DETERMINATION OF INFILTRATION AND PERCOLATION 

RATES ALONG A REACH OF THE SANTA FE RIVER NEAR 

LA BAJADA, NEW MEXICO

By Carole L. Thomas, Amy E. Stewart, and Jim Constantz

ABSTRACT

Two methods, one a surface-water method 

and the second a ground-water method, were used 

to determine infiltration and percolation rates 

along a 2.5-kilometer reach of the Santa Fe River 

near La Bajada, New Mexico. The surface-water 

method uses streamflow measurements and their 

differences along a stream reach, streamflow-loss 

rates, stream surface area, and evaporation rates to 

determine infiltration rates. The ground-water 

method uses heat as a tracer to monitor percolation 

through shallow streambed sediments.

Data collection began in October 1996 and 

continued through December 1997. During that 

period the stream reach was instrumented with 

three streamflow gages, and temperature profiles 

were monitored from the stream-sediment 

interface to about 3 meters below the streambed at 

four sites along the reach.

Infiltration is the downward flow of water 

through the stream-sediment interface. Infiltration 

rates ranged from 92 to 267 millimeters per day for 

an intense measurement period during June 26-28, 

1997, and from 69 to 256 millimeters per day 

during September 27-October 6,1997. 

Investigators calculated infiltration rates from 

streamflow loss, stream surface-area 

measurements, and evaporation-rate estimates. 

Infiltration rates may be affected by unmeasured 

irrigation-return flow in the study reach. Although 

the amount of irrigation-return flow was none to 

very small, it may result in underestimation of 

infiltration rates. The infiltration portion of 

streamflow loss was much greater than the 

evaporation portion. Infiltration accounted for

about 92 to 98 percent of streamflow loss. 

Evaporation-rate estimates ranged from 3.4 to 7.6 

millimeters per day based on pan-evaporation data 

collected at Cochiti Dam, New Mexico, and 

accounted for about 2 to 8 percent of streamflow 

loss.

Percolation is the movement of water 

through saturated or unsaturated sediments below 

the stream-sediment interface. Percolation rates 

ranged from 40 to 109 millimeters per day during 

June 26-28, 1997. Percolation rates were not 

calculated for the September 27-October 6,1997, 

period because a late summer flood removed the 

temperature sensors from the streambed. 

Investigators used a heat-and-water flow model, 

VS2DH (variably saturated, two-dimensional 

heat), to calculate near-surface streambed 

infiltration and percolation rates from 

temperatures measured in the stream and 

streambed.

Near the stream-sediment interface, 

infiltration and percolation rates are comparable. 

Comparison of infiltration and percolation rates 

showed that infiltration rates were greater than 

percolation rates. The method used to calculate 

infiltration rates accounted for net loss or gain over 

the entire stream reach, whereas the method used 

to calculate percolation was dependent on point 

measurements and, as applied in this study, 

neglected the nonvertical component of heat and 

water fluxes. In general, using the ground-water 

method was less labor intensive than making a 

series of streamflow measurements and relied on 

temperature, an easily measured property. The 

ground-water method also eliminated the 

difficulty of measuring or estimating evaporation
from the water surface and was therefore more 

direct. Both methods are difficult to use during 

periods of flood flow. The ground-water method 

has problems with the thermocouple-wire 

temperature sensors washing out during flood 

events. The surface-water method often cannot be 

used because of safety concerns for personnel 

making wading streamflow measurements.

INTRODUCTION

Infiltration and percolation are important in the 

Middle Rio Grande Basin because they affect recharge 

to ground water. The amount of surface recharge to 

ground water largely depends on the quantity of water 

that infiltrates through porous sediment and percolates 

to the water table. Infiltration is the downward flow of 

water through the stream-sediment interface. 

Percolation is the movement of water through saturated 

or unsaturated sediments below the stream-sediment 

interface.

Near the stream-sediment interface, infiltration 

and percolation rates are comparable. At depth, the 

percolation rate varies from the infiltration rate because 

of divergence of flow, storage in the unsaturated zone, 

and capture by plant roots that move water to the air as 

transpiration.

Historically, surface-water methods have been 

used to determine infiltration, but they have several 

disadvantages, especially in semiarid environments. 

