolute 

difference (MAD) error was small for all simulations. Watersurface elevations from FASTMECH and HEC-6 compared 

favorably (fig. 18). Along the middle part of the 2.5D reach 

from RM 156.5 to RM 158.5, water-surface elevations in 

FASTMECH were slightly less than elevations in HEC-6.

Differences also were greater at lower discharges. Only drag 

coefficients (Cd

) were adjusted during calibration.

Calibrated Cd values for each simulation are shown in 

table 6. The calibrated value in simulation 4 was slightly 

higher than the initial value and greater than all other 

simulations probably because the influence of backwater was 

greater due to the high lake stage. Water-surface elevation 

at the downstream boundary of the 2.5D model was about 

2 ft higher in simulation 4 than in simulation 5, which had a 

greater river discharge (table 5). Table 6 also shows calibrated 

LEV values for each calibration simulation. The calibrated 

value in simulation 4 was lower than the initial value. This was 

true for all calibration simulations.

Results from the calibration simulations also included 

depth, velocity, bed shear stress, and sediment mobility. Each 

respective simulation used boundary conditions listed in 

table 5 with each respective simulation.

Flow Depth

Simulated flow depths for river discharges of 10,500, 

14,000, 17,300, 22,860, and 28,900 ft3/s are shown in 

figure 19. Usually depths increased as river discharge 

increased except for simulation 4 where the high lake levels 

in Coeur d’Alene Lake caused high water-surface elevations 

in the river due to backwater conditions. Water-surface 

elevation at the downstream boundary was about 2 ft higher 

in simulation 4 than in simulation 5 (table 5). However, 

river discharge in simulation 5 was about 6,000 ft3/s greater 

than in simulation 4. Simulated water-surface elevations 

throughout the modeled reach were higher in simulation 4 

than in simulation 5. Therefore, flow depths were greater in 

simulation 4 than in simulation 5. The reach from RM 157.0 to 

RM 157.7 was the shallowest in all simulations (fig. 19), and 

the average simulated depth along the thalweg ranged from 

16 ft in simulation 1 to 25.6 ft in simulation 4. The deepest 

point of the modeled reach occurred near RM 158.3 near a 

riverbed, and depths ranged from 43 ft in simulation 1 to 53 ft 

in simulation 4. In the dredged reach between cross sections 

156.066 and 156.563, average depth along the thalweg ranged 

from 21 ft in simulation 1 to about 31 ft in simulation 4 

(fig. 19).

Flow Velocity

Simulated flow velocities for river discharges of 

10,500, 14,000, 17,300, 22,860, and 28,900 ft3/s are 

shown in figure 20. Simulated velocities increased as river 

discharges increased. Average simulated velocities along the 

thalweg ranged from about 3 ft/s in simulation 1 to 5.3 ft/s 

in simulation 5; maximum simulated velocities ranged 

from 3.9 ft/s in simulation 1 to about 7 ft/s in simulation 5.

Figure 19.—Continued.

Velocities in simulation 4 were similar to velocities in 

simulation 3 because of the substantial backwater conditions 

in simulation 4 resulting from the high lake levels. In all 

simulations, the highest velocities occurred in the reach 

between RM 157.0 to RM 157.7 where flow depth is 

shallowest. In this reach, average velocity along the thalweg 

ranged from 3.5 ft/s in simulation 1 to about 6 ft/s in 

simulation 5. At the deepest point of the modeled reach (near 

RM 158.3), average simulated velocity ranged from 4 ft/s in 

simulation 1 to about 6 ft/s in simulation 5. In the dredged 

reach, from cross section 156.066 to section 156.563, average 

velocity along the thalweg was 2.75 ft/s in simulation 1 and 

5 ft/s in simulation 5.

