Field studies of borehole gamma-ray spectrometer methods for mineral exploration; a selected bibliography
Frank E. Senftle
1980, Open-File Report 80-503
A finite-difference digital model was developed to simulate the effects of a proposed well field on the water levels in existing wells in the Salt River Indian Reservation, which is in the southeastern part of Paradise Valley in central Arizona. The model area includes about 600 square miles in Paradise...

1980, Open-File Report 80-624
The U. S. Geological Survey (USGS) is making available four multichannel profiles collected by Teledyne Exploration in 1977 by means of a 48-channel streamer (3600 m long) and four airguns (2160 in). Profiles 15 and 16 were processed by.Teledyne Exploration and profiles 14 and 17 were processed on the Phoenix...
Scintillation detectors in gamma spectral logging; geometry, absorption and calibration
Ulrich Schimschal
1980, Open-File Report 80-688
The theory for the evaluation of the effects of geometry in gamma ray absorption is developed for cylindrical scintillation detectors as applicable to borehole gamma spectrometry. The results of a laboratory experiment are shown for comparison. A calibration procedure to determine detector efficiency is given for application to borehole probes....

Techniques for estimating flood peaks, volumes and hydrographs on small streams in South Dakota
Lawrence D. Becker
1980, Water-Resources Investigations Report 80-80
Procedures are defined for estimating the magnitude and frequency of future flood peaks and flood volumes and for estimating the expected hydrograph shape of rainfall-induced runoff of small streams in South Dakota. The procedures are applicable to flood flows that are not significantly affected by artificial storage or other manmade...

Nitrogen in ground water and surface water from sewered and unsewered areas, Nassau County, Long Island, New York
Stephen E. Ragone, B. G. Katz, G.E. Kimmel, J.B. Lindner
1980, Water-Resources Investigations Report 80-21
Data on nitrogen in groundwater and surface waters in the sewered and unsewered parts of Nassau County were analyzed to evaluate the principal sources of nitrogen and to determine what factors significantly affect its concentration in the upper glacial aquifer and the underlying Magothy aquifer. Nitrate data for water samples...

1980, Professional Paper 1107
The 3,550 square miles of the Upper Chattahoochee River basin is an area of diverse physiographic and land-use characteristics. The headwater areas are mountainous with steep, relatively narrow channels. Land in the headwater areas is heavily forested, but small towns and farms are common in the valleys of large streams....
Composition and properties of the Pierre Shale and equivalent rocks, northern Great Plains region
Leonard Gene Schultz, H. A. Tourtelot, J. R. Gill, J.G. Boerngen
1980, Professional Paper 1064-B
The Pierre Shale and equivalent rocks of Late Cretaceous age consist in the east-central Dakotas of several hundred feet of offshore-marine shale and minor marl; in west-central Montana near the sediment source the equivalents of the Pierre Shale consist of several thousand feet of volcanic-rich and mostly nonmarine sediments; and...
Cape Cod Aquifer, Cape Cod, Massachusetts
Barbara J. Ryan
1980, Open-File Report 80-571
Ground water was the major source of drinking water on Cape Cod, Massachusetts in 1978. Withdrawals from over 100 municipal wells averaged 17.5 million gallons per day in 1978. Private wells on Cape Cod are estimated to number 15,000. Ground water occurs primarily under unconfined or water-table conditions. Artesian conditions...

Water-quality data collected in the upper Oyster Creek drainage basin, Ocean County, N.J., indicate that the stream has excellent water quality except for a persistently low pH. The mean concentrations of the major inorganic ions were all less than 6.0 milligrams per liter. Mean concentrations of total nitrogen and total...

Effects of the proposed Prosperity Reservoir on ground water and water quality in lower Center Creek basin, Missouri
Wayne R. Berkas, James H. Barks
1980, Water-Resources Investigations Report 80-88
Effects of the proposed Prosperity Reservoir on ground water and water quality in lower Center Creek basin depend partly on the effectiveness of Grove Creek as a hydrologic boundary between the reservoir site and the Oronogo-Duenweg mining belt. Results of two dye traces indicate that Grove Creek probably is not...