Stream gage installation and operation are expensive, 

the accuracy of using stream stage and a rating curve to 

calculate flow is not constant because of the 

unconsolidated channel typical of semiarid 

environments, and streamflow measurements used to 

develop a stream-stage relation and to determine gains 

and losses along a stream are labor intensive. Thus, 

alternative methods are needed, and a ground-water 

method of monitoring vertical temperature profiles 

under streambeds has promise as a direct and more 

economical alternative to traditional methods. An 

investigation of infiltration and percolation along the 

Santa Fe River was undertaken as part of a study of the 

Middle Rio Grande Basin by the U.S. Geological 

Survey (USGS).

Purpose and Scope

This report presents infiltration and percolation 

rates determined from data collected along a 2.5- 

kilometer (km) reach of the Santa Fe River near La 

Bajada, New Mexico. The data, collected during 1996 

and 1997, include streamflow, stream surface area, 

evaporation rate, and vertical streambed temperature. 

Streamflow gages installed at three sites along the 

reach recorded 15-minute stage data from October 1, 

1996, through December 3, 1997. USGS personnel 

made current-meter measurements of streamflow along 

the reach during the data-collection period. Stream 

surface-area measurements were made and related to 

stage. To determine vertical streambed temperature 

profiles, thermocouple nests were installed in the 

streambed to a depth of 3 meters (m) and temperature 

data were collected at 10-minute intervals. Infiltration 

rates were calculated from streamflow-loss data, 

stream surface-area data, and evaporation-rate 

estimates. Percolation rates were calculated from 

vertical streambed temperature-profile data using the 

streambed temperature-profile method (Constantz and 

Thomas, 1996; 1997) and the variably saturated, twodimensional, heat (VS2DH), computer-model method 

(Healy and Ronan, 1996).

DESCRIPTION OF THE STUDY AREA

Middle Rio Grande Basin

The Middle Rio Grande Basin (fig. 1) is one of 

several structural basins of the Rio Grande Rift that 

extend through New Mexico. Basin floor, land-surface 

altitudes range from about 1,460 m above sea level in 

the south to more than 1,980 m above sea level in the 

north (Thorn and others, 1993). Mountains form the 

basin margins along the northern and eastern borders, 

rising dramatically to more than 3,000 m above sea 

level. Bartolino (1997) defined the hydrologic basin as 

the area within the Rio Grande Valley extending from 

Cochiti Dam downstream to the community of San 

Acacia (fig. 1), approximately 7,770 square kilometers. 

Population in the basin increased from 314,900 to 

563,600 between 1970 and 1990 (Thorn and others, 

1993). The Albuquerque metropolitan area is the main 

population center in the basin, with about 89 percent of 

the basin's 1990 population (Thorn and others, 1993).

The New Mexico Office of the State Engineer 

has regulatory authority over water resources in this 

basin and has declared the Middle Rio Grande Basin a 

"critical basin." "Critical basin" declaration means that 

the ground-water basin is expected to experience rapid 

economic and population growth and that technical 

information regarding the available water supply is less 

than adequate (New Mexico Office of the State 

Engineer, written commun., 1995). Water supply in the 

Middle Rio Grande Basin is largely from ground-water 

sources delivered by domestic and public-supply wells. 

The Santa Fe Group aquifer system is the main 

geologic source of ground water. Thorn and others 

(1993) considered the aquifer system to be composed 

of Santa Fe Group and post-Santa Fe Group valley and 

basin-fill deposits. The most productive lithologies are 

the axial-channel deposits of the ancestral Rio Grande 

and, to a lesser extent, piedmont-slope and alluvial-fan 

deposits (Thorn and others, 1993). Thorn and others 

reported declining water levels of 43 m from 1960 to 

1992 in the east Albuquerque area from pumping, fault 

barriers, and the limited extent of the axial-channel 

deposits. Surface water supplies most of the 

agricultural water-related needs in the basin and is 

stored in upstream reservoirs and then delivered by the 

Rio Grande to the associated system of canals, ditches, 

and laterals.

