Summary appraisals of the nation's ground-water resources – Arkansas-White-Red region
M. S. Bedinger, R. T. Sniegocki
1976, Professional Paper 813-H
The Arkansas-White-Red Region, an area of265,000 square miles (6.86x1011 square metres), is characterized by diversity in geography, climate, and geology and, in turn, by diversity in water resources and water problems. The western semiarid part of the region is water deficient, that is, potential evapotranspiration exceeds precipitation. The eastern, humid part...
Geological Survey research 1976
Water Resources Division, U.S. Geological Survey
1976, Professional Paper 1000
This U.S. Geological Survey activities report includes a summary of recent (1976 fiscal year) scientific and economic results accompanied by a list of geologic and hydrologic investigations in progress and a report on the status of topographic mapping. The summary of results includes: (1) Mineral resources, Water resources, (2) Engineering...
Summary appraisals of the nation's ground-water resources–Texas-Gulf region
E. T. Baker Jr., J. R. Wall
1976, Professional Paper 813-F
Ground water in the Texas-Gulf Region is a large and important resource that can provide a more significant percentage of the total water supply of the region. Total water requirements within the region are projected to rise sharply from 14 million acre-feet (17 cubic kilometres) in 1970 to nearly 26...
Analysis of seismograms from a downhole array in sediments near San Francisco Bay
William B. Joyner, Richard E. Warrick, Adolph A. Oliver III
1976, Open-File Report 76-296
A four-level downhole array of three-component instruments was established on the southwest shore of San Francisco Bay to monitor the effect of the sediments on low-amplitude seismic ground motion. The deepest instrument is at a depth of 186 meters, two meters below the top of the Franciscan bedrock. Earthquake data...
Evaluation of hydrologic properties of the Long Island ground-water reservoir using cross-sectional electric-analog models
O.L. Franke, R.T. Getzen
1976, Open-File Report 75-679
Variables necessary for constructing a quantitative model to predict the response of ground-water reservoirs to hydrologic stresses are in four classes: (a) external and internal geometry of the reservoir, (b) nature of the reservoir boundaries, (c) areal distribution of horizontal and vertical hydraulic conductivities, and (d) areal distribution of storage...
FORTRAN computer program for seismic risk analysis
Robin K. McGuire
1976, Open-File Report 76-67
A program for seismic risk analysis is described which combines generality of application, efficiency and accuracy of operation, and the advantage of small storage requirements. The theoretical basis for the program is first reviewed, and the computational algorithms used to apply this theory are described. The information required for running...
Report on the environmental geology OCS area, eastern Gulf of Alaska
Bruce F. Molnia, Paul R. Carlson, Terry R. Bruns
1976, Open-File Report 76-206
In anticipation of oil and gas leasing of the outer continental shelf (OCS lease area 39) in the northeastern Gulf of Alaska, the U. S. Geological Survey began a regional reconnaissance in 1974. The study area, which extends from Prince William Sound on the west to Yakutat Bay on the...
A study of the mineralogy and lithology of cuttings from the U.S. Bureau of Reclamation MESA 6-2 Drillhole, Imperial County, California, including comparisons with MESA 6-1 Drillhole
R.B. Fournier
1976, Open-File Report 76-88
The Mesa 6-2 drillhole penetrates 6,000 feet of sediments in Imperial County, California. The cuttings material from the upper part of the drillhole is chiefly unconsolidated mud and silt. Soft siltstone fragments occur at about 1,400 feet and increase in amount down to 2,400 feet. Some pebbles are found above...