Velocity also can be described by magnitude and 

direction (vectors), whereas, velocity as described above was 

expressed only by magnitude (speed). Vectors usually are 

drawn as arrows pointing in the direction of flow with arrow 

color and (or) size depicting the speed of flow. Vectors of 

velocity are helpful in depicting the flow direction especially 

in reverse flows. Figure 21 shows velocity vectors of the 

dredged reach near Dudley. In the modeled reach, the vectors 

are nearly parallel except near banks and in and around river 

bends. The vectors also show that the highest velocities are 

near the center of the river probably aligned with the thalweg 

except in and around river bends. The maximum velocity 

at cross section 156.213 was 5.8 ft/s and average velocity

was 3.5 ft/s, a decrease of 40 percent (fig. 21). On average, 

maximum velocities at cross sections shown in figure 21

(cross sections 156.135, 156.213, 156.286, 156.351, and 

156.399) were about 60 percent greater than average velocity.

FASTMECH simulated several reverse flows (backeddies). Several back-eddies occurred in a bend in the 

river near cross section 158.259 with a river discharge of 

28,900 ft3/s (fig. 22). A large back-eddy near the left bank 

was about 120 ft wide and about 500 ft long and encompassed 

about one-third of the river width. Flow depth in the center 

of the eddy at cross section 158.259 was about 45 ft. 

Average flow depth throughout the eddy was about 22 ft. 

FASTMECH also simulated two other back-eddies on the 

right bank (fig. 22) . These back-eddies were much smaller in 

size and flow depths were much shallower. Other simulated 

back-eddies in the modeled reach were much smaller than 

the large back-eddy at RM 158.3. No back-eddies were 

simulated by the model in the dredged reach (fig. 21). Backeddies usually trap sediment and debris because of swirling 

or circular flows and slow velocities. If the velocities are slow 

enough, the sediments settle out.

In contrast to the multidimensional (FASTMECH) model, 

the 1D model (HEC-6) did not show or simulate eddies—even 

though a large eddy near cross section 158.259 occupies about 

one-third of the river (fig. 22). This deficiency illustrates why 

a 1D model is not appropriate for this reach. In 1D space, 

variables can have only one value. For example, a 1D hydraulic 

model can have only one value for each variable (velocity, 

water-surface elevation, shear stress, etc.) at a cross section.

42 Simulation of Flow, Sediment, Transport, and Sediment Mobility of the Lower Coeur d’Alene River, Idaho

Rivers with eddies and other complex flow features cannot 

be expressed adequately in 1D space; therefore, multidimensional models are needed to simulate the river more 

precisely as shown in figure 22.

Shear-Stress

Shearing forces associated with river discharge, known 

as shear stress, determine the capability of a river to move 

material. Noncohesive sediment movement occurs when the 

boundary threshold is exceeded (Julien, 2002). The threshold 

is referred to as the critical shear stress. FASTMECH 

calculates boundary or bed shear stress as:

ranged from 1.1 N/m2 in simulation 1 to 3.3 N/m2 in 

simulation 5. The maximum stress ranged from 3.3 N/m2

in simulation 1 to 10 N/m2 in simulation 5 with the highest 

stresses usually occurring in the river bend near RM 158. 

In the reach with the highest velocities and shallowest flow 

depths (RM 157.0 to RM 157.7), average stress along the 

thalweg ranged from 2.4 N/m2 in simulation 1 to 7.6 N/m2

in simulation 5. At the deepest point of the modeled reach 

(near RM 158.3), bed shear stress ranged from 3.2 N/m2 in 

simulation 1 to about 8 N/m2

 in simulation 5. In the dredged 

reach, average stress along the thalweg ranged from 1.6 N/m2

in simulation 1 to 5.3 N/m2 in simulation 5, an increase greater 

than 200 percent.

Sediment Mobility

The model-simulated bed shear stress also was used to 

assess sediment mobility over the five calibration simulations. 

