Theoretical drawdown due to simulated pumpage from the Ohio River alluvial aquifer near Siloam, Kentucky
J. M. Kernodle
1977, Water-Resources Investigations Report 77-24
Theoretical drawdown due to simulated pumpage was determined for a site near Siloam, Kentucky by using a digital ground-water-flow model. The maximum sustained yield of water from the single well was shown to be less than 900 gallons per minute, and, for a simulated pumping rate of 450 gallons per...

Nature and extent of ground-water-quality changes resulting from solid-waste disposal, Marion County, Indiana
R. A. Pettijohn
1977, Water-Resources Investigations Report 77-40
Studies of seven landfills in the Indianapolis, Indiana, area indicate that in five of the landfills movement of ground water is from the deep aquifers into the uppermost aquifer. In the other two landfills, movement of ground water is from the shallow aquifers to the deeper aquifers, so that leachate...

This open-file report lists all Geological Survey, U.S. Bureau of Mines, and State of Alaska Division of Geological and Geophysical Surveys reports and maps on the geology, geophysics, and mineral and water resources of Alaska published or released to open files in 1976. They are listed by the quadrangles (scale...
Calculation of gravity and magnetic anomalies along profiles with end corrections and inverse solutions for density and magnetization
John W. Cady
1977, Open-File Report 77-463
An equation derived for the vertical gravity field due to a body with polygonal cross section and finite strike length. The equations consists of the 2-dimensional equation of Talwani, Worzel, and Landisman (1959), with the addition of end corrections. Equations for the magnetic field due to a similar body were...

Flood-hazard study: 100-year flood stage for Lucerne Lake, San Bernadino County, California
Mark William Busby
1977, Open-File Report 77-597
A study of the flood hydrology of Lucerne Valley, Calif., was made to develop the 100-year stage for Lucerne Lake. Synthetic-hydrologic techniques were used; and the 100-year flood stage was estimated to be at an elevation of 2,849.3 feet above mean sea level. Channel dimensions were measured at 59 sites...

Techniques for estimating flood discharges for Oklahoma streams; Techniques for calculating magnitude and frequency of floods in Oklahoma from rural and urban areas under 2500 square miles, with compilations of flood data through 1975
Wilbert O. Thomas Jr., Robert K. Corley
1977, Water-Resources Investigations Report 77-54
Statewide regression equations are defined for estimating peak discharges of floods having recurrence intervals ranging from 2 to 500 years. Contributing drainage area, main-channel slope and mean annual precipitation are the independent variables required for estimating flood discharges for rural streams. For urban streams the percentage of the basin that...

1977, Water-Resources Investigations Report 77-30
A flow model using finite-element techniques has been constructed for an alluvial aquifer in the Ocotillo-Coyote Wells Basin, Imperial County, Calif. Natural recharge is about 2,600 acre-feet per year, and estimated ground water in storage is 640 ,000 acre-feet. Pumpage totaled 880 acre-feet in 1975. The computed decline from steady-state...
Experimental study of artificial recharge alternatives in northwest Hillsborough County, Florida
William C. Sinclair
1977, Water-Resources Investigations Report 77-13
Extensive water withdrawal from the Floridan aquifer in the urban Tampa Bay area has induced leakage from the overlying surficial aquifer adversely effecting the water table and lake levels. Artificial recharge could reduce the impact of these effects. Four experiments were conducted to investigate possible recharge alternatives; sinkhole recharge, water-spreading,...
