Hydrology of three sinkhole basins in southwestern Seminole County, Florida
Warren Anderson, G.H. Hughes
1975, Open-File Report 75-27
The southwestern part of Seminole County--in east-central Florida-is characterized by sinkholes formed by the subsidence of surficial deposits into solution cavities in the underlying limestone deposits. The area includes three sinkhole basins created by such subsidence: Cranes Roost, Palm Springs, and Grace Lake.Cranes Roost basin (drainage area, 5.02 square miles)...
A water-quality assessment of the Jordan Creek watershed, Warren County, Indiana
Mark A. Ayers
1975, Open-File Report 75-323
A water-quality assessment of the Jordan Creek watershed was made September 24 and 25, 1974. Surface waters within the watershed were calcium bicarbonate types with very similar concentrations of major dissolved constituents and specific conductance values. Streamwaters contained less than 0.26 milligram per litre dissolved nitrate (as N), 0.03 milligram...
A Study of earthquake losses in the Puget Sound, Washington, area
Water Resources Division, U.S. Geological Survey
1975, Open-File Report 75-375
The Puget Sound Basin has a history of frequent seismic activity, including two recent damaging events. The greatest extent of urban development and the most densely populated area generally correspond to the area where the greatest energy release has been experienced. For this study two earthquakes have been simulated, each...
Preliminary report on the use of LANDSAT-1 (ERTS-1) reflectance data in locating alteration zones associated with uranium mineralization near Cameron, Arizona
Charles S. Spirakis, Christopher D. Condit
1975, Open-File Report 75-416
LANDSAT-I (ERTS-I) multispectral reflectance data were used to enhance the detection of alteration around uranium deposits near Cameron, Ariz. The technique involved stretching and ratioing computer-enhanced data from which electronic noise and atmospheric haze had been removed. Using present techniques, the work proves that LANDSAT-I data are useful in detecting...
Sources of emergency water supplies in San Mateo County, California
P.R. Wood
1975, Open-File Report 75-43
San Mateo County has several densely populated urban areas that get most of their water supplies from surface-water sources that could by damaged by a major earthquake or other general disaster. In the event of such a disaster, limited supplies of potable water may be obtained from selected wells, springs,...
Relation of precipitation to annual ground-water recharge in the Edwards Aquifer, San Antonio area, Texas
Celso Puente
1975, Open-File Report 75-298
Annual recharge data obtained from historical records and mean-annual precipitation data computed from rainfall records were used to develop simple linear-regression equations for use in estimating annual recharge for seven subbasins in the San Antonio area. Adjustments were made to the precipitation parameter to account for the effects of year-end...