River discharges for these simulations ranged from 10,500 to 

28,900 ft3/s. Sediment mobility for a given particle size occurs 

when the boundary or bed shear stress (τb

) exceeds the critical 

shear stress (τc), in other words τb > τc. This determines only 

whether a given particle size is potentially mobile. Sediment 

mobility provides an indication whether sediment movement 

(transport) occurs. However, bed erosion and deposition also 

depends on sediment supply. Sediment mobility is computed 

from flow depth and bed shear stress.

The following equation was used to determine critical 

shear stress for particle motion:

The Shields diagram provided the Shields parameter θ* for 

each particle size. Table 7 shows critical shear stresses and 

Shields parameter for the particle-size classifications of 

table 3. For example, critical shear stress for medium sand 

ranged from 0.194 to 0.27 N/m2.

In sandbed channels where bedforms are present, such 

as the meander reach of the Coeur d’Alene River, total 

bed shear stress can be comprised of many components 

(McLean, 1992). Thus, for determining only the shear that is 

acting on the particles or grain, partitioning bed shear stress 

(τb) is necessary. Grain shear stress is the resistance due to 

sediment grains on the streambed and is responsible for the 

movement of sediment. The following equation was used to 

determine grain shear stress from total shear stress (Smith and 

McLean, 1977; and Nelson and others, 1993; Bennett, 1995, 

equation 9):

Numerical Modeling 43

This analysis determines whether or not a given grain 

size is mobile, but does not calculate potential for erosion 

or deposition, which is determined by the divergence or 

convergence in the sediment transport rate, and is not 

addressed in this analysis.

Grain shear stress is determined in equation 5 by using 

dune height and length for a related river discharge. Because 

dune heights and lengths were not measured during the study, 

bathymetric data were used to determine if dunes existed in 

the 2D modeled reach. The only well-formed and continuous 

bedforms in the modeled reach were located near the 

downstream end of the modeled reach between RM 154 to RM 

154.5. These dunes extended longitudinally and transversely 

(across) in the channel. Dune heights and lengths in this reach 

averaged 1.1 and 63 ft, respectively. Dunes of partial extent 

(ill-formed) also occurred in other areas of the model reach. 

Bedform geometry is dependent on the flow and sediment 

characteristics and sediment transport rate, and measurements 

of bedform geometry at different river discharges 

would help improve the accuracy of grain shear 

stress and sediment mobility potential.

Therefore, the average height and length 

of dunes from the bathymetry data near the 

downstream end of the modeled reach were 

used to determined grain shear stress and 

sediment mobility in the Dudley reach. Bed 

shear stress in the Dudley reach averaged 

5.7 N/m2 in simulation 5 (river discharge of 

28,900 ft3/s). From equation 5, grain shear stress 

is calculated to be 3.5 N/m2 which corresponds 

to the largest particle size of 5.1 mm that can be 

mobilized. Because of the uncertainty in dune 

characteristics, grain shear stress was calculated 

for a range of dune heights and lengths—0.5 

times (decreasing), 1.0 times, and 1.5 times 

(increasing). If the dune height was not 1.1 ft, 

but was 1.65 ft (1.5 times) (1.1 ft × 1.5 = 1.65 ft), 

grain shear stress would be 2.8 N/m2 and the 

largest mobilized particle would correspond 

to 4.1 mm; similarly, if only dune length was 

increased 1.5 times to 94.5 ft (63 ft × 1.5 = 

94.5 ft), grain shear stress would be 4.0 N/m2

and largest mobilized particle would correspond 

to 5.7 mm. Because of the uncertainty in dune

m2 in the Dudley reach. Changes in grain shear stress were 

less than 3 times from one to another (table 8). If no bedforms 

existed in the Dudley reach, grain shear stress would be 

equivalent to the bed shear stress (5.7 N/m2) and the largest 

mobilized particle would correspond to 8 mm. Appendix D

provides grain shear stress, largest mobilized particle, 

and particle classification for simulations 1 through 5. In 

simulations 1 through 5, areas of greater sediment mobility 

occurred near the thalweg where bed shear stresses (fig. 23) 

were greater; areas of lower sediment mobility occurred near 

the banks and back-eddies where bed shear stress were lower.

