Identification codes for organizations listed in computerized data systems of the U.S. Geological Survey
Melvin D. Edwards, Beverly M. Myers
1981, Open-File Report 81-904
This report contains codes for the identification of public and private organizations listed in computerized data systems. These codes are used by the U.S. Geological Survey 's National Water Data Exchange (NAWDEX), National Water Data Storage and Retrieval System (WATSTORE), National Cartographic Information Center (NCIC), and Office of Water Data...
Digital seismograms of aftershocks of the Imperial Valley, California, earthquake of October 15, 1979
Joe B. Fletcher, Ricardo L. Zepeda, David M. Boore
1981, Open-File Report 81-655
This report presents the digital seismograms collected for the aftershocksof the Imperial Valley, California earthquake (ML = 6.6) that occurred onL October 15, 1979. A short summary follows that describes the field procedures, instrumentation, and routine computer analysis that was used to produce the ground motion time histories. Boore and...
Preliminary hydrologic evaluation of the North Horn Mountain coal-resource area, Utah
M.J. Graham, John E. Tooley, Don Price
1981, Open-File Report 81-141
North Horn Mountain is part of a deeply dissected plateau in central Utah which is characterized by deep, narrow, steep-walled canyons with local relief of more than 1,000 feet. Geologic units exposed in the North Horn Mountain area range in age from Late Cretaceous to Holocene and contain two mineable...
Water resources of the Clarion River and Redbank Creek basins, northwestern Pennsylvania
Theodore F. Buckwalter, C.H. Dodge, G. R. Schiner, H.F. Koester
1981, Open-File Report 81-70
The Clarion River and Redbank Creek basin occupy 1,280 and 545 square miles, respectively, in northwatern Pennsylvania. The area is mostly in Clerion, Elk, and Jefferson Counties and is approximately 70 miles long and 30 miles wide. All drainage is to the Allegheny River. Sedimentary...
Hydrologic effects of stress-relief fracturing in an Appalachian Valley
Granville G. Wyrick, James W. Borchers
1981, Water Supply Paper 2177
A hydrologic study at Twin Falls State Park, Wyoming County, West Virginia, was made to determine how fracture systems affect the occurrence and movement of ground water in a typical valley of the Appalachian Plateaus Physiographic Province. Twin Falls was selected because it is generally unaffected by factors that would...
Flow model of Saginaw River near Saginaw, Michigan
David J. Holtschlag
1981, Open-File Report 81-1061
An unsteady-flow simulation model was applied to a 19.5-mile reach of Saginaw River. The model provides a method of determining instantaneous discharge for flows from -8,000 to 12,000 cubic feet per second. The currently used slope-rating method can be utilized to compute discharge only under steady and high-flow conditions. Unsteady...
Erodibility of selected soils and estimates of sediment yields in the San Juan Basin, New Mexico
Rebecca M. Summer
1981, Water-Resources Investigations Report 81-44
Onsite rainfall-simulation experiments were conducted to derive field-erodibility indexes for rangeland soils and soils disturbed by mining in coal fields of northwestern New Mexico. Mean indexes on rangeland soils range from 0 grams (of detached soil) on dune soil to 121 grams on wash-transport zones. Mean field-erodibility-index values of soils...
