Effect of the proposed Cooper River rediversion on sedimentation in Charleston Harbor, South Carolina
G. G. Patterson
1983, Water-Resources Investigations Report 83-4198
The rates of sedimentation and of resultant maintenance dredging in Charleston Harbor increased dramatically in the 1940s, following two major modifications to the harbor. One modification, the Santee-Cooper diversion project, caused a twentyfold increase in freshwater inflow to the harbor. The other modification was deepening of the navigation channels in...

S. C. Christenson
1983, Water-Resources Investigations Report 83-4076
Alluvium and terrace deposits of Quaternary age, which cover an area of about 400 square miles along the North Canadian River between Canton Lake and Lake Overholser, locally yield as much as 500 gallons per minute to wells. The deposits are as much as 100 feet thick and consist of...
Geology of the "20-foot" clay and Gardiners clay in southern Nassau and southwestern Suffolk counties, Long Island, New York
T.P. Doriski, Franceska Wilde-Katz
1983, Water-Resources Investigations Report 82-4056
Data from 1978-79 drilling was compiled with information from previous reports and historical records to prepare surface contour and isopach maps of the ' 20-foot ' clay and Gardiners Clay in southern Nassau and southwestern Suffolk Counties. These units are major confining layers in the upper part of the groundwater...
Depth to the water table (1976-1977) in the Greater Denver area, Front Range urban corridor, Colorado
D. E. Hillier, P. A. Schneider Jr., E. C. Hutchinson
1983, IMAP 856-K
Knowledge of the depth to the water table is useful to State and local officials in making decisions on land use in the rapidly urbanizing greater Denver are. This report presents the results of a 2-year investigation to determine the depth to the water table, water-table fluctuations and trends, and to relate...
Improvement of flood-frequency estimates for selected small watersheds in eastern Kansas using a rainfall-runoff model
R.W. Clement
1983, Water-Resources Investigations Report 83-4110
The U.S. Geological Survey rainfall-runoff model was used to estimate model parameters for 13 small watersheds in eastern Kansas with drainage areas of less than 11 square miles. Model parameters and rainfall data from three long-term rainfall stations were used in the model to synthesize long-term records of simulated annual...
Hydrology of Area 61, Northern Great Plains and Rocky Mountain Coal Provinces, Colorado and New Mexico
P.O. Abbott, Arthur L. Geldon, Doug Cain, Alan P. Hall, Patrick Edelmann
1983, Water-Resources Investigations Report 83-132
Area 61 is located on the Colorado-New Mexico boundary in Huerfano and Las Animas Counties, Colorado, and Colfax County, New Mexico, and includes the Raton Mesa coal region. The 5 ,900-square-mile area is an asymmetrical structural trough bounded by the Rocky Mountains on the west and the Great Plains on...
Chronology of late Pleistocene and Holocene volcanics, Long Valley and Mono Basin geothermal areas, eastern California
S. H. Wood
1983, Open-File Report 83-747
Hydration-rind ages based on hydration-rind thicknesses of obsidian and an assumed hydration rate of 5 microns /1000 yrs have been determined for the 26 exposed Mono domes and coulees. Hydration-rind thickness data give good estimates of relative age differences between the domes, but determination of absolute ages will depend upon...
Geophysical and geologic studies in southern Mecklenburg County and vicinity, North Carolina and South Carolina
Frederick A. Wilson
1983, Open-File Report 83-93
Geophysical methods consisting of gravity, aeromagnetics and aeroradioactivity have been applied to part of the Charlotte and Carolina slate belts in southern Mecklenburg County and vicinity to help interpret geology, lithology and structure. High aeroradioactivity is associated with potassium-rich granitic plutons, muscovite-rich gneisses, schists, and metavolcanic rocks; positive gravity and...
