Stage-Discharge Relations for Selected Culverts and 

Bridges in the Big Lost River Flood Plain at the Idaho 

National Engineering and Environmental Laboratory, Idaho

By Charles Berenbrock and Jack D. Doyle

Abstract

Information is needed by the U.S. Department 

of Energy at the Idaho National Engineering and 

Environmental Laboratory to determine the extent 

and severity of potential flooding at facilities along 

the Big Lost River. Two computer programs—the 

Culvert Analysis Program (CAP) and the HECRAS model—were used to define stage-discharge 

relations for 31 culverts and 2 bridge sites in a 10-

mile reach of the river. These relations can be used 

to improve surface-water-flow models to evaluate 

potential flooding.

Relations between headwater, tailwater, and 

discharge through each structure were unique. 

Discharge through the culverts as computed by the 

CAP ranged from about 0 cubic feet per second to 

as much discharge as could be conveyed, and tailwater elevations ranged from about 0 to 30 feet 

above the outlet elevation. Discharge through the 

bridges, as computed by the HEC-RAS model, 

ranged from nearly 0 to 7,000 cubic feet per second, and tailwater elevations ranged from nearly 0 

to 30 feet above the streambed on the downstream 

cross section of each bridge.

Stage-discharge relations provided in lookup 

tables in this report can be incorporated into 

numerical surface-water-flow models to simulate 

the effects of hydraulic structures on flood flows. 

One limitation of the CAP and HEC-RAS models 

is that changes in flow conditions, such as obstruction by sediment and debris, are not simulated. If 

flow through a hydraulic structure is obstructed by 

sediment or debris, then model-simulated discharges through the structure might be greater than 

would be experienced under actual conditions.

INTRODUCTION

Over the past 5 years, concerns about flooding on 

the Big Lost River at the Idaho National Engineering 

and Environmental Laboratory (INEEL), especially to 

facilities near the river, have prompted a number of 

flood-plain studies. In the reach between the INEEL 

diversion dam and Pioneer diversion structures (fig. 1), 

Ostenaa and others (1999) used a combination of the 

elevation of paleostage indicator sites and a twodimensional surface-water model to estimate paleoflood discharge. Two-dimensional models are ideally 

suited for simulating flows over complex topography 

having spatially variable resistance. These models 

allow flexibility in representing flows in and around 

geometric features such as irregular-shaped water 

boundaries, channels, islands, dikes, and embankments. Most two-dimensional surface-water models 

use defined stage-discharge relations to simulate flow 

through culverts and (or) bridges.

In 2001, the U.S. Geological Survey (USGS), in 

cooperation with the U.S. Department of Energy 

(DOE), began a study to evaluate the hydraulics of culverts and bridges in the Big Lost River and flood plain 

(fig. 1) from the INEEL diversion dam to about 1 mi 

downstream from the U.S. Government railroad near 

the Idaho Nuclear Technology and Engineering Center 

(INTEC). The resulting stage-discharge relations for 

culverts and bridges can be incorporated into numerical 

surface-water-flow models so that the effects of these 

hydraulic structures on flood flows can be simulated 

more accurately.

Purpose and Scope

This report documents the methods for and results 

of determining stage-discharge relations for 31 culvert 

sites in the study area using the USGS Culvert Analysis 

Program (CAP) (Fulford, 1998) and for two bridge 

sites using the U.S. Army Corps of Engineers HECIntroduction

RAS model (Brunner, 2001a, 2001b; Warner and others, 2001). Model-computed stage-discharge relations 

are described in lookup tables by relating three parameters—headwater elevation, tailwater elevation, and 

discharge—through each structure. These relations can 

be incorporated into surface-water models of the Big 

Lost River and flood plain.

Description of the Study Area

The study area is a 10-mi reach located between 

the INEEL diversion dam and about 1 mi downstream 

from the U.S. Government railroad bridge near the 

INTEC facility (fig. 2). The Big Lost River is an 

ephemeral stream in the study area. Near the western 

boundary of the INEEL, the river exits Box Canyon, a 

narrow gorge with nearly vertical walls cut into basaltic 

rocks. On the INEEL, the river typically is incised less 

than 20 ft into surficial sediments and basalts. Channel 

slope from the INEEL diversion dam to State Highway 

20/26 is 0.0024. Downstream from State Highway 20/

26, the flood plain broadens and is characterized by 

braided channels and remnants of old meander channels. Channel slope is 0.0024 from State Highway 20/

26 to Lincoln Boulevard near INTEC and 0.0031 from 

there to the U.S. Government railroad. The channel 

downstream from the railroad ends in a series of playas 

in the northern part of the INEEL (fig. 1).

Many anthropogenic features in the Big Lost 

River and flood plain affect flood hydraulics and flow. 

