Simulated drawdown for selected well fields in the Ohio River alluvial aquifer
Hayes F. Grubb
1975, Water-Resources Investigations Report 74-2
Drawdown due to pumping was simulated for three sites in the alluvial aquifer adjacent to the Ohio River by digital modeling techniques. Two well-field arrangements were used at each site. The initial well-field arrangement at each site consisted of three wells located in a line parallel to the Ohio River....

Rapid analysis of silicate, carbonate, and phosphate rocks: Revised edition
Leonard Shapiro
1975, Bulletin 1401
The rapid methods previously used by the U.S. Geological Survey to determine the major constituents of rocks have been modified to introduce atomic absorption spectrometry (AAS) where applicable. Two procedures are available for determining 10 constituents: one, from a single solution prepared by a nitric-acid dissolution of a lithium metaborate-lithium...

Sediment transport, turbidity, channel configuration, and possible effects of impoundment of the Mad River, Humboldt County, California
William M. Brown III
1975, Water-Resources Investigations Report 75-26
Sediment-transport conditions were determined at two stations, Mad River near Arcata and Mad River near Kneeland. Using a release-flow model and an empirical equation, the suspended-sediment discharge at Kneeland was estimated to be about 60 percent of the suspended-sediment discharge at the Arcata station. The study of the proposed impoundment...

Jerry L. Hughes
1975, Water-Resources Investigations Report 75-7
The discharge of 3 acre-feet (4 x 10-3 cubic hectometres) per year of Class-I wastes in the Haystack Butte area of Edwards Air Force Base, Calif., has been proposed by the Air Force. Evaporation in this arid basin exceeds the 4 inches (100 millimetres) of annual precipitation. Fifteen test holes,...
Digital model simulation of the glacial-outwash aquifer at Dayton, Ohio
Richard E. Fidler
1975, Water-Resources Investigations Report 75-18
Dayton, Ohio and its environs obtain most of their water from wells which penetrate highly productive glacial-outwash deposits underlying the Great Miami River and its tributaries and receive recharge by induced streambed leakage. Combined municipal and industrial use of ground water in the 90-square-mile area has increased from about 180...
Digital models of a glacial outwash aquifer in the Pearl-Sallie Lakes area, west-central Minnesota
S. P. Larson, Mark S. McBride, R. J. Wolf
1975, Water-Resources Investigations Report 75-40
-p^e need for study of lake-ground-water interchange has been accentuated by eutrophication of lakes in the Pearl-Sallie Lakes area of west-central Minnesota. The local ground-water flow system is dominated by an outwash aquifer that is sandwiched between two till layers in the western part of the area and exposed at...
Simulation of dissolved oxygen and biochemical oxygen demand, Plantation Canal, Broward County, Florida with an evaluation of the QUAL-I model for use in south Florida
Thomas N. Russo, Raul S. McQuivey
1975, Water-Resources Investigations Report 75-59
A mathematical model; QUAL-I, developed by the Texas Water Development Board, was evaluated as a management tool in predicting the spatial and temporal distribution of dissolved oxygen and biochemical oxygen demand in Plantation Canal. Predictions based on the QUAL-I model, which was verified only against midday summer-flow conditions, showed that...

Flood-prone areas of Gadsden County, Florida
Roger P. Rumenik, C.A. Pascale, D.F. Tucker
1975, Water-Resources Investigations Report 75-31
Gadsden County is an area of 508 square miles in northwest Florida. The topography of the county is diverse and ranges in altitude from about 50 to 300 feet above mean sea level. Well drained steep hillsides and narrow ridgetops give way to broad, nearly level, poorly drained plateaus which...

United States Geological Survey's hydrogeological research programs and plans related to disposal of radioactive waste into geologic formations
George D. DeBuchananne, William Stephens Twenhofel
1975, Open-File Report 75-626
The Geological Survey, United States Department of Interior, has cooperated with the United States Energy Research and Development Administration, formerly the Atomic Energy Commission, for more than 30 years on research related to the disposal of radioactive waste into geological formations. Results of most of this research effort have been...
Notes on some experiments on the application of subtractive compensation to USGS seismic magnetic tape recording and playback systems
Jerry P. Eaton
1975, Open-File Report 75-663
The purpose of these experiments is to lay the groundwork for the implementation of subtractive compensation of the USGS seismic network tape playbacks utilizing the Develco model 6203 discriminators at a x1 playback speed. Although the Develco discriminators were designed for this application and a matching Develco compensation discriminator was...

Water availability, Jefferson County, Alabama
Alfred L. Knight
1975, Open-File Report 75-461
The average annual precipitation in Jefferson County is about 53 inches (1,346.2 millimeters) or about 2,820 mgd (million gallons per day), which is equivalent to 124 m3/s (cubic meters per second). Part of the rainfall (about 1,130 mgd or 50 m3/s) runs off directly into streams, and the remaining 1,690...

Formulation and use of practical models for river-quality assessment
Walter G. Hines, D. A. Rickert, S. W. McKenzie, J. P. Bennett
1975, Circular 715-B
For nearly half a century the Willamette River in Oregon experienced severe dissolved-oxygen problems related to large loads of organically rich waste waters from industries and municipalities. Since the mid-1950 's dissolved oxygen quality has gradually improved owing to low-flow augmentation, the achievement of basinwide secondary treatment, and the use...
