Altitude and configuration of the water table in the High Plains Aquifer in Kansas, 1965
Marilyn E. Pabst, Lloyd E. Stullken
1982, Open-File Report 82-449
The High Plains aquifer in Kansas is a part of a regional system that extends South Dakota to Texas. The aquifer in Kansas underlies an area of 31,000 square miles in the western and south-central part. This aquifer is a hydraulically connected assemblage of unconsolidated water-bearing deposits of Tertiary and...
Water quality of Lake Granbury, north-central Texas
Freeman L. Andrews, Jeffrey L. Strause
1982, Open-File Report 82-676
During water years 1970-79, the concentrations of the major dissolved constituents in Lake Granbury on the Brazos River in north-central Texas averaged about 1,800 milligrams per liter of dissolved solids, 700 milligrams per liter of chloride, and 350 milligrams per liter of sulfate. The water was generally very hard (hardness...
Water resources data for Washington, water year 1980: Vol. 2 - Eastern Washington
Water Resources Division, U.S. Geological Survey
1982, Water Data Report WA-80-2
Water Resources data for the 1980 water year for Washington consists of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels and water quality of ground-water wells. This report in two volumes contains records for water discharge at...
Water-quality assessment of the Merced River, California
Stephen K. Sorenson
1982, Open-File Report 82-450
The Merced River and its major tributaries have been subject of water-quality and water-quantity studies by local, State, and Federal agencies since before 1900. Data have been compiled and analyzed, and even though water-quality problems exist in the basin, the water generally is of good quality for most of the...
Quadratic spline subroutine package
Lowell A. Rasmussen
1982, Water-Resources Investigations Report 82-41
A continuous piecewise quadratic function with continuous first derivative is devised for approximating a single-valued, but unknown, function represented by a set of discrete points. The quadratic is proposed as a treatment intermediate between using the angular (but reliable, easily constructed and manipulated) piecewise linear function and using the smoother...
Whole-rock chemical composition of some samples from two drill hole cores in the Capps coal field, Beluga coal area, south-central Alaska
T. K. Hinkley, K. S. Smith, J. L. Peard, M.L. Tompkins
1982, Open-File Report 82-672
Whole-rock chemical analysis was done on samples from drill cores of rocks lying atop and between coal beds in the Beluga coal area, south-central Alaska. The samples were classified as sandstone, siltstone or claystone at time of hand specimen description. Chemical data were compared to those from corresponding rocks from...
A model for the simulation of flow of variable-density ground water in three dimensions under steady-state conditions
Emanuel Weiss
1982, Open-File Report 82-352
A computer program has been developed as part of the U.S. Geological Survey's national program of Regional Aquifer System Analysis (RASA) that generates input to ground-water flow models to enable them to simulate variable-density ground-water flow. Information required for the program's operation is: aquifer elevation, thickness, and ground-water density. Included...