Recently, Hawley and Haase (1992), Thorn and 

others (1993), Hawley and others (1995), and

Tiedeman and others (1998) have described the 

geology and hydrology of the basin. The following 

description of the depositional history, lithology, and 

thickness of the basin deposits is condensed from these 

authors. Rock units in the basin are primarily 

sedimentary and include pre-Santa Fe Group deposits, 

Santa Fe Group deposits, and post-Santa Fe Group 

deposits. The Santa Fe Group is the predominant basin 

deposit, reaching a thickness greater than 4,270 m in 

the center of the basin. The Santa Fe Group was 

deposited from Oligocene through early Pleistocene 

times, about 30 million years ago to 5 million years 

ago, and contains piedmont-slope, eolian, playa, and 

fluvial deposits. The post-Santa Fe Group was 

deposited from 1 million years ago to the present and 

contains channel and flood-plain alluvial deposits 

about 24 m thick and some volcanic flows in small 

areas.

Climate in the Middle Rio Grande Basin is 

characterized as semiarid. The basin has scant 

precipitation, abundant sunshine, low relative 

humidity, and a wide seasonal range of temperatures. 

At long-term weather stations within the basin, average 

annual precipitation is about 20 to 25 centimeters (cm). 

Average annual temperature in the basin ranges from 

about 54 to 58 °F. The mean daily low temperature in 

the basin is about 34 °F in January, and the mean daily 

high temperature is about 77 °F in July (U.S. 

Department of Commerce, 1997). The period of record 

is 1961-90.

Santa Fe River Site

The Santa Fe River has certain characteristics 

that make it a desirable study site. Effluent from the 

Santa Fe Wastewater Treatment Plant causes this 

naturally ephemeral stream to be perennial for some 

distance downstream from the treatment plant, thus 

increasing the opportunity to collect flow data. The 

Santa Fe River passes through a deep canyon 

downstream from the treatment plant and onto a gently 

sloping alluvial fan before joining the Rio Grande. In 

the La Bajada area, the stream channel is of interest as 

an area of potential recharge to the ground-water 

system.

The reach of the Santa Fe River selected for this 

study starts at the USGS gaging station Santa Fe River 

above Cochiti Lake, New Mexico (08317200) (fig. 1).

Downstream from this gaging station, ground water 

discharges to the stream only in the first 100 to 500 m 

of the study reach, where bedrock is close to the ground 

surface. The thickness of alluvial sediments then 

increases rapidly and the stream loses water for the 

remaining 2 km of the study reach. Surface-water flow 

often ceases a short distance downstream from the 

study reach.

Streamflow data are available for the Santa Fe 

River above Cochiti Lake gaging station from March 

1970 to the present (1998) (fig. 1). The daily mean flow 

at this station for water years 1970-97 is 11.7 cubic feet 

per second (ft3/s) or 0.33 cubic meter per second 

(m3/s). The daily mean flow for water year 1997 ranged 

from 2.8 to 140 ft3/s (0.08 to 3.96 m3/s); 90 percent of 

daily mean flow values were less than or equal to 

19 ft3/s (0.54 m3/s). Flows greater than 19 ft3/s (0.54 

m3/s) generally are a response to storm events or to 

May-June releases from an upstream reservoir. Daily 

flow at this station is generally variable and has a 

pattern of a minimum in the late afternoon and a 

maximum during the night to early morning hours. 

This diurnal pattern in Streamflow is due to several 

factors, including the release pattern from the sewage 

treatment plant; changes in water viscosity with 

temperature, which affect streambed hydraulic 

conductivity and consequently the infiltration rate 

(Constantz and others, 1994); and evapotranspiration 

losses.

The study reach extends downstream from the 

USGS gaging station for approximately 2.5 km to 

include two new Streamflow gages installed in 

September 1996 to allow collection of Streamflow data 

for two contiguous channel reaches. The new stations 

are Santa Fe River above La Bajada, New Mexico 

(08317203), and Santa Fe River below La Bajada, New 

Mexico (08317207) (fig. 1).

DETERMINATION OF INFILTRATION 

RATES

Infiltration-rate estimates are based on 

Streamflow loss, stream surface area, and estimated 

evaporation rates. Streamflow loss divided by stream 

surface area gives a streamflow-loss rate. The 

evaporation rate subtracted from the streamflow-loss 

rate gives an infiltration rate.

Streamflow-Loss Rate

Streamflow loss is defined as the reduction in 

Streamflow between an upstream and a downstream 

measuring point for a given time period. Streamflow 

differences must be greater than measurement errors to 

achieve accuracy. If the magnitude of the Streamflow 

difference between any two measurement points is 

small, then errors in the Streamflow measurements can 

mask any Streamflow loss. Therefore, identifying a 

reach with no intervening inflows or outflows, and 

where the Streamflow difference is large relative to 

potential measurement errors, is critical for 

maximizing accuracy.