46 Simulation of Flow, Sediment, Transport, and Sediment Mobility of the Lower Coeur d’Alene River, Idaho

Model Limitations

Several factors constrain the ability of the FASTMECH 

model to simulate water-surface elevations, velocities, bed 

shear stresses, and sediment mobility: (1) accuracy and detail 

of channel and bank geometry, (2) characterization of watersurface elevations and velocities, (3) characterization of 

bedform geometry, (4) potential errors incurred by applying a 

steady-state model to unsteady flow conditions, and (5) the 2D 

flow approximations. 

FASTMECH was calibrated to the results from a 1D 

model, which limits the accuracy potential of the 2.5D 

model to that of a 1D model. The existing model calibration 

and any future model calibrations would benefit from the 

acquisition of actual water-surface elevations and velocities 

throughout the modeled reach for several river discharges to 

improve the accuracy of the model simulation results. Velocity 

conditions at the upstream model boundary profoundly affect 

flow for roughly the upper 0.5 mi of the model. Additional 

discharge measurements at several river discharges could help 

to determine the velocity distribution across the upstream

boundary. Measurements of the bedform for a range of river 

discharges are needed to enhance estimates of grain shear 

stress and sediment mobility potential. Collection of particlesize distribution data along the streambed and banks also 

could enhance future model calibrations. This information 

would help to improve the accuracy of the modeled results 

especially for bed shear stress and sediment mobility potential, 

and thereby using the full potential of the 2.5D model.

A calibrated, transient, hydrodynamic model could 

provide a more thorough understanding of velocities, bed 

shear stresses, and channel evolution. Steady-state models, 

such as the one presented here, are unable to evaluate the 

effects of changing flow and lake-level conditions on bed 

sediment mobility. To better understand channel evolution, 

a transient-state, 2D sediment transport model would be 

beneficial. Also, this model is limited to river discharges 

contained within the banks and those flood flows that overtop 

the banks and spread onto the floodplain would have to be 

addressed by a multi-dimensional floodplain model with 

sediment transport capability.
Summary 47

Summary

The Coeur d’Alene River originates in the Coeur d’Alene 

and St. Joe Mountains near the Idaho-Montana border and 

flows westward into Coeur d’Alene Lake. At the headwater 

of the river, elevations in the Coeur d’Alene Mountains reach 

6,650 ft. The basin drains an area of about 1,475 mi2 and 

consists of two branches, the North Fork (NF) and the South 

Fork (SF). These rivers reach a confluence downstream of 

Enaville, and then the main stem follows a sinuous path to the 

lake. The study reach is about 35 mi long, starting near the 

towns of Enaville and Pinehurst and continuing downstream 

to Springston near the river inlet to the lake. More than 100 

years of mining in the upper Coeur d’Alene River Basin have 

resulted in large quantities of metal-contaminated sediments 

transported to and deposited in the lower Coeur d’Alene River 

and its floodplain.

In the study reach, the Coeur d’Alene River is 

characterized by a braided reach and a meander reach. The 

braided reach extends upstream of river mile (RM) 159.8 near 

Mission Flats, and the meander reach extends downstream 

from RM 159.8 to the river inlet. Many exposed islands and 

(or) bars are in the braided reach and divide the river into 

multiple channels especially at low flows; the streambed 

primarily is composed of gravels and cobbles. The meander 

reach is a single channel with gentle bends except at RM 

135.25 and RM 149. The streambed in the meander reach 

primarily is composed of sand and silt and is contaminated 

with heavy metals transported from mine tailings in the SF 

basin. Previous studies have shown the highest concentration 

of contaminated sediments is in the streambed in the lower 

Coeur d’Alene River. Some of the highest concentrations of 

lead in the streambed are in the Dudley reach.

