Steady-state simulation of ground-water flow in the Rush Springs Aquifer, western Oklahoma
M.F. Becker
1998, Water-Resources Investigations Report 98-4082
A simplified steady-state ground-water flow model was prepared for the Rush Springs aquifer in western Oklahoma. A 3-kilometer square grid was established over the area containing two layers with 674 active nodes simulated in the model. The steady-state model simulation used a mean recharge rate of 3.05 x 10-4 feet...
Surface-water and suspended-sediment inflow and outflow for Nutria Reservoir No. 3, Zuni Indian Reservation, New Mexico, March 1994 to September 1995
A. C. Gellis
1998, Water-Resources Investigations Report 98-4083
Surface-water and suspended-sediment inflow to and outflow from Nutria Reservoir No. 3 on the Zuni Indian Reservation, western New Mexico, were calculated. The period of study was March 3, 1994, to September 30, 1995. Total runoff into Nutria Reservoir No. 3 during the study period was 6,812 acre-feet....
Surface-water-quality assessment of the upper Illinois River Basin in Illinois, Indiana, and Wisconsin — Spatial distribution of geochemicals in the fine fraction of streambed sediment, 1987
Faith A. Fitzpatrick, Terri Arnold, John A. Colman
1998, Water-Resources Investigations Report 98-4109
Geochemical data for the upper Illinois River Basin are presented for concentrations of 39 elements in streambed sediment collected by the U.S. Geological Survey in the fall of 1987. These data were collected as part of the pilot phase of the National Water-Quality Assessment Program. A total of 372 sites...
Stream habitat characteristics at selected sites in the Georgia-Florida coastal plain
L.J. Lewis, Michael Turtora
1998, Water-Resources Investigations Report 98-4013
Habitat characterization is part of a multidisciplinary approach to water-quality assessment implemented by the National Water-Quality Assessment Program. Habitat data were collected in the Georgia-Florida Coastal Plain study unit at 24 sites during 1993-95. Data were collected for habitat characteristics at three spatial scales: basin, segment, and reach. Basin data...
Streambed stability and scour potential at selected bridge sites in Michigan
D. J. Holtschlag, R. L. Miller
1998, Water-Resources Investigations Report 98-4024
Contraction scour in the main stream channel at a bridge and local scour near piers and abutments can result in bridge failure. Estimates of contraction-scour and local-scour potentials associated with the 100-year flood were computed for 13 bridge sites in Michigan by use of semi-theoretical equations and procedures recommended by...
Peak-flow frequency for tributaries of the Colorado River downstream of Austin, Texas
William H. Asquith
1998, Water-Resources Investigations Report 98-4015
A procedure to estimate the peak discharge associated with large floods is needed for tributaries of the Colorado River downstream of Austin, Texas, so that appropriate peak discharges can be used to estimate floodplain boundaries and used for the design of bridges and other structures. The U.S. Geological Survey, in...
Hydrogeology and simulation of ground-water flow in the Paluxy aquifer in the vicinity of Landfills 1 and 3, U.S. Air Force Plant 4, Fort Worth, Texas
Eve L. Kuniansky, Stanley T. Hamrick
1998, Water-Resources Investigations Report 98-4023
Ground-water contamination of the surficial terrace alluvial aquifer has occurred at U.S. Air Force Plant 4, a government-owned, contractor-operated facility, northwest of Fort Worth, Texas. A poorly constructed monitoring well, P–22M, open to the underlying middle zone of the Paluxy aquifer was installed at landfill 3, October 1987, allowing leakage...
Ground-water age, flow, and quality near a landfill, and changes in ground-water conditions from 1976 to 1996 in the Swinomish Indian Reservation, northwestern Washington
B. E. Thomas, S.E. Cox
1998, Water-Resources Investigations Report 98-4014
This report describes the results of two related studies: a study of ground-water age, flow, and quality near a landfill in the south-central part of the Swinomish Indian Reservation; and a study of changes in ground-water conditions for the entire reservation from 1976 to 1996. The Swinomish Indian Reservation is...
Regional rainfall-runoff relations for simulation of streamflow for watersheds in Du Page County, Illinois
James J. Duncker, Charles S. Melching
1998, Water-Resources Investigations Report 98-4035
Rainfall and streamflow data collected from July 1986 through September 1993 were utilized to calibrate and verify a continuous-simulation rainfall-runoff model for three watersheds (11.8--18.0 square miles in area) in Du Page County. Classification of land cover into three categories of pervious (grassland, forest/wetland, and agricultural land) and one category...
Fish communities and their relation to physical and chemical characteristics of streams from selected environmental settings in the Lower Susquehanna River basin, 1993-95
Michael D. Bilger, Robin A. Brightbill
1998, Water-Resources Investigations Report 98-4004
Studies of fish-community composition were conducted annually in selected reaches (from 100 to 303 meters in length) on seven streams from June 1993 to June 1995 within the Lower Susquehanna River Basin. In 1994, additional reaches were selected on three of the streams, resulting in a total of 28 samples....