The INEEL diversion dam is located in the upstream 

part of the study area. The diversion dam, a low, 

earthen dam, was constructed in 1958 and enlarged in 

1984 to reduce the threat of floods from the Big Lost 

River. Water is diverted southeastward at the dam 

through a diversion channel and is stored in a connected series of spreading areas (figs. 1 and 2). Two 

culverts with control valves regulate flow through the 

dam (culvert site 1 on fig. 2). Immediately downstream 

is another pair of culverts under a discontinued railroad. A complete description of these culverts can be 

found in reports by INEEL (2001) and Kingsford 

(2001).

About 3 mi downstream from the diversion dam 

are the Pioneer weir and canal diversion structures (fig. 

2), concrete structures constructed to divert water to 

canals on both sides of the river. The weir and canals 

were constructed for agricultural interests before the 

inception of the INEEL in 1949 and have been abandoned. The canals have been filled in at their heads and 

in many other places and have been breached in many 

places to prevent water from flowing in them. The 

canal west of the river is about 20 mi long and intersects the Test Reactor Area (TRA) facility. The canal 

east of the river intersects other canals and ends at the 

Big Lost River just before Lincoln Boulevard.

About 6 mi downstream from the INEEL diversion dam, State Highway 20/26 crosses the river and its 

flood plain. A concrete bridge, 61 ft long and 40 ft 

wide, spans the river at an angle of 38 degrees in relation to the river channel (INEEL, 2001; Kingsford, 

2001). The streambed is about 8 ft below the bottom of 

the bridge girders.

Near INTEC, Lincoln Boulevard crosses the Big 

Lost River and its flood plain. Three corrugated, circular, steel culverts, 7.5 ft high and about 150 ft long, 

pass water under Lincoln Boulevard. The upstream and 

downstream ends of the culverts are embedded in concrete headwalls. The channel from Lincoln Boulevard 

to the railroad bridge has been straightened and deepened, and the riverbanks have been raised with excavated materials.

About 1 mi east of Lincoln Boulevard near 

INTEC, a U.S. Government railroad bridge crosses the 

Big Lost River at nearly a right angle. The bridge, 37 ft 

long and 12 ft wide, is supported by concrete abutments and a 2-ft-wide concrete pier in the middle of the 

channel. 

Structures within the river and flood plain downstream from the railroad bridge are beyond the scope 

and area of this study. In the study area, many paved 

and dirt roads crisscross the flood plain. Culverts were 

placed where roads cross over drainage features. 

Kingsford (2001), in a study to document all culverts in 

the study area, located 31 culvert sites. Some sites have 

multiple culverts. For example, site 9, shown on figure 

2, comprises four different-sized corrugated culverts 

underneath a gravel road. Five culvert sites exist on 

Monroe Boulevard (fig. 2). Of the 31 culvert sites, all 

but three are associated with roads. Culverts at those 

three sites convey water through the railroad embankment near INTEC.

Riparian vegetation in the study area is mainly 

sagebrush and grass; vegetation is denser near the river. 

Sparse stands of cottonwood trees grow along the river. 

Most of these trees are now dead because streamflow 

has been infrequent and a wildfire in the study area 

occurred in May 2001.

Acknowledgments

The authors gratefully acknowledge the support of 

Clint O. Kingsford and Jeff A. Lawrence, U.S. Department of Energy at the INEEL, who provided data 

needed for this study and obtained additional data on 

culverts. Appreciation also is extended to Ken Beard, 

INEEL, who obtained horizontal and vertical controls 

for culverts by use of a Global Positioning System 

(GPS) and converted these data for our use.

METHODS OF ANALYSIS

The hydraulic analysis for this study was based on 

an assumption of unobstructed flow; in other words, 

the channel, flood plain, and structures (culverts and 

bridges) were assumed to be free of debris. This 

assumption is probably reasonable for the bridge at 

State Highway 20/26, as this bridge was classified as a 

nonscour, critical bridge site in a statewide bridge 

assessment study (Lotwick Reese, Idaho Transportation Department, oral commun., 2002). Because only 

highway and road bridges were evaluated in the statewide study, the assumption of unobstructed flow might 

not be valid for the other hydraulic structures in the 

study area, as several culverts were completely or partially filled with sediment (Kingsford, 2001). The models used for the present study can simulate discharge 

through hydraulic structures that are partially or completely filled with sediment or debris; however, crosssectional shape must be constant throughout the structure. All elevations were referenced to the National 

Geodetic Vertical Datum of 1929 (NGVD), in feet.