A computer sediment-transport model, HEC-6, was used 

to simulate water-surface and streambed elevations, erosion 

and deposition of the streambed, and sediment transport. This 

steady-state, 1D model simulates the resultant erosion and 

deposition averaged across the streambed at any cross section 

in the river reach. The model was calibrated to water-surface 

elevations and discharges at four historical stage-discharge 

conditions. Model calibration was considered acceptable when 

the difference between measured and simulated water-surface 

elevations was ±0.15 ft. Actual differences were ±0.11 ft, 

except for one value. Also, the model was used to simulate 

river discharges and stages for calendar year 1999 as a check 

on the reasonableness of sediment transport. Measured and 

simulated sand transport were compared at the Harrison and 

Rose Lake gaging stations, and the comparisons generally 

agreed with one another.

The calibrated model was used to evaluate the feasibility 

and potential effects of remedial actions (management 

alternatives) on the streambed. Four management alternatives 

were simulated to understand effects from dredging 

the streambed and reducing sediment discharge input. 

Management alternatives 1 and 3 used river discharge and 

stage data from calendar year 2000, and alternative 2 and 4 

used data from calendar year 1997. Calendar year 2000 was 

simulated because flows stayed within the confines of the 

channel, and only one large peak flow (representing about a 

4-year flood) occurred during that year. Calendar year 1997 

was simulated because flows stayed within the confines of the 

channel, and several large peak flows occurred. Also, twice as 

many consecutive days that exceeded bankfull flow occurred 

during calendar year 1997 than during 2000. Before the start 

of simulation in these alternatives, seven cross sections in 

the Dudley reach were deepened 20 ft to simulate dredging. 

About 296,000 yd3

 of streambed sediments were removed by 

dredging.

Results from simulation 1 showed sediments being 

deposited in the dredged reach. About 6,530 yd3 of sediments 

were deposited during 2000, about 2 percent of the total 

volume that was dredged. Thus, about 45 years of stagedischarge conditions similar to those that occurred in calendar 

year 2000 would be needed to fill up the dredged reach. 

For simulation 2 (1997), about 12,300 yd3 of sediment was 

deposited in the dredged reach, about twice as much as in 

2000. About 24 years of stage-discharge conditions similar to 

those that occurred in calendar year 1997 would be needed to 

fill up the dredge reach. 

For alternative 3, model conditions in simulation 1 (2000) 

were used except that the incoming total sediment discharge 

from the SF was decreased by one-half. Results from this 

simulation showed neither differences in deposition nor in the 

elevation of the streambed from alternative 1 in the dredged 

and Dudley reaches because of the reduction of incoming 

total sediment discharge. The distance between the SF and 

Dudley reach is long enough for the sediment supply, transport 

capacity, and channel geometry to be balanced with river 

discharge before reaching the Dudley reach. Alternative 4 

used the same model conditions as those used in alternative 2 

(1997), except that the incoming total sediment discharge from 

the SF was decreased by one-half. Results from this simulation 

also showed no differences in deposition or streambed 

elevation between alternatives 2 and 4 in the dredged and 

Dudley reaches. It may take many years or even decades for 

the river to reach equilibrium conditions after incoming total 

sediment discharge is decreased. Effects from extreme events 

such as the 1996 flood (about a 100-year flood) on the channel 

and floodplain are unknown. 
48 Simulation of Flow, Sediment, Transport, and Sediment Mobility of the Lower Coeur d’Alene River, Idaho

The FASTMECH computer model was used to increase 

understanding of two-dimensional flow hydraulics, in 

particular velocities and shear stresses, as they vary across 

the channel and in river bends. The model covers a 5.3-mile 

reach near Dudley, between river miles 153.9 and 159.2. 