In this study, an initial streamflow-measurement 

survey was made to locate losing stream reaches and to 

determine whether Streamflow losses would be large 

enough to exceed measurement errors. Of the reaches 

surveyed, the Santa Fe River near La Bajada was 

chosen as the reach that best fit the criteria. Even so, 

this reach was less than ideal, and periods of record had 

to be carefully selected and analyzed. A favorable 

aspect of this reach was the perennial flow resulting 

from upstream wastewater treatment plant discharge. 

The numerous days of flow increased the likelihood 

that a suitable period of record could be chosen to 

calculate Streamflow loss. An unfavorable aspect of the 

reach was unmeasured irrigation-return flow. A 

headgate located about 0.7 km upstream from the study 

reach allowed diversions for irrigation. A canal carried 

water to irrigate about 160 hectares of farmland at the 

village of La Bajada. Gates in the main canal allowed 

irrigation water to return to the Santa Fe River at two 

locations between streamflow-gaging stations 

08317203 and 08317207 (fig. 2). This return flow was 

not measured and introduced an error in the calculation 

of Streamflow losses between stations 08317203 and 

08317207. The Streamflow loss is underestimated by 

the amount of this unmeasured return flow.

Stream-stage data were collected at 15-minute 

intervals and current-meter Streamflow measurements 

(approximately monthly) were made from October 1, 

1996, through December 3, 1997, at the gaging 

stations. For each station, daily mean Streamflow 

values were computed using stage-streamflow rating 

curves and shifts (Ortiz and others, 1998, p. 11-12). 

Tables 1-3 list daily mean Streamflow values at the 

three stations from October 1, 1996, through 

December 3, 1997 (all tables are in the back of the 

report). An unsuccessful attempt was made to calculate 

streamflow-loss rates from the daily mean flow data in 

tables 1-3. The data are given for reference purposes 

only because they are not published elsewhere.

Figure 2. Relation of reaches to irrigation turnouts and returns.
To improve accuracy of the stage-streamflow 

relations, intensive current-meter streamflow 

measurements were made for several data-collection 

periods in 1997. Current-meter measurements were 

made from early morning until late afternoon at each of 

the three streamflow-gaging stations, 08317200, 

08317203, and 08317207, on June 26,1997, and again 

during September 30-October 2, 1997 (table 4). 

Because flow varies throughout the day at these 

stations, measuring from early morning until late 

afternoon allowed for a range of stage and streamflow. 

Stage-streamflow relations were then determined by 

regression for the June and September-October 1997 

time periods.

Stage-streamflow relations for a sand and gravel 

channel, such as this one, change with channel 

morphology. Based on additional stage, streamflow, 

and precipitation data that indicate changes in channel 

morphology, the relation established for June 26 was 

used for data collected from June 26 through June 28, 

1997, and the relation established for September 30 

through October 2, 1997, was used for data collected 

from September 27 through October 6, 1997. The 

relation allows calculation of streamflow from 15- 

minute stage data recorded at the streamflow-gaging 

station. Fifteen-minute stage data input to the stagestreamflow regression equation determined streamflow. 

Stage data that were greater or less than that measured 

during the time period covered by the relation were not 

used because of the possible inaccuracies involved in 

extrapolation of the relation.

Streamflow at the gaging stations is variable. The 

pattern of a daily minimum in the late afternoon and a 

daily maximum during the night to early morning 

hours of a 24-hour cycle requires a travel-time 

adjustment when using instantaneous streamflow 

values. The travel time is the time water takes to travel 

from one gaging station to the next and is dependent on 

the velocity of the water and the distance between 

gaging stations. Water velocity changes with location 

in the cross section, longitudinally along the stream, 

and with time at a specific location. For example, 

table 4 shows that the mean, cross-sectional velocities 

for streamflow measurements made at stations 

08317200,08317203, and 08317207 ranged from 0.81 

to 2.16 feet per second. The method used to determine 

the travel-time adjustment was curve matching. The 

time shift necessary to match the peaks and valleys of 

the hydrographs at successive, downstream gaging 

stations is the travel time. Figure 3 is an overlaid plot of 

streamflow data for June 26-July 3, 1997, showing the

match in hydrographs that determined the time of travel 

from station 08317200 to 08317203, from station 

08317203 to 08317207, and from station 08317200 to 

08317207 to be 15, 30, and 45 minutes, respectively. 

