Flood of April 1977 in the Appalachian region of Kentucky, Tennessee, Virginia, and West Virginia
Gerald S. Runner, Edwin H. Chin
1980, Professional Paper 1098
Heavy rains fell over the Appalachian region of Kentucky, Tennessee, Virginia and West Virginia April 2-5, 1977, causing record flooding. Rainfall amounts of 4 to 15.5 inches were observed. The maximum amount of 15.5 inches occurred at Jolo, WV , in about 30 hours. This was more than twice the...

A summary of environmental geologic studies in the Georges Bank area, United States northeastern Atlantic Outer Continental Shelf, 1975-1977
John M. Aaron
1980, Open-File Report 80-241
The growing need for the United States to find and develop new energy resources has led to interest in the petroleum potential of frontier areas of the Atlantic Outer Continental Shelf (OCS) seaward of the eastern seaboard state boundaries. These submerged lands are under federal jurisdiction. The authority to lease...

Recent vegetation changes along the Colorado River between Glen Canyon Dam and Lake Mead, Arizona
Raymond Marriner Turner, Martin M. Karpiscak
1980, Professional Paper 1132
Vegetation changes in the canyon of the Colorado River between Glen Canyon Dam and Lake Mead were studied by comparing photographs taken prior to completion of Glen Canyon Dam in 1963 with photographs taken afterwards at the same sites. In general, the older pictures show an absence of riparian plants...

The Lewis thrust fault and related structures in the Disturbed Belt, northwestern Montana
Melville Rhodes Mudge, Robert L. Earhart
1980, Professional Paper 1174
The classical Lewis thrust fault in Glacier National Park has now been mapped 125 km south of the park to Steamboat Mountain, where the trace dies out in folded middle Paleozoic rocks. The known length of the fault is 452 km, extending northward from Steamboat Mountain to a point 225...
Schlumberger soundings in the Fish Springs Flat area, Juab County, Utah
Robert J. Bisdorf, Adel A. R. Zohdy
1980, Open-File Report 80-384
In 1978 the U. S. Geological Survey made 43 Schlumberger soundings in the Fish Springs Flat area, Juab County, Utah. The purpose of this survey was to delineate water quality and obtain structural information. Fish Springs Flat consists mainly of Quaternery deposits of sand, gravel, clay, and silt. On the...
Digital model simulation of the hydrologic flow system, with emphasis on ground water in Spokane Valley, Washington and Idaho
E.L. Bolke, J.J. Washington
1980, Open-File Report 80-1300
A digital-computer model of the hydrologic flow system, with emphasis on ground water, was developed for Spokane Valley, Washington and Idaho. The current rate of ground-water pumping in Spokane Valley has little effect on water levels in the Spokane aquifer, although short-term water-level declines occur locally. The model was used...

An economic analysis of selected strategies for dissolved-oxygen management; Chattahoochee River, Georgia
John E. Schefter, Robert M. Hirsch
1980, Professional Paper 1140
A method for evaluating the cost-effectiveness of alternative strategies for dissolved-oxygen (DO) management is demonstrated, using the Chattahoochee River, GA., as an example. The conceptual framework for the analysis is suggested by the economic theory of production. The minimum flow of the river and the percentage of the total waste...
A computer program for simulating geohydrologic systems in three dimensions
D.R. Posson, G. A. Hearne, J.V. Tracy, P. F. Frenzel
1980, Open-File Report 80-421
This document is directed toward individuals who wish to use a computer program to simulate ground-water flow in three dimensions. The strongly implicit procedure (SIP) numerical method is used to solve the set of simultaneous equations. New data processing techniques and program input and output options are emphasized. The quifer...
