Weather forecast needs from the viewpoint of hydrology
Donald M. Thomas, Thomas J. Buchanan
1980, Open-File Report 80-754
Hydrologists now depend on directly observed data in their forecasting and only infrequently use meteorological forecasts. Case studies show how reliable meteorological forecasts could be beneficial in flood and drought situations. Hydrologists need meteorological forecasts that recognize spatial variability, that are unbiased, and that have a specified degree of uncertainty....
Analyses of water and dredged material from selected southern Louisiana waterways and selected areas in the Gulf of Mexico, 1976-78
Geraldine R. Stallworth, Helen F. Jordan
1980, Open-File Report 80-694
The U.S. Geological Survey was requested by the U.S. Army Corps of Engineers to provide water-quality data to evaluate the potential environmental effects of (1) dredging activities in selected navigable waterways of southern Louisiana and (2) the disposal of dredged material at selected areas in the Gulf of Mexico. Areas...
Sulfate reduction in ground water of southeastern Montana
William S. Dockins, G.J. Olson, Gordon A. McFeters, S.C. Turbak, Roger W. Lee
1980, Water-Resources Investigations Report 80-9
Ground water in southeastern Montana was investigated to determine if sulfide production was bacterially mediated. Sulfate—reducing bacteria were detected in 25 of 26 ground—water samples in numbers ranging from 2.0 x 101 to greater than 2.4 x 104 bacteria per 100 milliliters. Stable sulfur isotope fractionation studies indicate a biological...
Initial report of the petrophysics laboratory; 1977-1979 addendum
Gary R. Olhoeft
1980, Open-File Report 80-522
From the time the author-copy of Circular 789 (Hunt and others, 1979) was prepared until it first appeared in print, significant changes occurred in the Petrophysics Laboratory. To update that report, this open-file report will briefly summarize more recent acquisitions and facilities changes....
Digital-computer model of ground-water flow in Tooele Valley, Utah
Allan C. Razem, Scott D. Bartholoma
1980, Open-File Report 80-446
A two-dimensional, finite-difference digital-computer model was used to simulate the ground-water flow in the principal artesian aquifer in Tooele Valley, Utah. The parameters used in the model were obtained through field measurements and tests, from historical records, and by trial-and-error adjustments. The model was calibrated against observed water-level changes that...
Dinkum Sands
Erk Reimnitz, Robin Ross, Peter W. Barnes
1980, Open-File Report 80-360
The State/Federal Beaufort Sea lease sale in December 1979 attracted over one billion dollars in bids. Tracts with the highest bids, and apparently with the highest oil potential, lie in the area south of Dinkum Sands, and within a three-mile radius of the shoal (Fig. 1). Jurisdiction over the tracts...
Quality of surface water in the coal-mining region, southwestern Indiana, March and May 1979
Danny E. Renn, Stephen E. Ragone, William G. Wilber
1980, Open-File Report 80-970
On August 3, 1977, the Surface Mine Control and Reclamation Act, Public Law 95-87 (the Act) was enacted by the 95th Congress. Under Section 507(b)(11) of the Act, an appropriate Federal or State agency must provide applicants for coal-mining permits hydrologic and water-quality information for the general use of proposed...
Map showing the Elko crater field, Elko County, Nevada
Keith B. Ketner, David J. Roddy
1980, Miscellaneous Field Studies Map 1168
The Elko crater field consists of two arrays of rimmed craters in the valleys of Dorsey, Susie, and McClellan Creeks, 30 to 50 km north of Elko, Nevada. In the principal array, more the 165 craters are scattered irregularly in an area 3 km wide and 20 km long. Most...
Seismicity map of the State of Michigan
C. W. Stover, B.G. Reagor, S. T. Algermissen
1980, Miscellaneous Field Studies Map 1228
The earthquake data shown on this map and listed in table 1 are a list of earthquakes that were originally used in preparing the Seismic Risk Studies in the United States in the United States (Algermissen, 1969) which have been recompiled and updated through 1977.  These data have been reexamined...
