Calibration and use of an interactive-accounting model to simulate dissolved solids, streamflow, and water-supply operations in the Arkansas River basin, Colorado
A.W. Burns
1989, Water-Resources Investigations Report 88-4214
An interactive-accounting model was used to simulate dissolved solids, streamflow, and water supply operations in the Arkansas River basin, Colorado. Model calibration of specific conductance to streamflow relations at three sites enabled computation of dissolved-solids loads throughout the basin. To simulate streamflow only, all water supply operations were incorporated in...
Water resources data, Florida; Water year 1988; Volume 2A. South Florida surface water
W.J. Haire, E.C. Price, A. Lietz, E. Workman
1989, Water Data Report FL-88-2A
Water resources data for the 1988 water year in Florida consists of continuous or daily discharge for 338 streams, periodic discharge for 34 streams, miscellaneous discharge for 28 streams, continuous or daily stage for 152 streams, periodic stage for 29 streams, peak discharge for 71 streams, continuous daily tide stage...
Summary of fluvial-sediment studies in Ohio, through 1987
S. M. Hindall
1989, Water-Resources Investigations Report 89-4066
The U.S. Geological Survey, in cooperation with other Federal, State, and local agencies, has been collecting fluvial sediment data from Ohio streams since April 1950. This report summarizes the data collected for the period April 1950 through 1987. In addition, trends in annual suspended-sediment discharge in Ohio streams are examined...
Appraisal of ground-water quality in the Bunker Hill Basin of San Bernardino Valley, California
L. F. Duell Jr., R. A. Schroeder
1989, Water-Resources Investigations Report 88-4203
Water samples were collected from 47 wells and analyzed for concentration of major inorganic ions, nitrogen species, and volatile (purgeable) organic priority pollutants to assess groundwater quality in the Bunker Hill basin, California. Data were supplemented with additional analysis of nitrate, tetrachloroethylene, and trichloroethylene made by other agencies. The organic...
Hydrogeology of the southwestern part of the town of Hempstead, Nassau County, New York
Richard K. Krulikas
1989, Water-Resources Investigations Report 85-4288
The groundwater resources of the southwestern part of the Town of Hempstead in Nassau County, NY were investigated in 1984. The area studied encompasses 85 sq mi, or 68% of the town 's 125-sq mi area. The groundwater reservoir underlying the area consists of unconsolidated gravel, sand, silt, and clay...
Geohydrology and ground-water quality at selected sites in Meade County, Kentucky, 1987-88
D. S. Mull, A.G. Alexander, P.E. Schultz
1989, Water-Resources Investigations Report 89-4108
Meade County in north-central Kentucky is about 305 sq mi in size, and is underlain by thick beds of limestone and dolomite which are the principal sources of drinking water for about 8 ,500 residents. About half the area contains mature, karst terrain with abundant sinkholes, springs, and caves. Because...
Water resources of the upper Big Wood River basin, Idaho
S.A. Frenzel
1989, Water-Resources Investigations Report 89-4018
Mean annual water yields, estimated using a water-budget method, for the upper Big Wood River basin above Glendale Road and for Trail Creek, Warm Springs Creek, and East Fork Big Wood River, Idaho were 410,000, 50,000, 60,000 and 50,000 acre-ft, respectively. Yields also were estimated for 1986 and 1987 water...
Simulation of streamflow in small drainage basins in the southern Yampa River basin, Colorado
R. S. Parker, J. M. Norris
1989, Water-Resources Investigations Report 88-4071
Coal mining operations in northwestern Colorado commonly are located in areas that have minimal available water-resource information. Drainage-basin models can be a method for extending water-resource information to include periods for which there are no records or to transfer the information to areas that have no streamflow-gaging stations. To evaluate...
Preliminary analysis of the shallow ground-water system in the vicinity of the Grand Calumet River/Indiana Harbor Canal, northwestern Indiana
Lee R. Watson, R. J. Shedlock, K. J. Banaszak, L. D. Arihood, P. K. Doss
1989, Open-File Report 88-492
The shallow groundwater system in the vicinity of the Grand Calumet River-Indiana Harbor Canal, Indiana was analyzed from June 1985 to May 1986. This analysis was done to obtain detailed information about the physical characteristics of the Calumet aquifer and the shallow groundwater flow system. 36 shallow wells were installed...
Cyclic injection, storage, and withdrawal of heated water in a sandstone aquifer at St. Paul, Minnesota: Field observations, preliminary model analysis, and aquifer thermal efficiency
Robert T. Miller
1989, Open-File Report 89-261
In May 1980, the University of Minnesota began a project to evaluate the feasibility of storing heated (150 °C (degree Celsius)) water in the deep (180 to 240 m (meters)) Franconia-Ironton-Galesville aquifer and later recovering it for space heating. The Aquifer Thermal-Energy Storage (ATES) system was doublet-well design in which...
Aquifers in Cretaceous rocks of the central Coastal Plain of North Carolina
M. D. Winner Jr., W.L. Lyke
1989, Water-Resources Investigations Report 87-4178
Aquifers in rocks of Cretaceous age are the major source of groundwater for public supplies in the central Coastal Plain. These aquifers consist of sand, gravel, and limestone beds of the Peedee, Black Creek, and the upper and lower Cape Fear aquifers, each separated by a confining unit composed of...
Investigations of the characteristics, origin, and residence time of the upland residual mantle of the Piedmont of Fairfax County, Virginia
M.J. Pavich, G. W. Leo, S. F. Obermeier, J.R. Estabrook
1989, Professional Paper 1352
Undisturbed cores of upland regolith developed from a variety of crystalline rocks of the Piedmont province in Fairfax County, Va., have been obtained by using a combination of Shelby tubes, Denison sampler, and modified diamond core drilling. The core study correlated variations in chemistry, mineralogy, and texture with engineering properties...
