Hydrogeologic data for selected coal areas, east-central Montana
Robert S. Roberts
1980, Open-File Report 80-329
Hydrogeologic data were collected in selected coal areas of east-central Montana to provide a basis for evaluating the effects of future coal development on the groundwater resources. Inventory records for 916 domestic, stock, public supply, commercial, and test wells are tabulated in the report; the data were collected principally from...
Mount St. Helens ash fall in the Bull Run watershed, Oregon, May-June 1980
Michael V. Shulters, Daphne G. Clifton
1980, Open-File Report 80-593
On May 25-26, May 30-June 2, and June 12-13, 1980, strong, high-altitude winds from the north occurred during periods of volcanic-ash eruption at Mount St. Helens in southwestern Washington. As a result, ash fell in the Bull Run watershed, Oregon, some 50 miles to the south, the principal water-supply source...
Hydrology and geochemistry of thermal ground water in southwestern Idaho and north-central Nevada
H.W. Young, R.E. Lewis
1980, Open-File Report 80-2043
In southwestern Idaho and north-central Nevada, thermal groundwater occurs under artesian conditions in igneous or sedimentary rocks of Tertiary age. Temperatures of the groundwater range from 30 degrees to more than 80 degrees Celsius. Thermal waters are a sodium carbonate or bicarbonate type; nonthermal waters are a calcium bicarbonate. Chemical...
Quality of water and time of travel in Yockanookany River, Choctaw County, Mississippi
Gene A. Bednar
1980, Open-File Report 80-770
An intensive study of a 3.3-mile reach of the Yockanookany River, including a major tributary, was conducted August 29-31, 1978. The quality-of-water data were collected during a period of generally law streamflow and seasonally high air temperatures. These data show that the quality of water in Yockanookany River was generally...
Seismic-reflection data on the eastern U.S. continental shelf acquired by M. V. L'OLONNOIS as part of the Atlantic Margin Coring Project (AMCOR) of the U.S. Geological Survey, July-September 1976
James M. Robb
1980, Open-File Report 80-369
In 1976 the U.S. Geological Survey undertook a program to sample the eastern United States Shelf for stratigraphic information by drilling a set of core holes. Results of this Atlantic Margin Coring Program (AMCOR) have been reported by Hathaway and others. Sites were chosen from seismic-reflection data and were reviewed...
Geologic and operational summary, COST no. G-1 well, Georges Bank area, North Atlantic OCS
Roger V. Amato, John W. Bebout, editor(s)
1980, Open-File Report 80-268
The first Continental Offshore Stratigraphic Test (COST) well on the U.S. North Atlantic Outer Continental Shelf (OCS) was drilled by Ocean Production Company between April 6 and July 26, 1976, and designated the COST No. G-1. Geological and engineering data obtained from this deep well in the Georges Bank Basin...
The oilspill risk analysis model of the U. S. Geological Survey
R. A. Smith, J. R. Slack, T. Wyant, K.J. Lanfear
1980, Open-File Report 80-687
The U.S. Geological Survey has developed an oilspill risk analysis model to aid in estimating the environmental hazards of developing oil resources in Outer Continental Shelf (OCS) lease areas. The large, computerized model analyzes the probability of spill occurrence, as well as the likely paths or trajectories of spills in...
Integrated uranium system in the Marysvale volcanic field, west-central Utah
Thomas August Steven, Charles G. Cunningham, Michael N. Machette
1980, Open-File Report 80-524
Uranium in the Marysvale volcanic field is known to occur in several geologic environments, and is hypothesized to occur in others. Together the known and hypothetical occurrences range from a source in rhyolite magma, through porphyry-type deposits, hydrothermal vein deposits, dispersed hydrothermal deposits, and after transport in ground and surface...
A practical Lagrangian transport model
Harvey E. Jobson
1980, Open-File Report 80-206
An unconditionally stable and practical transport model for use in upland streams and rivers has been developed and verified. Basing the model on the Lagrangian, rather than the Eulerian, reference frame greatly reduces the numerical problems associated with solving the advective terms of the convective-diffusion equation. The model contains almost...
