Trace metals in surface water and stream sediments of Healy and Lignite Creek basins, Alaska
Bruce Parks
1983, Water-Resources Investigations Report 83-4173
Water quality and streamflow in the Russian River basin during low-flow seasons (May to October), were studied for water years 1973-78 to document water-quality and streamflow conditions in the basin, and to determine the extent and cause of any water-quality impairment. The most important factors affecting surface-water quality and streamflow...
Backwater and discharge at highway crossings with multiple bridges in Louisiana and Mississippi
B.E. Colson, V.R. Schneider
1983, Water-Resources Investigations Report 83-4065
Data were collected for nine floods in Mississippi and Louisiana at eight stream crossings having two to six separate bridge openings. Discharge through each bridge, water surface profiles, valley cross sections, and bridge geometry were measured. The multiple openings were divided into equivalent single-opening cases by apportioning interior embankments in...
Use of digital land-cover data from the Landsat satellite in estimating streamflow characteristics in the Cumberland Plateau of Tennessee
E. F. Hollyday, G.R. Hansen
1983, Water-Resources Investigations Report 82-4059
Streamflow may be estimated with regression equations that relate streamflow characteristics to characteristics of the drainage basin. A statistical experiment was performed to compare the accuracy of equations using basin characteristics derived from maps and climatological records (control group equations) with the accuracy of equations using basin characteristics derived from...

Characteristics of Columbia River sediment following the eruption of Mount St. Helens on May 18, 1980
David Wellington Hubbell, Julija M. Laenen, Stuart W. McKenzie
1983, Circular 850-J
During several periods of volcanic-ash eruption at Mount St. Helens, Wash., (March 30, May 25-26, May 30-June 2, and June 12-13, 1980) strong winds from the north occurred at high altitudes. As a result, the volcanic ash fell some 50 miles to the south in the Bull Run watershed, the...
Water quality of Somerville Lake, south-central Texas
Emma McPherson, H.B. Mendieta
1983, Water-Resources Investigations Report 82-4124
Somerville Lake in south-central Texas is a shallow lake, with a mean depth of 14 feet. The maximum depth of the submerged channel of Yegua Creek is usually less than 35 feet and in most areas of the lake the depth is less than 10 feet. Several factors including thermal circulation...
Streamflow losses and changes in ground-water levels along the Salt and Gila Rivers near Phoenix, Arizona — February 1978 to June 1980
L. J. Mann, P. B. Rohne
1983, Water-Resources Investigations Report 83-4043
From March 1978 to June 1980, high runoff from the Salt and Verde drainage basins combined with large carryover storage in a reservoir system led to the release of about 8.26 million acre-feet of water. About 2.89 million acre-feet of the water was diverted above Granite Reef Dam, and about...
Three-dimensional digital-computer model of the principal ground-water reservoir of the Sevier Desert, Utah
W. F. Holmes
1983, Water-Resources Investigations Report 83-4179
The principal ground-water reservoir in part of the Sevier Desert, Utah was modeled using a three-dimensional finite-difference model. The model was calibrated by comparing computed and observed water-level measurements in 1952, simulating results of aquifer tests, and simulating ground-water withdrawals during 1952-81 and comparing computed water-level changes during 1952-82 to...

Statistical analysis and evaluation of water-quality data for selected streams in the coal area of east-central Montana
J. H. Lambing
1983, Water-Resources Investigations Report 83-4224
To document and evaluate existing conditions of water quality prior to proposed coal development in east-central Montana, water-quality data were collected at 23 sites on selected streams from October 1975 through September 1981. The data were statistically summarized and regression equations were developed to define relationships between water-quality variables. Where...
Evaluation of the San Dieguito, San Elijo, and San Pasqual hydrologic subareas for reclaimed water use, San Diego County, California
J. A. Izbicki
1983, Water-Resources Investigations Report 83-4044
A study was made to determine the suitability of three small hydrologic subareas in San Diego County, California, for reuse of municipal wastewater. Ground-water quality has been impacted by agricultural water use, imported water use, changes in natural recharge patterns, seawater intrusion, and intrusion of ground water from surrounding marine...
Recommended procedures and methodology of coal description
