Comparison of the radioactive and modified techniques for measurement of stream reaeration coefficients
R. E. Rathbun, R. Stephen Grant
1978, Water-Resources Investigations Report 78-68
The radioactive and modified tracer techniques were used to measure the reaeration coefficients of two reaches each of Black Earth Creek and the Madison Effluent Channel near Madison, Wis. Comparison of the results showed that coefficients measured with the modified technique ranged from -8.96 to +3.61 and from +15.7 to...
Uranium and phosphate resources in the Cooper Formation of the Charleston region, South Carolina
Eric R. Force, G. S. Gohn, L.M. Force, B.B. Higgins
1978, Open-File Report 78-586
Phosphate deposits formerly exploited in the Charleston district were formed by weathering and reworking of the Cooper Formation (Eocene and Oliogcene). Previous workers have shown that unusual concentrations of uranium occur in phosphate-rich nodular material formed during subareal weathering. We found that the old mining district is on an erosional...
Strong-motion earthquake accelerograms digitization and analysis
A. Gerald Brady, Virgilio Perez
1978, Open-File Report 78-941
This is the third of a series of reports planned to include the results of digitization and routine analyses of strong-motion earthquake accelerograms published by the U.S. Geological Survey. Serving as a model for this effort is the collection of data reports published by the Earthquake Engineering Research Laboratory of...
Estimation of ground motion parameters
David M. Boore, W. B. Joyner, A.A. Oliver, R.A. Page
1978, Circular 795
Strong motion data from western North America for earthquakes of magnitude greater than 5 are examined to provide the basis for estimating peak acceleration, velocity, displacement, and duration as a function of distance for three magnitude classes. A subset of the data (from the San Fernando earthquake) is used to...
Floods in the Skunk River basin, Iowa
Albert J. Heinitz, Sulo Werner Wiitala
1978, Open-File Report 79-272
Evaluation of flood hazards, and the planning, design, and operation of various facilities on flood plains require information on floods. This report provides information on flood stages and discharges, flood magnitudes and frequency, and flood profiles for the Skunk River and some of its tributaries. It covers the Skunk --...
Analysis of urban storm-water quality for seven basins near Portland, Oregon
Timothy L. Miller, Stuart W. McKenzie
1978, Open-File Report 78-662
Over a 1.5-year period, water-quality data were collected for seven small drainage basins in urban aeas of Portland, Oreg. Analysis of the data followed three approaches. First, the constituent concentrations were analyzed. Average concentrations of suspended sediment, settleable solids, and fecal coliform bacteria generally exceeded levels expected for secondary waste-treatment...
A preliminary appraisal of the impact of agriculture on ground-water availability in southwest Georgia
L.D. Pollard, R.G. Grantham, H.E. Blanchard Jr.
1978, Water-Resources Investigations Report 79-7
Irrigated acreage in the study area in southwest Georgia increased from 130,000 acres in 1976 to 261,000 in 1977. Acreage irrigated entirely by ground water increased 85 percent for the same period. The largest quantity of ground water used for irrigation was in the Dougherty Plain district, where 92 percent...
Maps showing formation temperatures and configurations of the tops of the Minnelusa Formation and the Madison Limestone, Powder River basin, Wyoming, Montana, and adjacent areas
William J. Head, Kevin Thomas Kilty, Richard K. Knottek
1978, Open-File Report 78-905
This report is part of a study to describe the hydrogeologic framework needed to evaluate the water resources of the Paleozoic age aquifers in the Northern Great Plains coal region. Preliminary studies by the U.S. Geological Survey and State agencies in Wyoming, Montana, and South Dakota have indicated that these...
Allocation of subsamples of Apollo 17 lunar rocks from the boulder at station 7, for study by the International Consortium
Jean A. Minkin, Carolyn L. Thompson, E. C. T. Chao
1978, Open-File Report 78-511
The International Consortium was organized, under the leadership of E. C. T. Chao, to conduct a systematic interdisciplinary study of four lunar rock samples (77135, 77115, 77075 and 77215) collected by the Apollo 17 astronauts as representative of the four lithologies they recognized in the boulder at station 7. Tables...
A computer program designed to produce tables from alphanumeric data
Jennie L. Ridgley, Robert Wayne Schnabel
1978, Open-File Report 78-875
This program is designed to produce tables from alphanumeric data. Each line of data that appears in the table is entered into a data file as a single line of data. Where necessary, a predetermined delimiter is added to break up the data into column data. The program can process...
Hydrologic analysis of the U.S. Bureau of Mines' underground oil-shale research-facility site, Piceance Creek Basin, Rio Blanco County, Colorado
R. H. Dale, John B. Weeks
1978, Water-Resources Investigations Report 78-28
The U.S. Bureau of Mines plans to develop an underground oil-shale research facility near the center of Piceance Creek basin in Colorado. The oil-shale zone, which is to be penetrated by a shaft, is overlain by 1,400 feet of sedimentary rocks, primarily sandstone and marlstone, consisting of two aquifers separated...
