Interim data report on the geohydrology of the proposed waste isolation pilot plant site, southeast New Mexico
Jerry W. Mercer, R.B. Orr
1979, Water-Resources Investigations Report 79-98
Data collected at the proposed Waste Isolation Pilot Plant site in southeast New Mexico through September 1977 help define hydrologic conditions at the contact between the Permian Rustler and Salado Formations, and Culebra and Magenta Dolomite Members of the Rustler Formation. Preliminary calculations of transmissivity along the Rustler-Salado contact range...
Digital model of the Hollister Valley ground-water basin, San Benito County, California
G.W. Kapple
1979, Water-Resources Investigations Report 79-32
A two-dimensional finite-difference digital model was constructed to simulate effects of proposed pumping and recharge schemes on water levels in the Hollister Valley ground-water basin. Pumping rates in the valley are expected to increase from 24,000 acre-feet per year in 1968 to an ultimate rate of 38,500 acre-feet per year....
Simulated changes in ground-water levels and streamflow resulting from future development (1970 to 2020) in the Platte River basin, Nebraska
E.G. Lappala, P. A. Emery, F.J. Otradovsky
1979, Water-Resources Investigations Report 79-26
Future changes in ground-water levels and streamflow caused by a limited set of water-resources development conditions were simulated with digital models of stream-aquifer systems within the Platte River Basin, Nebraska. Simulated water-resources use in the basin included private development of ground water for irrigation, Federal development of surface-water systems for...
Distribution of nitrate and related nitrogen species in the unsaturated zone, Redlands and vicinity, San Bernardino County, California
John M. Klein, Wesley L. Bradford
1979, Water-Resources Investigations Report 79-60
Nitrogen in the unsaturated soil zone in the vicinity of Redlands in San Bernardino County, Calif., has been suspected as the source of nitrate in water from wells. Plans have been made to recharge the aquifer with imported surface water. If this occurs, the rising water table will intercept soluble...
Saline-seep development in the Hailstone Basin, northern Stillwater County, Montana
Barney D. Lewis, Stephen G. Custer, Marvin R. Miller
1979, Water-Resources Investigations Report 79-107
As a result of an increase in saline seep occurrence in Montana, a study was begun in 1974 to determine the hydrogeology of saline seeps in the Hailstone basin. The aquifer is composed of colluvium of Holocene age. The impermeable Cretaceous Niobrara Formation underlies the saturated zone basinwide. The ground-water...
Flood characteristics of Alaskan streams
R. D. Lamke
1979, Water-Resources Investigations Report 78-129
Peak discharge data for Alaskan streams are summarized and analyzed. Multiple-regression equations relating peak discharge magnitude and frequency to climatic and physical characteristics of 260 gaged basins were determined in order to estimate average recurrence interval of floods at ungaged sites. These equations are for 1.25-, 2-, 5-, 10-, 25-,...
Estimation of floods of various frequencies for the small ephemeral streams in eastern Washington
W.L. Haushild
1979, Water-Resources Investigations Report 79-81
Equations were developed to estimate the magnitude of floods for various occurrence frequencies at ungaged sites on ephemeral streams that drain small, relatively undeveloped basins in the semiarid part of eastern Washington. The equations were developed from regression analyses that used the logarithms of the longitude indexes of gaged sites,...
Ground water in the vicinity of Capulin, New Mexico
D.L. Hart Jr., Christian Smith
1979, Water-Resources Investigations Report 79-79
The alluvial deposits within a closed basin near Capulin, New Mexico, are estimated to have 189,000 acre-feet of water in storage. These deposits have an estimated average transmissivity of 400 feet squared per day and represent the major source of ground water. Well yields range from a few gallons per...
Experimental salinity alleviation at Malaga Bend of the Pecos River, Eddy County, New Mexico
John S. Havens, D. W. Wilkins
1979, Water-Resources Investigations Report 80-4
Upward-leaking brine, from a confined aquifer at the base of the Rustler Formation, mixes with fresher water in a shallow aquifer, resulting in discharge to the Pecos River in southern Eddy County, New Mexico, of about 0.5 cubic feet per second of saturated brine. Pumping brine from the aquifer at...