Curve matching for other periods of record that were 

analyzed yielded similar results; therefore, the traveltime adjustment used for data analysis in this report 

was 15, 30, and 45 minutes from station 08317200 to 

08317203, from 08317203 to 08317207, and from 

08317200 to 08317207, respectively.

Streamflow loss between stations 08317200 and 

08317203 was small to negligible; more streamflow 

loss appeared to occur between stations 08317203 and 

08317207. Streamflow-loss estimates from station 

08317200 to station 08317207 are shown in table 5. In 

table 5, for example, streamflow at the downstream 

station subtracted from streamflow at the upstream 

station determined the streamflow loss after adjustment 

for the appropriate travel time. Using station 08317200 

as the upstream station and 08317207 as the 

downstream station, 45 minutes is the appropriate 

travel-time adjustment. For example, streamflow at 

station 08317200 at 11:00 on June 26, 1997 (8.32 

ft3/s), minus streamflow at station 08317207 at 11:45 

on June 26, 1997 (6.36 ft3/s), equals streamflow loss 

(1.96ft3/s)(table5).

The average streamflow loss for the June 26-28, 

1997, period was 1.03 ft3/s (0.029 m3/s) with a 

standard deviation of 0.60 ft3/s (0.017 m3/s), median of 

1.15 ft3/s (0.033 m3/s), mode of 1.14 ft3/s (0.032 m3/s), 

and range of-0.23 to 2.75 ft3/s (-0.007 to 0.078 m3/s). 

The average streamflow loss for the September 27- 

October 6, 1997, period was 0.84 ft3/s (0.024 m3/s) 

with a standard deviation of 0.55 ft3/s (0.016 m3/s), 

median of 0.90 ft3/s (0.025 m3/s), mode of 1.25 fWs 

(0.035 m3/s), and range of-0.42 to 2.17 ft3/s (-0.012 to 

0.061 m3/s).

Stream Surface Area

The stream surface area is needed to compute 

infiltration rates from streamflow losses between 

measuring locations. To determine the surface area of 

the stream, stream width was measured at 100-m 

intervals along the 2,500-m study reach on June 26-27, 

1997. Measurements were started at approximately 

10:00, 12:00, 14:00, 16:00, and 18:00 hours on June 

26, 1997, and at 08:00 on June 27, 1997. Width 

measurements were progressive from upstream to 

downstream, starting at the aforementioned times.

STREAMFLOW, IN LITERS PER SECOND
Width measurements multiplied by length 

(100 m) equaled rectangular surface areas along the 

studied stream reach. The sum of the 25 rectangular 

surface areas equaled the surface area of the stream 

reach (table 6).

Evaporation Rate

The evaporation rate was estimated from the 

pan-evaporation rate at Cochiti Dam, located about 12 

km northwest of the study area (U.S. Department of 

Commerce, 1997, p. 30-31). The pan-evaporation rate 

at Cochiti Dam, multiplied by a pan coefficient of 0.7 

(Linsley and others, 1982, p. 152), was assumed to be 

a good estimate of the evaporation rate from the stream 

surface in the study reach (table 7).

Infiltration Rate

Instantaneous streamflow-loss estimates, based 

on data collected once every 15 minutes (table 5), were 

divided by stream surface area adjusted every 15 

minutes for the study reach. The 15-minute stream 

surface area was calculated using a regression equation 

established for stage and stream surface area. The stage 

used in the regression equation was the mean stage at 

station 08317203. Streamflow loss divided by stream 

surface area yields a streamflow-loss rate (table 5) per 

unit area that can be partitioned into infiltration and 

evaporation.

The average infiltration rate, per unit area per 

day, ranged from 92 to 267 millimeters per day 

(mm/day) for June 26-28, 1997, and from 69 to 256 

mm/day for September 27-October 6, 1997 (table 8). 

Underestimation of streamflow loss by an amount 

equal to unmeasured irrigation-return flow in the study 

reach may result in underestimation of infiltration 

rates. Table 8 shows that the infiltration portion of 

streamflow loss was much greater than the evaporation 

portion. Infiltration accounted for about 92-98 percent 

of streamflow loss, whereas evaporation accounted for 

about 2-8 percent of streamflow loss (table 8).

