1980, Open-File Report 80-283
Two hundred twenty-four kilometers of closely spaced side-scan sonograph data have been collected from eastern Rhode Island Sound and Vineyard Sound, Mass., by the U.S. Geological Survey in cooperation with the New England Division of the U.S. Army Corps of Engineers. These data were obtained during the August 1976 cruise...
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...

Extension of transient-flow model of the Sacramento River at Sacramento, California
Richard N. Oltmann
1980, Water-Resources Investigations Report 80-30
The multiple-reach method-of-characteristics flow-simulaltion model that was successfully applied in 1976 to a 10.8-mile tide-affected reach of the Sacramento River, in California, from Sacramento to Freeport has been extended 10.5 miles farther downstream of Hood. The model reach was extended to improve the quality of the model 's output during...

1980, Open-File Report 80-435
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...
Hydrology and model study of the proposed Prosperity Reservoir, Center Creek Basin, southwestern Missouri
Edward Joseph Harvey, Leo F. Emmett
1980, Water-Resources Investigations Report 80-7
A dam and reservoir have been proposed for construction on Center Creek, Jasper County, in southwestern Missouri. Ground-water levels in the hills adjacent to the reservoir will rise when the impoundment is completed. One of the problems is that the proposed site of Prosperity Reservoir is a few miles upstream...

Ground-water availability and water quality in Farmington, Connecticut
David L. Mazzaferro
1980, Open-File Report 80-751
The strataified-drift aquifer in Farmington, Conn., is capable of yielding large amounts of water to individual wells. About 14 square miles of Farmington is underlain by stratified-drift deposits which, in places, are more than 450 feet thick. The most productive deposits are found in the Farmington River valley, from Unionville...
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...

Appraisal of ground-water resources in the San Antonio Creek Valley, Santa Barbara County, California
C. B. Hutchinson
1980, Open-File Report 80-750
A nearly threefold increase in demand for water in the 154-square-mile San Antonio Creek valley in California during the period 1958-77 has increased the potential for overdraft on the ground-water basin. The hydrologic budget for this period showed a perennial yield of about 9,800 acre-feet per year and an annual...
Ground water availability in Acadia National Park and vicinity, Hancock and Knox counties, Maine
Bruce P. Hansen
1980, Open-File Report 80-1050
In general, yield of water from individual wells in unconsolidated surficial deposits is low (0-10 gallons per minute). Several small, unconsolidated deposits may yield moderate quantities (50-100 gallons per minute) but these have not been adequately tested.Yields from 160 wells in the crystalline bedrock range from 0.5 gallons per minute...
A limnological study of 43 selected Maine lakes
Derrill J. Cowing, Matthew Scott
1980, Water-Resources Investigations Report 80-69
Federal and State legislation require the trophic classification of lakes and ponds in the State of Maine as part of a lake management program. In 1974, the State of Maine Department of Environmental Protection (DEP) adopted a preliminary set of procedures for establishing an index of lake trophic status. Also...
Interactive computer methods for generating mineral-resource maps
James Alfred Calkins, A.S. Crosby, T.E. Huffman, A. L. Clark, G.T. Mason, R.J. Bascle
1980, Circular 815
Inasmuch as maps are a basic tool of geologists, the U.S. Geological Survey's CRIB (Computerized Resources Information Bank) was constructed so that the data it contains can be used to generate mineral-resource maps. However, by the standard methods used-batch processing and off-line plotting-the production of a finished map commonly takes...

P.M. Merifield, D.L. Lamar
1980, Open-File Report 81-386
Beginning in October 1976, a program of water-level monitoring of abandoned water wells was initiated in the Palmdale area with the purpose of identifying possible water-level changes premonitory to a major earthquake on the San Andreas fault. In October 1977, the program was extended southeastward along the rift zone to...

Thomas E. Reilly, Arlen W. Harbaugh
1980, Water-Resources Investigations Report 80-14
A three-dimensional electric-analog model of the Long Island, NY , groundwater system constructed by the U.S. Geological Survey in the early 1970 's was used as the basis for developing a digital, three-dimensional finite-difference model. The digital model was needed to provide faster modifications and more rapid solutions to water-management...

1980, Professional Paper 1170-C
A recent and rapid increase since the mid-1970's in commercial and residential development in the Powder River Basin, Wyoming and Montana, is caused by exploitation of vast coal and other resources in the basin. One geologic hazard to such development is landsliding. A landslide sufficiently representative of others in the...
