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...

Estimating the costs of landslide damage in the United States
Robert W. Fleming, Fred A. Taylor
1980, Circular 832
Landslide damages are one of the most costly natural disasters in the United States. A recent estimate of the total annual cost of landslide damage is in excess of $1 billion {Schuster, 1978}. The damages can be significantly reduced, however, through the combined action of technical experts, government, and the...
A topology of mineralization and its meaning for prospecting
George Joseph Neuerburg
1980, Open-File Report 80-298
Epigenetic mineral deposits are universal members of an orderly spatial-temporal arrangement of igneous rocks, endomorphic rocks, and hydrothermally altered rocks. The association and sequence of these rocks is invariant whereas the metric relations and configurations of the properties of these rocks are unlimited in variety. This characterization satisfies the doctrines...

Ground-water appraisal of sand plains in Benton, Sherburne, Stearns, and Wright counties, central Minnesota
Gerald F. Lindholm
1980, Open-File Report 80-1285
Surficial-sand aquifers in 960 square miles of central Minnesota have been studied to determine the occurrence, availability, and suitability of the surficial aquifer as a source of water. The aquifer is being increasingly developed for irrigation. During the drought of 1976, nearly 24,000 acre-feet of ground water was withdrawn for irrigation,...
Hydrologic monitoring program in Eldridge-Wilde and East Lake Road well-field areas, Pinellas and Hillsborough counties, Florida, 1977 water year
Boyd F. Joyner, James M. Gerhart
1980, Open-File Report 80-345
The observation-well network in the vicinity of the two well fields is described in detail. Data obtained from the network from October 1976 through September 1977, as well as rainfall and pumpage records, are presented and discussed. Below-normal rainfall caused the water table and potentiometric surface of the Floridan aquifer...

The magnitude 5.2 (mb) northern Kentucky earthquake of July 27, 1980, at 18:52:21.8 UTC, located at 38.17N, 83.91W with a depth of 8 km (as determined by the National Earthquake Information Service), was particularly notable for the widespread damage it did, especially to older chimneys. Investigators from several different organizations...

The objectives of the Geological Survey 's river-quality assessment in the Truckee and Carson River basins in California and Nevada are to identify the significant resource management problems; to develop techniques to assess the problems; and to effectively communicate results to responsible managers. Six major elements of the assessment to...
Effects of coal mine subsidence in the Sheridan, Wyoming, area
C. Richard Dunrud, Frank W. Osterwald
1980, Professional Paper 1164
Analyses of the surface effects of past underground coal mining in the Sheridan, Wyoming, area suggest that underground mining of strippable coal deposits may damage the environment more over long periods of time than would modern surface mining, provided proper restoration procedures are followed after surface mining. Subsidence depressions and...

U.S. Geological Survey role in earthquake prediction
David P. Hill
1980, Open-File Report 80-144
Work in the Seismology Branch on the problem of earthquake prediction is based primarily on the recording and analysis of seismic (elastic) waves in the Earth generated either by earthquakes themselves or by artificial sources such as quarry blasts or explosions detonated in drill holes.