Culverts

Stage-discharge relations for the 31 culvert sites 

were computed using CAP (Fulford, 1998) for a range 

of discharges and stages at each culvert site. CAP is a 

mathematical model that computes discharge through a 

culvert on the basis of the conservation of energy (Bernoulli’s equation) and mass (continuity equation) 

between the approach section and a downstream section. CAP computes headwater elevations by determining flow type from specified combinations of tailwater 

elevation and discharge through a culvert and using 

appropriate equations. The procedures and computations in CAP are based on USGS methods documented 

by Bodhaine (1968), which, in turn, are based on field 

investigations (Carter, 1957) and on laboratory investigations by the USGS, the Bureau of Public Roads, and 

many universities. 

CAP incorporates several simplifying assumptions about culvert flow. CAP assumes ponded conditions only for sluice-gate flow (type 5) and orifice flow 

(type 6). Stage-discharge relations for these two types 

of flow may not be computed accurately because velocity head at the approach section and friction losses 

between the approach section and the culvert inlet are 

ignored in the program. When supercritical conditions 

exist in the approach section, CAP cannot be used 

because flow equations used in CAP are structured for 

solving only subcritical flow. Subcritical flows exist 

throughout the study area, including the vicinity 

around culverts and bridges, as shown in the previous 

USGS model of the Big Lost River (Berenbrock and 

Kjelstrom, 1998); therefore, the use of CAP was 

deemed appropriate for this study. However, CAP cannot simulate flows over roads and (or) embankments 

because equations to simulate these features were not 

included in the program. CAP cannot simulate partially 

or fully blocked flows. Other assumptions are constant 

culvert dimensions and material type throughout its 

length, constant slope (no breaks), no severe adverse 

slopes, and no control valves.

Culvert-geometry data given in reports by INEEL 

(2001) and Kingsford (2001) for the 31 sites were used 

in CAP, and selected data from these reports are presented in table 1. Twenty-six culvert sites were made of 

corrugated metal pipe, three were made of concrete 

pipe, and two were made of multiplate pipe (table 1). 

Most culverts were circular in shape; however, three 

sites were elliptical—site 2 (taller than wide), and sites 

4 and 5 (wider than tall). Also, sites 1, 2, and 6 had 

mitered entrances, whereas all others were considered 

to have vertical headwalls.

Bridges 

The computer model HEC-RAS (Brunner, 2001a, 

Brunner, 2001b) commonly is used to determine the 

water-surface profile in a stream reach for a specified 

discharge. The model also can determine the water-surface profile through bridges, culverts, and in flood 

plains. Version 3.0.1 of the model was used for this 

study to determine stage-discharge relations for bridge 

structures. HEC-RAS computes one-dimensional, 

gradually varied, steady flow in open channels with 

fixed boundaries. The model uses the standard-step 

Methods of Analysis

method (Chow, 1959, p. 265) to determine changes in 

water-surface elevation from a downstream cross section to an upstream cross section by balancing the total 

energy at the sections. In sections that include bridges 

or culverts, HEC-RAS computes the energy loss 

caused by these structures. The model also allows for 

multiple bridge openings and (or) many culverts at a 

site. 

HEC-RAS incorporates several simplifying 

assumptions about flow. HEC-RAS assumes energy is

uniform at cross sections, flow varies gradually from 

one cross section to the next except at hydraulic structures where changes in flow conditions can be quite 

abrupt, and channel boundaries are not moveable. 

HEC-RAS can simulate subcritical, critical, and supercritical flows in a reach. 

For this study, HEC-RAS was used only for 

bridge sites and not for culvert sites. This model is able 

to simulate discharge through culverts but was not used 

for this purpose because culvert hydraulic representation in HEC-RAS is based on design charts and nomographs (Federal Highway Administration, 1965, 1972,

and 1985) instead of actual surface-water equations, as 

in CAP. Ranges of discharge through the bridge and 

tailwater elevation (water-surface elevation at the exit 

section) were simulated in HEC-RAS to determine 

stage-discharge relations. Discharge through the bridge 

may be free-surface flow or pressure flow (unsubmerged or submerged). Road overflow was not represented in the model.

Two bridges, the bridge at State Highway 20/26 

and the U.S. Government railroad bridge near INTEC 

(fig. 2), were analyzed. Cross-section and bridgegeometry data are needed by HEC-RAS for the 

upstream and downstream faces of the bridge opening 

and for the approach and exit sections. Cross-section 

data that were collected from a previous one-dimensional hydraulic model of the Big Lost River and flood 

plain (Berenbrock and Kjelstrom, 1998) were used in

this study. Bridge-geometry data were obtained from 

reports by Berenbrock and Kjelstrom (1998), INEEL 

(2001), and Kingsford (2001), and selected data from 

these reports are presented in table 2. Roughness coefficients (Manning’s n) for the channel and flood plain 

needed by HEC-RAS also were obtained from Berenbrock and Kjelstrom’s report (1998) and are presented 

in table 2. 

