Climatic data for Williams Lake, Hubbard County, Minnesota, 1982
D.O. Rosenberry, A.M. Sturrock, J.L. Scarborough, T. C. Winter
1988, Open-File Report 88-89
Research on the hydrology of Williams Lake, north-central Minnesota includes study of evaporation. Those climatic data needed for energy budget and mass transfer studies are presented , including: water surface temperature, dry-bulb and wet-bulb air temperatures, wind speed, precipitation, and solar and atmospheric radiation. Some calculated values necessary for these...
Relation of salinity and selenium in shallow ground water to hydrologic and geochemical processes, western San Joaquin Valley, California
S. J. Deverel, S.K. Gallanthine
1988, Open-File Report 88-336
Salinity and selenium concentrations in shallow ground water of the western San Joaquin Valley, California, are related to the geomorphology and hydrology of the alluvial fans. The highest salinity and selenium concentrations in shallow ground water occur in alluvium deposited by ephemeral streams and at the margins of the major...
Water resources of Oley Township, Berks County, Pennsylvania
G. N. Paulachok, C. R. Wood
1988, Water-Resources Investigations Report 87-4065
Oley Township covers an area of 24 square miles, about half of which is underlain by highly permeable carbonate rocks. Nondomestic wells in these rocks typically have yields of 200 gallons per minute, and some wells yield more than 1,000 gallons per minute. Ground-water yield for Oley Township is about...
Annual yield and selected hydrologic data for the Arkansas River Basin compact, Arkansas-Oklahoma, 1987 water year
M. A. Moore, T.E. Lamb, L.D. Hauth
1988, Open-File Report 88-301
The computed annual yield and deficiency of the subbasins are defined in the Arkansas River Compact, Arkansas-Oklahoma, are given in tables. Actual runoff from the subbasins and depletion caused by major reservoirs in the compact area are also given in tabular form. Monthly, maximum, and mean discharges are shown for...
Water-resources activities of the U.S. Geological Survey in New Mexico; fiscal year 1988
R. L. Knutilla (compiler)
1988, Open-File Report 88-473
All hydrologic investigations in the New Mexico District in progress during fiscal year 1988 are summarized. The summaries include sections on the problem addressed, the objective and approach of the investigation, progress of the investigation. Reports released during 1986 and 1987 are listed. The New Mexico District office organization, cooperating...
A finite-element model for simulating hydraulic interchange of surface and ground water
K. C. Glover
1988, Water-Resources Investigations Report 86-4319
A model was developed to be useful for predicting changes in streamflow as a result of groundwater pumping. The stream aquifer model is especially useful for simulating streams that flow intermittently owing to leakage to the aquifer or diversion for irrigation or streams that become perched owing to declining hydraulic...
Ground-water flow and solute transport at a municipal landfill site on Long Island, New York — Part 2: Simulation of ground-water flow
E. J. Wexler, P. E. Maus
1988, Water-Resources Investigations Report 86-4106
Data on the hydrogeology of a 26-sq-mi area surrounding the Brookhaven landfill site in central Suffolk County were collected as part of a hydrologic investigation of solute transport from the site. These data were used to develop a steady-state groundwater flow model of the upper glacial (water table) aquifer in...
Results of qualification tests on water-level sensing instruments, 1986
Randolph R. Holland, Donald H. Rapp
1988, Open-File Report 88-193
This report presents to users of hydrological instrumentation and U.S. Geological Survey procurement personnel a list of instruments that have met or exceeded the Survey 's minimum performance requirements for water level sensing instruments. The Hydrologic Instrumentation Facility at the National Space Technology Laboratories, Mississippi conducted qualification tests on four...
A strategy for collecting ground-water data and developing a ground-water model of the Missouri River alluvial aquifer, Woodbury and Monona Counties, Iowa
Robert C. Buchmiller
1988, Open-File Report 87-452
A ground-water-flow model and plan for obtaining supporting data are proposed for a part of the Missouri River alluvial aquifer in Woodbury and Monona Counties, Iowa. The proposed model and the use of the principle of superposition will aid in the interpretation of the relation between ground water and surface...
Hydrology of Alkali Creek and Castle Valley Ridge coal-lease tracts, central Utah, and potential effects of coal mining
R. L. Seiler, R. L. Baskin
1988, Water-Resources Investigations Report 87-4186
The Alkali Creek coal-lease tract includes about 2,150 acres in the Book Cliffs coal field in central Utah, and the Castle Valley Ridge coal-lease tract includes about 3,360 acres in the Wasatch Plateau coal field, also in central Utah. Both the Alkali Creek and Castle Valley Ridge coal-lease tracts are...
Hydrology and water quality of Delavan Lake in southeastern Wisconsin
S. J. Field, M.D. Duerk
1988, Water-Resources Investigations Report 87-4168
Delavan Lake is a eutrophic, recreational lake in a densely populated area of southeastern Wisconsin. Sewage effluent and septic tank drainage were diverted out of the drainage basin of the lake to improve its water quality in 1981. The worst known blue-green algal bloom occurred in the lake in the...
Borehole geophysics applied to ground-water investigations
W.S. Keys
1988, Open-File Report 87-539
The purpose of this manual is to provide hydrologists, geologists, and others who have the necessary training with the basic information needed to apply the most useful borehole-geophysical-logging techniques to the solution of problems in ground-water hydrology. Geophysical logs can provide information on the construction of wells and on the...
A modular three-dimensional finite-difference fround-water flow model
Michael G. McDonald, Arlen W. Harbaugh, Weixing Guo (translator), Guoping Lu
1988, Techniques of Water-Resources Investigations 06-A1
This report presents a finite-difference model and its associated modular computer program. The model simulates flow in three dimensions. The report includes detailed explanations of physical and mathematical concepts on which the model is based and an explanation of how those concepts are incorporated in the modular structure of the...
Selenium accumulation in benthic bivalves and fine sediments of San Francisco Bay, the Sacramento-San Joaquin Delta, and selected tributaries
Carolyn Johns, Samuel N. Luoma, Virginia Elrod
1988, Estuarine, Coastal and Shelf Science (27) 381-396
Spatial distributions of selenium were determined in fine-grained, oxidized, surface sediments and in two benthic bivalves (Corbicula sp., a suspension-feeding freshwater clam, and Macoma balthica, a deposit-feeding brackish-water clam) within San Francisco Bay, the San Joaquin River and three river systems unlikely to be subject to selenium inputs. Biologically available selenium enters...