DETERMINATION OF PERCOLATION 

RATES

Heat was used as a tracer to monitor streambed 

percolation rates. The temporal distribution of

streambed temperatures with depth was input to a 

USGS simulation model. The model, VS2DH (Healy 

and Ronan, 1996), was used to simulate heat and water 

transport in variably saturated sediments beneath the 

streambed.

The stress modeled in the system was the 

temperature difference with depth. The top thermal 

boundary condition varied in time (diurnally). The 

upper hydraulic boundary condition (river stage) was 

kept at a constant value. The upper thermal boundary 

condition, as simulated, was identical to data collected 

at 10-minute intervals at the sites for selected time 

periods.

Model-simulated temperatures were compared 

with measured temperatures until the best match with 

depth was obtained. For this match, the model 

percolation rate, the product of hydraulic conductivity 

and head gradient, is calculated to estimate the 

percolation rate at the selected site. The procedure is an 

application of the model to simulate a percolation rate, 

not a calibration or verification of the model for the 

Santa Fe River sites.

Streambed Temperature-Profile Data

Four temperature-profile sites were selected 

along the 2.5-km study reach. Three sites were 

established at the streamflow-gaging stations and the 

fourth site was located halfway between the lower two 

streamflow-gaging stations (fig. 1). A Geoprobe soilprobing machine, Model 8-mu, which is a truckmounted hydraulic ram/percussion hammer, was used 

to install thermocouple wires vertically into the 

streambed. The pickup truck was positioned in the 

stream, the drill rod was driven approximately 3 m into 

the streambed, and thermocouple wires were inserted 

down the drill rod before removal of the rod from the 

streambed. At each site, six thermocouple wires were 

installed at approximately 0, 0.4, 0.7, 1,2, and 3 m 

below the streambed near the center of the stream. 

Temperature was recorded at 10-minute intervals by 

data loggers in shelters on the right streambank from 

September 1996 through October 1997. The 

temperature-profile data-collection sites are referred to 

as thermocouple nest (TCN) sites TCN1, TCN2, 

TCN3, and TCN4 (fig. 1)
Figure 4 depicts the streamflow and stream 

temperature pattern for most months of water year 

1997. These types of annual patterns are common for 

locations that experience significant seasonal 

variations in precipitation and temperature.

Figure 5 depicts the streambed temperature 

profiles for October 18,1996, through October 8,1997, 

at approximately 0.4,0.6, and 3 m (other depths are not 

shown in the figure for clarity of individual temperature 

curves). Note that the amplitude of the diurnal variation 

in the shallow streambed temperatures is noticeably 

greater in the spring than in other times of the year. 

With the assumption that sediments beneath the 

streambed are saturated, this suggests maximum water 

and heat flow into the streambed during the spring.

Figure 6 compares streamflow at each stream 

gage and stream temperature at site TCN2 for June 26- 

July 2, 1997 (the period when streambed infiltration 

and percolation rates were compared). The pattern of 

minimum streamflow and maximum stream 

temperature in early afternoon is common in small to 

moderately sized streams for several reasons. Solar 

warming causes maximum temperature in the 

afternoon hours, and the viscosity of water decreases 

with temperature, causing infiltration rates to be 

greatest in the afternoon hours (Constant/, 1998). For 

this reach of the Santa Fe River, however, the diurnal 

pattern of discharge from the wastewater treatment 

plant, about 18 km upstream from the upper streamflow 

gage, is a primary factor in the observed diurnal pattern 

of streamflow.

Percolation Rate

Santa Fe River percolation rates were simulated 

using VS2DH, assuming vertically downward flow 

through homogeneous, saturated sediments beneath the 

streambed. The model simulated a 5-m vertical section 

in the channel that is 10 cm wide. A variable grid was 

developed, with node spacing ranging from 2 mm at the 

surface to half a meter at the bottom. Thermal 

conductivity and heat capacity were set at 2 watts per 

meter per degrees Celsius (°C) and 3 x 106 joules per 

cubic meter per °C, respectively. The simulation was 

designed to match subsurface temperatures with 

vertical temperature profiles measured at several sites 

along the Santa Fe River study reach.