RESULTS OF CULVERT ANALYSES

Discharge through the culverts, as computed by 

CAP, ranged from about 0 ft3

/s to as much discharge as 

could be conveyed, and tailwater elevations ranged 

from about 0 to 30 ft above the outlet elevation. If a site 

comprised multiple culverts, each culvert was analyzed 

separately. At site 6, for example, each of the three culverts was analyzed separately. Total discharge at site 6 

can be obtained by adding results from the three culverts. One of the two culverts at site 21 was not analyzed because its characteristics and dimensions could 

not be determined (C.O. Kingsford, written commun., 

2002).

Results from CAP for the 31 culvert sites are 

shown in appendix 1 (back of report). For each culvert, 

the outlet invert was set to zero elevation for ease in 

modeling and displaying results. Corrected elevations 

can be obtained by adding the datum corrections provided in the appendix to headwater and tailwater elevations. Stage-discharge relations for the 4-ft-diameter 

culvert at site 8 are shown in figure 3 as an example. 

Headwater elevations and discharge through the culvert 

are represented by the ordinate and abscissa axes, 

respectively, and tailwater elevations are represented 

by a series of curved isopleths. The lowest isopleth 

defines the lowest limit for tailwater conditions set at 

about 0 ft. No relations are computed below the lowest 

isopleth. Another stage-discharge relation example for 

the 1.5-ft culvert at site 22 is shown in figure 4. Figures 

3 and 4 are similar (isopleths increase as discharges 

increase), except that the maximum discharge through 

the culvert at site 22 is about 50 ft3

/s and, at site 8, is 

about 350 ft3/s. The main reason for this difference is 

the difference in diameter of the culverts.

The stage-discharge relation of headwater elevation, tailwater elevation, and discharge is unique for 

each culvert. Graphs similar to figures 3 and 4 can be 

developed for all other culverts in the study area using 

the results in appendix 1. These results, in turn, can be 

incorporated into numerical surface-water-flow models 

such as TRIM2D (Ostenaa and others, 1999) to simulate the effects of these culverts on flood flows in a continuous reach of the Big Lost River.

RESULTS OF BRIDGE ANALYSES

Discharge through the two bridges as computed 

by HEC-RAS ranged from nearly 0 to 7,000 ft3/s, and 

tailwater elevations ranged from nearly 0 to 30 ft above 

the streambed on the downstream cross section of the 

bridge.

Results from HEC-RAS for the two bridges are 

given in appendix 2 (back of report). For each bridge, 

the lowest elevation on the downstream cross section of 

the bridge was set to zero for ease in modeling and displaying results. Corrected elevations can be obtained 

by adding the datum corrections provided in the appendix to headwater and tailwater elevations. Stage-discharge relations for site 7 (U.S. Government railroad 

bridge near INTEC) are shown in figure 5 as an example. If water-surface elevation through the bridge is 

below 7.3 ft (distance between streambed and lowest 

bridge girder) or at an elevation of 4,902.6 ft, discharge 

is considered to be free-surface flow. But when watersurface elevation is equal to or greater than 7.3 ft, discharge is considered pressurized through the bridge. 

For discharges equal to and greater than 2,000 ft3

/s, the 

lowest isopleth is about 7.3 ft; for discharges less than 

2,000 ft3

/s, the lowest isopleth decreases to 0 ft.

Stage-discharge relations for the Highway 20/26 

bridge site were similar to those for the railroad 

bridge—tailwater elevations increase as headwater elevations and discharge through the bridge increase. 

Stage-discharge relations for each bridge are different 

from one another because of the uniqueness of the 

bridges and stream geometries. These results (appendix 

2) can be incorporated into numerical surface-waterflow models such as TRIM2D (Ostenaa and others, 

1999) to simulate the effects of these bridges on flood 

flows.

LIMITATIONS

The CAP and HEC-RAS computer models can be 

useful tools for determining stage-discharge relations 

for culverts and bridges. However, results presented in 

this report are based on models which, in turn, are 

based on theoretical and laboratory experiments. To 

verify stage-discharge relations for each structure, discharge measurements are needed under a variety of disLimitations

charges and flow regimes (unsubmerged, or free-surface flow, and submerged, or pressurized flow). Headwater and tailwater elevations also must be measured at 

the time of the discharge measurement. 

To use the CAP and HEC-RAS models, several 

assumptions must be satisfied as previously discussed. 

Although most of the assumptions for this study were 

satisfied, the assumption that culverts and bridges are 

free of sediment and debris is probably not representative of actual field conditions in the study area during 

overbank flows. INEEL (2001) and Kingsford (2001) 

noted that many of the culverts were partially filled 

with sediment and several culverts were completely 

filled with sediment. Because sediment might not be 

completely removed during flooding, model-simulated 

discharges through the hydraulic structures might be 

greater than would be experienced under actual conditions.