The U.S. Geological Survey Multi-Dimensional Surface 

Water Modeling System (MD_SWMS) was used to build the 

computational grid for FASTMECH. The MD_SWMS also 

was used to edit model input, run the model, and view model 

simulation results. The computational grid was 27,730-ft long 

with 3,371 nodes in the streamwise direction and 1,148.3-ft 

wide with 141 nodes in the cross-stream direction, forming 

an approximately 2.5×2.5 m grid. The computational grid 

included 475,311 nodes. 

Calibration of the FASTMECH model included five 

historical discharge conditions ranging from 10,500 to 

28,900 ft3/s. Only drag coefficients were adjusted during 

calibration. Water-surface elevations at the downstream 

boundary were based on results from the HEC-6 model in 

fixed-bed mode. Results from FASTMECH were compared 

to results from HEC-6, used instead of measured data. 

Differences in water-surface elevation between FASTMECH 

and HEC-6 were less than 0.15 ft, except for one value at 

0.18 ft. The mean absolute difference error and maximum 

difference in water-surface elevation also were less than ±0.15 

ft except for one value.

Results from the calibration simulations of FASTMECH 

also included simulated depth and velocity. The model showed 

that flow depths increased as river discharges increased, 

except for the fourth simulation where high lake elevations 

cause water-surface elevations in the river to be high due 

to backwater conditions. The water-surface elevation at 

the downstream boundary in simulation 4 was about 2 ft 

higher than in simulation 5. However, the river discharge for 

simulation 5 was about 6,000 ft3/s greater than for simulation 

4. The reach from RM 157.0 to RM 157.7 was the shallowest 

in all simulations. In the dredged reach, average simulated 

depth ranged from 21 to 31 ft. Simulated velocities also 

increased as river discharges increased. Average simulated 

velocities along the thalweg ranged from about 3 to 5.3 ft/s, 

and maximum simulated velocities ranged from 3.9 to about 

7 ft/s. In the dredged reach, average simulated velocities along 

the thalweg ranged from 3.5 to 6 ft/s.

The FASTMECH model also showed several areas where 

reverse flows (back-eddies) occurred. These back-eddies 

usually occurred near river bends. A large back-eddy near the 

left bank near RM 158.3 was about 120 ft in width and about 

500 ft in length and encompassed about one-third of the river 

width. Other back-eddies occurred throughout the modeled 

reach but were much smaller. No back-eddies occurred in the 

dredged reach.

FASTMECH also simulated bed shear stress. Simulations 

showed that as river discharge increased, bed shear stress 

increased. Average stress along the thalweg increased more 

than 200 percent from simulation 1 (river discharge of 

10,500 ft3/s) to simulation 5 (river discharge of 28,900 ft3/s). 

Bed shear stress was used to assess sediment mobility 

potential. The potential of sediment mobility occurs when the 

bed shear stress exceeds the critical shear stress of the particle. 

This only determines whether a given particle is potentially 

mobile. Simulated sediment mobility indicated the transport 

of very coarse sand to fine gravel in these simulations. In 

simulation 5, simulated sediment mobility potential indicated 

the transport of very fine gravel to fine gravel. Also these 

simulations showed areas of greater sediment mobility 

potential near the thalweg where bed shear stresses were 

greater. Areas of lower sediment mobility potential were near 

the banks and back-eddies where bed shear stress was lower.

The models developed and calibrated for this study 

closely duplicate measured water-surface elevations and 

sediment discharges. Because the FASTMECH model was 

calibrated only to water-surface elevations from the HEC-6 

model, a better understanding of flow and hydraulics in this 

reach would improve the model if water-surface elevations 

were measured at different flows. Greater understanding and 

improvement to the model would also occur if cross-stream 

and longitudinal velocities were measured throughout the 

study reach at different flows. The FASTMECH model is 

limited to river discharges contained within the river banks. 

Flood flows that overtop the banks and spread onto the 

floodplain would have to be addressed by a multi-dimensional 

floodplain model with sediment transport capability.