At each location, stream temperature and stage 

were used as the upper model boundary and supplied 

water and heat to the sediments below the stream. A 10-

cm stage was assigned for sites TCN2 and TCN4, a 

representative stage for these sites. Site TCN3 had 

different channel morphology; therefore, a 20-cm stage 

was representative for this site. Site TCN1 was not 

simulated with deeper water because of problems in 

data collection. Initial thermal conditions for the 

simulation were taken from actual measurements, with 

a linear interpolation between data points. Hydraulic 

conductivities and the bottom head boundary condition 

(and therefore, the hydraulic gradient) were determined 

according to the best subsurface thermal matches.

As representative of the three locations, the 

measured stream temperature (0.0-m depth 

thermocouple) and streambed temperatures for June 

26-July 2, 1997, are shown in figure 7 for site TCN2 

(results for sites TCN3 and TCN4 are similar). 

Simulation results using VS2DH were matched to 

these measured results for all three sites to estimate 

streambed percolation rates.

The shallowest thermal data were matched to the 

corresponding depth in the model as well as matched to 

the next shallowest depths in separate simulations. 

Using the shallowest depth resulted in better 

temperature matches because of the 

multidimensionality of the flow at depth. A onedimensional model can accurately describe percolation 

rates at depth only if ground-water flow moves only 

vertically. However, in many stream environments, 

ground-water flow deviates from vertical flow paths at 

depths. A solution for the percolation rate was obtained 

for the shallowest depths for a given set of conditions 

in the model. Figures 8, 9, and 10 show the simulated 

and measured streambed temperatures at shallow 

depths at sites TCN2, TCN3, and TCN4, respectively. 

Once a match was made, heat and water flux into the 

top node of the model were calculated for each location 

to determine a streambed percolation rate. Table 9 lists 

the calculated streambed percolation rates at each 

indicated depth for each site.

COMPARISON OF INFILTRATION AND 

PERCOLATION RATES

The estimates of infiltration rates derived using 

the surface-water method ranged from 92 to 267 

mm/day for June 26-28, 1997. For the same time 

period, the estimates of percolation rates derived using 

the ground-water method ranged from 40 to 109 

mm/day.

Several issues needed to be considered before 

evaluating the degree of agreement between estimated 

infiltration and percolation rates. Estimates of 

percolation were based on only three locations along 

the 2.5-km stream reach, whereas estimates of 

infiltration were based on net infiltration rates averaged 

over the entire 2.5-km stream reach. Three 

measurement points may be insufficient to represent an 

average percolation rate for the entire reach. Of more 

significance, percolation rates from vertical 

temperature profiles do not measure the nonvertical 

component of heat and water fluxes that may occur 

along the edges of the stream. Nonvertical flow is 

measured by net streamflow loss, but not by vertical 

temperature profiles. Thus, measurements of 

streambed percolation are expected to be less than 

measurements of streambed infiltration for streams 

with a significant nonvertical component to streamflow 

loss. Streams that are hydraulically connected to the 

water table have a greater nonvertical component of 

flow than streams that are not hydraulically connected 

to the water table. The La Bajada reach of the Santa Fe 

River was hydraulically connected to the water table 

during June 1997, thus having a significant nonvertical 

component of streambed loss during the period of 

methods comparison. Therefore, estimates of 

streambed percolation beneath the center of the stream 

channel can be expected to be less than estimates of 

streambed infiltration averaged across the entire 

channel.

Infiltration-rate estimates are affected by 

inaccuracies related to the use of stage-streamflow 

relations and measurement errors; for this reason, the 

use of stage-streamflow relations proved to be too 

inaccurate to determine streamflow losses for the 

period of record. Extrapolation of a stage-streamflow 

relation much beyond the series of current-meter 

streamflow measurements used to develop the relation 

showed that the relation was changing, probably 

because of the sandy nature of the streambed. The 

difference in streamflow between stations was of the 

same magnitude as errors from the stage-streamflow 

relation. To use stage-streamflow relations, the 

streamflow loss between any two measurement points 

may need to be greater than 10-15 percent, which is the 

estimated error for records at gaging stations rated 

good to fair (Ortiz and others, 1998, p. 15).

