Water resources data, Louisiana, water year 1981, volume 1. Central and northern Louisiana
Water Resources Division, U.S. Geological Survey
1981, Water Data Report LA-81-1
Water resources data for the 1981 water year for Louisiana consist of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels and water quality of ground water. This report, in three volumes, contains records for water discharge at...
Evaluation of radar imagery for geological and cartographic applications
Gerald K. Moore, Cynthia A. Sheehan
1981, Open-File Report 81-1358
The House/Senate conference report on H.R. 4930 (96th Congress), the Department of the Interior and Related Agencies Appropriations bill, 1980, stated that the U.S. Geological Survey should "begin the use of side-looking airborne radar imagery for topographic and geological mapping, and geological resource surveys in promising areas, particularly Alaska." In...
Hydrologic data for the Cache Creek-Bear Thrust environmental impact statement near Jackson, Wyoming
G.S. Craig Jr., B. H. Ringen, E.R. Cox
1981, Open-File Report 81-410
Information on the quantity and quality of surface and ground water in an area of concern for the Cache Creek-Bear Thrust Environmental Impact Statement in northwestern Wyoming is presented without interpretation. The environmental impact statement is being prepared jointly by the U.S. Geological Survey and the U.S. Forest Service and...
Cooperative tectonic studies from seismic network in central Italy
L. Seeber, C.H. Scholz
1981, Open-File Report 81-92
The purpose of the subject contract work was to explore the possibility of tectonic research-work based on seismic data from a local network carried out as a cooperative effort between the Institute Nazionale di Geofisica (ING), Rome, and Columbia University (L-DGO), New York. This effort has been rather successful, and...
Water resources data for Florida, water year 1980; Volume 3A. Southwest Florida surface water
Water Resources Division, U.S. Geological Survey
1981, Water Data Report FL-80-3A
Water resources data for the 1980 water year for southwest Florida consist of records of stage, discharge, and water quality of streams; elevation and water quality of lakes and reservoirs; water-levels and water quality of wells; and discharge and water quality of springs. Additional water data were collected at various...
Mathematical model of gamma-ray spectrometry borehole logging for quantitative analysis
Ulrich Schimschal
1981, Open-File Report 81-402
A technique for analyzing gamma-ray spectral-logging data has been developed, in which a digital computer is used to calculate the effects of gamma-ray attentuation in a borehole environment. The computer model allows for the calculation of the effects of lithology, porosity, density, and the thickness of a horizontal layer of...
Quantitative geomorphology of drainage basins in Sumter National Forest, South Carolina
Glenn G. Patterson
1981, Open-File Report 81-417
This report describes a computer program, written in Basic, that facilitates quantitative analysis of drainage basins and channel networks. The program was used to inventory 2,000 small watersheds in Sumter National Forest, South Carolina during 1980 and 1981. Drainage basins and stream segments were delineated in color on mylar overlays...
Potentially favorable areas for large-yield wells in the Red River Formation and Madison Limestone in parts of Montana, North Dakota, South Dakota, Wyoming, and Nebraska
L.M. MacCary, E. M. Cushing, David L. Brown
1981, Open-File Report 81-220
The need for large quantities of energy has created interest in the Fort Union coal region of the Northern Great Plains. Extensive development of this coal, which may include onsite steam-power generation, gasification, liquefaction, and slurry-pipeline transport of the coal from this region, would place a heavy demand on the...
Simulated interactions between the proposed Narrows Reservoir and the water-table aquifer along the South Platte River, Morgan County, Colorado
Alan W. Burns
1981, Water-Resources Investigations Report 80-119
A computer model, including a ground-water-flow component and a mass balance reservoir-operations component, was developed to simulate the proposed Narrows Reservoir and the adjacent alluvial aquifer of the South Platte River, Morgan County, Colo. This model, using a weekly time step, simulated the transient interactions of these two systems for...
Selected hydrogeologic data from the Northern Great Plains area of Montana
Gary W. Levings
1981, Open-File Report 81-534
Selected hydrologic data have been used in a 4-year study of aquifers of Cenozoic and Mesozoic age in the northern Great Plains to define the hydrologic system and to generate hydrologic maps. Records of 6,754 wells and 188 springs are tabulated in the report. The well data include site location,...
Selected drill-stem-test data from the Northern Great Plains area of Montana
Gary W. Levings
1981, Open-File Report 81-326
Selected drill-stem-test data were collected for use in the hydrologic analysis of aquifers in the northern Great Plains area of Montana. To supplement existing data defining the potentiometric surface of various aquifers, shut-in pressures recorded during drill-stem tests of oil and gas test wells were used to calculate the altitude...
Preliminary design study for a National Digital Seismograph Network
Jon Peterson, Charles R. Hutt
1981, Open-File Report 81-1046
Recently, the National Research Council published a report by the Panel on National, Regional, and Local Seismograph Networks of the Committee on Seismology in which the principal recommendation was for the establishment of a national digital seismograph network (NDSN). The Panel Report (Bolt, 1980) addresses both the need and the...
High-resolution seismic-reflection profiles from the Duxbury, Massachusetts, area
Kenneth F. Parolski
1981, Open-File Report 81-358
In August 1980, The U.S. Geological Survey conducted a seismic study (fig. 1) of the harbor and nearshore waters of Duxbury, Massachusetts, aboard the 38' research vessel R/V NEECHO. In all, 18.5 kilometers of high-resolution seismic profiles and sidescan-sonar data were obtained.The systems used included an 80-J minisparker and an...
Revised techniques for estimating magnitude and frequency of floods in Montana
Charles Parrett, R. J. Omang
1981, Open-File Report 81-917
Relations for estimating the flood magnitudes for ungaged sites in Montana have been updated. The State was divided into eight regions and separate multiple-regression equations for each region were developed that relate logarithms of annual flood magnitude to logarithms of basin characteristics for exceedance probabilities of 50, 20, 10, 4,...
Petrogenetic modeling of a potential uranium source rock, Granite Mountains, Wyoming
J. S. Stuckless, A.T. Miesch
1981, Professional Paper 1225
Previous studies of the granite of Lankin Dome have led to the conclusion that this granite was a source for the sandstone-type uranium deposits in the basins that surround the Granite Mountains, Wyo. Q-mode factor analysis of 29 samples of this granite shows that five bulk compositions are required to...