Glossary 53

Glossary

armor layer A coarser surficial layer of sediments on the 

streambed. This layer ranges from one particle thickness to 

several. This layer can be quite resistant to scour—usually 

only high flows mobilize this layer and it may re-form as 

flows decrease.

backwater Water backed up or retarded in its course 

as compared with its normal or free-flowing condition. 

Backwater is an increase in upstream flow depth due to a dam, 

constriction in a channel, change in channel slope, or change 

in roughness. Backwater is denoted by hydraulic engineers as 

an M1 curve.

bedform Alluvial-channel bottom feature that depends on 

bed-material size, flow depth, and flow velocity. Bedforms 

include ripples, dunes, antidunes, and plane bed.

boundary or bed shear stress Stress that acts in the direction 

of flow on the streambed. Bed shear stress is often related to 

the ability of flow to move sediment on the streambed.

channel The channel includes the thalweg and streambed.

confluence The flowing together of two or more streams; 

the place where a tributary joins the main stream.

conveyance A measure of the carrying capacity of a channel 

section and is directly proportional to channel discharge. 

Conveyance is that part of Manning’s equation that excludes 

the square root of the energy gradient or friction slope.

critical flow The depth at which flow is at its minimum 

energy. Inertial forces equal gravitational forces.

cross section A series of coordinate pairs of elevation and 

stationing that describes the channel shape perpendicular to 

the mean flow direction.

flood Any relatively high streamflow that overtops the 

natural or artificial banks of a river.

floodplain Land adjoining (or near) the channel of a 

watercourse that is usually dry, but has been, or may be, 

covered by floodwaters. A floodplain functions as a temporary 

channel or reservoir for overbank flows.

free-flowing water Water that is not backed up or retarded 

in its course. Free-flowing water is denoted by hydraulic 

engineers as an M2 or M3 curve.

high-water marks Evidence of the stage reached by a flow. 

High-water marks generally consist of debris, scour marks, or 

staining of rocks along the channel banks.

hydrograph A graph of stage or discharge versus time.

Manning’s roughness coefficient (n-values) or Manning’s 

n A measure of the frictional resistance exerted by a channel 

on the flow. The n value also can reflect other energy losses 

such as those resulting from the transport of material and 

debris, unsteady flow, extreme turbulence, that are difficult or 

impossible to isolate and quantify.

normal depth The depth of flow for a given discharge, fixed 

channel shape, slope, and roughness.

particle-size The size of material on the bed of a stream, 

referenced to a specific diameter (either maximum, 

intermediate, or minimum) of the measured particle.

peak flow See runoff peak flow.

reach A length of stream that is selected to represent a 

uniform set of physical, chemical, and biological conditions.

river bank The sloping ground that borders a stream and 

confines the water in the channel. A river bank is bordered by 

the floodplain and channel.

runoff peak flow The largest value of the runoff flow, that 

occurs during a flood, as measured at a particular point in the 

drainage basin.

slope The change in elevation per unit change in the 

channel’s length.

stage The height of a water surface above gage datum; same 

as gage height.

stage-discharge relation The relation between the watersurface elevation and discharge.

steady flow Discharge and depth of flow does not change 

with time or during a selected period of time.

streamflow, discharge, or flow A general term for water 

flowing through a channel.

subcritical flow If the flow is subcritical, flow depth is 

greater than the flow depth in critical flow. Inertial forces are 

less than the gravitational forces.
54 Simulation of Flow, Sediment, Transport, and Sediment Mobility of the Lower Coeur D’Alene River, Idaho

thalweg A line connecting the lowest points along the length 

of a riverbed. It can be quite sinuous and wander within the 

channel.

transient flow Discharge and depth of flow changes with 

time.

water-surface curves or profile Longitudinal plots of the 

water-surface elevation as a function of distance downstream 

through a channel reach.

water-surface elevation Height of a water surface above 

a datum; same as adding stage and NAVD 88 datum for 

example.

velocity-stage-discharge relation Relation between velocity, 

water-surface elevation, and discharge.