Infiltration and percolation during flooding are 

of great interest because of the potential for recharge to 

be large. In this study reach, high-water marks show

that the stream overflows its banks and the surficial area 

for infiltration increases greatly. If a secure method of 

anchoring temperature sensors within the streambed 

could be devised, then the ground-water method could 

be used to gather temperature data that could then be 

used, with modeling, to determine percolation rates. 

However, flood pulses washed out the thermocouple 

temperature sensors that were installed in the 

streambed during this study. Wading streamflow 

measurements are generally too dangerous to be made 

during flood events.

In general, the ground-water method may be 

preferred over the surface-water method when 

nonvertical flow components are negligible. The 

ground-water method has several advantages over the 

surface-water method. It is less labor intensive than 

streamflow measurements, relying on temperature 

data, an easily measured property. Temperature 

measurements can be collected frequently and 

automatically through the use of a data logger. The 

ground-water method also eliminates the difficulty of 

measuring or estimating evaporation from the water 

surface and is therefore a more direct method for 

estimating percolation below the streambed.

AMD ©©MCLUSDOMS

A 2.5-km reach of the Santa Fe River near La 

Bajada, New Mexico, was intensively monitored 

during 1996 and 1997. Two methods, one a surfacewater method and the second a ground-water method, 

were used to determine infiltration and percolation 

rates. Infiltration and percolation are important in the 

Middle Rio Grande Basin because they affect recharge 

to ground water. The amount of surface recharge to 

ground water largely depends on the quantity of water 

that infiltrates through porous sediment and percolates 

to the water table.

Infiltration rates were determined using a 

surface-water method that is based on streamflow 

measurements and their differences along a stream 

reach, streamflow-loss rates, stream surface area, and 

evaporation rates. The infiltration rate per unit area per 

day, determined from streamflow loss after adjustment 

for evaporation from the stream surface, ranged from 

92 to 267 mm/day for June 26-28,1997, and from 69 to 

256 mm/day for September 27-October 6, 1997. 

Underestimation of streamflow loss by an amount 

equal to unmeasured irrigation-return flow in the study
reach may result in underestimation of infiltration 

rates.

The infiltration portion of streamflow loss was 

much greater than the evaporation portion. Infiltration 

accounted for 92-98 percent of strearnflow loss; 

evaporation accounted for 2-8 percent of strearnflow 

loss.

During June 26-28, 1997, near-surface 

percolation rates were calculated and compared to 

infiltration rates. Percolation rates were determined 

using a ground-water method that uses heat as a tracer 

to monitor percolation through shallow streambed 

sediments. Percolation rates ranged from 40 to 109 

mm/day. The agreement between these percolation 

rates and the infiltration rates of 92 to 267 mm/day is 

good considering (1) percolation rates were based on 

only three locations along the entire stream reach and 

(2) percolation rates derived from vertical temperature 

profiles do not include the nonvertical component of 

heat and water fluxes.

In conclusion, the ground-water method has 

some advantages over the surface-water method when 

nonvertical flow components are negligible. It is less 

labor intensive than strearnflow measurements, relying 

on temperature data, an easily measured property. The 

ground-water method also eliminates the difficulty of 

measuring or estimating evaporation from the water 

surface.

LOCATION.--Lat 35°32'49", long 106°13'41", in NW1 /4 sec. 8, T. 15 N. , R. 7 E., Santa Fe County, Hydrologic Unit 

13020201 in Mesita de Juana Lopez Grant, on right bank at foot of La Bajada Hill, 5.0 miles upstream from Cochiti 

Dam, 6.3 miles east of Pena Blanca, and at mile 7.9.

DRAINAGE AREA.--231 square miles.

WATER-DISCHARGE RECORDS

PERIOD OF RECORD.--March 1970 to current year.

GAGE.--Water-stage recorder and concrete control. Elevation of gage is 5,505 feet above National Geodetic Vertical 

Datum of 1929, from topographic map.

REMARKS.--Water-discharge records good except for estimated daily discharges, which are poor. Surface- and groundwater diversions and returns for municipal supply of City of Santa Fe in upper part of basin. Diversions for 

irrigation of about 400 acres upstream from station. See tabulation below for the results of discharge 

measurements made during year at point adjacent to gage of an unnamed ditch on right bank, which diverts water 

0.4 mile upstream and bypasses gage; ditch flow not included in record. Lowest flow for period of record, no 

flow July 16-18, 1971.
