Heat-flow measurements at shot points along the 1978 Saudi Arabia seismic deep-refraction line; Part I, Results of the measurements
M. E. Gettings, Abdullah Showail
1982, Open-File Report 82-793
Heat-flow measurements were made at five onland shot points of the 1978 Saudi Arabian seismic deep-refraction line, which sample major tectonic elements of the Arabian Shield along a profile from Ar Riyad to the Farasan Islands. Because of the pattern drilling at each shot point, several holes (60 m deep)...
Near-station terrain corrections for gravity data by a surface-integral technique
M. E. Gettings
1982, Open-File Report 82-1045
A new method of computing gravity terrain corrections by use of a digitizer and digital computer can result in substantial savings in the time and manual labor required to perform such corrections by conventional manual ring-chart techniques. The method is typically applied to estimate terrain effects for topography near the...
Field data describing the movement and storage of sediment in the East Fork River, Wyoming; Part III, river hydraulics and sediment transport, 1980
W. W. Emmett, R. M. Myrick, R.H. Meade
1982, Open-File Report 82-359
Frequent measurements of river stage, water discharge, sediment-transport rate and particle-size gradation, and river slope were made at 44 cross sections along a 1.83-kilometer reach of East Fork River, Wyoming, during the spring 1980 snowmelt runoff. Data are tabulated and explanatory text facilitates its use for description of river hydraulics...
Annual Nutrient Loadings, Primary Productivity, and Trophic State of Lake Koocanusa, Montana and British Columbia, 1972-80
Paul F. Woods
1982, Professional Paper 1283
Limnological data collected at Lake Koocanusa were used to investigate the relationship of nutrient loadings, primary productivity, and trophic state of the reservoir during 1972-80. The reservoir, on the Kootenai River, was impounded by Libby Dam on March 21, 1972. Manipulation of the 7.16-cubic-kilometer reservoir for flood control, its primary...
Progress report on lithium-related geologic investigations in Bolivia
J.R. Davis, K. A. Howard, S.L. Rettig, R. L. Smith, G. E. Ericksen, Francois Risacher, Hugo Alarcon, Ricardo Morales
1982, Open-File Report 82-782
The September 1, 1981, Samoa Islands Region earthquake occurred at the extreme northern end of the Tonga arc in a region where the Pacific plate may be disjointed along a hinge fault. In the last 50 years, magnitude 7 or greater earthquakes have occurred in this region on the average...
Water-quality and hydrogeologic data for three phosphate industry waste-disposal sites in central Florida, 1979-80
Ronald L. Miller, Horace Sutcliffe Jr.
1982, Water-Resources Investigations Report 81-84
This report is a complilation of geologic, hydrologic, and water-quality data and information on test holes collected in the vicinity of gypsum stack complexes at two phosphate chemical plants and one phosphatic clayey waste disposal pond at a phosphate mine and beneficiation plant in central Florida. The data were collected...
Small-stream flood investigations in Minnesota, October 1958 to September 1980
Kurt T. Gunard, C.J. Smith
1982, Open-File Report 82-433
An investigation of flood flows from small drainage basins in Minnesota is being made to aid in the design of bridges, culverts and other highway drainage structures. Results of the investigation provide peak-flow data on streams generally with drainage areas less than 200 square miles, placing particular emphasis on those...
Water-quality assessment of the Merced River, California
Stephen K. Sorenson
1982, Open-File Report 82-450
The Merced River and its major tributaries have been subject of water-quality and water-quantity studies by local, State, and Federal agencies since before 1900. Data have been compiled and analyzed, and even though water-quality problems exist in the basin, the water generally is of good quality for most of the...
Water-quality assessment of the American River, California
M.V. Shulters
1982, Open-File Report 82-763
Based on an analysis of water-quality data from more than 168 sites, the American River was found to be of overall good quality and suitable for all beneficial uses specified by the State of California, even though its natural condition has been altered by man 's activities in the basin....
Hydrologic data collected in and around a surface coal mine, Clay and Vigo counties, Indiana, 1977-80
Linda L. Bobo, Stephen E. Eikenberry
1982, Open-File Report 82-639
Few data are available for evaluating water-quality and other hydrologic properties in and around surface coal mines, particularly in areas where material having a high potential for acid-production is selectively buried. This report contains hydrologic data collected in an active coal mining area in Clay and Vigo Counties, Indiana, from...
Availability of water from aquifers in upstate New York
Irwin H. Kantrowitz, Deborah S. Snavely
1982, Open-File Report 82-437
Two maps give the locations and estimated yields of unconsolidated and bedrock aquifers of upstate New York, excluding Long Island. The map of surficial deposits give estimates of well yield, aquifer yield, and specific capacity; the map of bedrock units gives the same information and also delineates areas in which...
Flood data in West Windsor Township, Mercer County, New Jersey, through 1981 water year
D.A. Harriman, A. J. Velnich
1982, Open-File Report 82-434
Flood stages and peak discharges are described for 13 sites on streams in West Windsor Township, Mercer County, New Jersey, and surrounding areas, collected by the U.S. Geological Survey through the 1981 water year. Included are descriptions and elevations of floodmarks at 30 sites located by the West Windsor Township...
Digital model of the Bates Creek alluvial aquifer near Casper, Wyoming
K. C. Glover
1982, Water-Resources Investigations Report 82-4068
A digital model was used to simulate ground-water flow within the Bates Creek alluvial aquifer, southwest of Casper, Wyoming. Hydrologic data collected during 1977 and 1978 were used to develop the flow model under steady-state and transient conditions. Three scenarios for operating the stream-aquifer system were evaluated with the digital...
Model modifications for simulation of flow through stratified rocks in eastern Ohio
J. O. Helgesen, A. C. Razem, S. P. Larson
1982, Water-Resources Investigations Report 82-4019
A quasi three-dimensional groundwater flow model is being used as part of a study to determine impacts of coal-strip mining on local hydrologic systems. Modifications to the model were necessary to simulate local hydrologic conditions properly. Perched water tables required that the method of calculating vertical flow rate be changed....
