Hydrologic relations between lakes and aquifers in a recharge area near Orlando, Florida
William F. Lichtler, G.H. Hughes, F. L. Pfischner
1976, Water-Resources Investigations Report 76-65
The three lakes investigated in Orange County, Florida, gain water from adjoining water-table aquifer and lose water to Floridan aquifer by downward leakage. Net seepage (net exchange of water between lake and aquifers) can be estimated by equation S = AX + BY, where S is net seepage, X represents...
Mapping and measuring land-cover characteristics of New River Basin, Tennessee, using Landsat digital tapes
E. F. Hollyday, S.P. Sauer
1976, Water-Resources Investigations Report 76-106
Land-cover information is needed to select subbasins within the New River basin, Tennessee, for the study of hydrologic processes and also is needed to transfer study results to other sites affected by coal mining. It was believed that data recorded by the first Earth Resources Technology Satellite (Landsat-1) could be...
Hydrology of the Princeton area, Kentucky
R. O. Plebuch
1976, Water-Resources Investigations Report 76-43
The Princeton area comprises about 155 square miles in western Kentucky and includes parts of Caldwell, Crittenden, and Lyon Counties. The area is in the Mississippi Plateau region of Kentucky and lies within the drainage basin of the Cumberland River and Tradewater River basins. In 1974 municipal water-supply systems utilized...
Effects of off-road vehicle use on the hydrology and landscape of arid environments in central and southern California
Charles T. Snyder, D. G. Frickel, R. F. Hadley, R.F. Miller
1976, Water-Resources Investigations Report 76-99
Two widely separated sites in California used for motorcycle hill-climbing were studied to evaluate the impact on the landscape and hydrology. At Panoche Hills in central California, an area formerly used by motorcycles together with an adjacent unused area were monitored from 1971 to 1975. Observations in both areas included...
Basic data from five core holes in the Raft River geothermal area, Cassia County, Idaho
E. G. Crosthwaite (compiler)
1976, Open-File Report 76-665
Studies of the geothermal aspect-of the Bridge area of the Raft River basin in south-central Idaho (fig. 1) by the U.S. Geological Survey began in 1972 when Young and Mitchell (1973) made a geochemical and geologic reconnaissance of selected thermal waters in Idaho. The Bridge area had been designated the...
Hydrologic reconnaissance of the geothermal area near Klamath Falls, Oregon
E.A. Sammel, D. L. Peterson
1976, Water-Resources Investigations Report 76-127
Geothermal phenomena observed in the vicinity of Klamath Falls include hot springs with temperatures that approach 204°F (96 o C) (the approximate boiling temperature for the altitude), steam and water wells with temperatures that exceed 212°F (100°C), and hundreds of warm-water wells with temperatures mostly ranging from 68° to 95°F...
Model analysis of effects on water levels at Indiana Dunes National Lakeshore caused by construction dewatering
James R. Marie
1976, Water-Resources Investigations Report 76-82
Two computer models were developed to investigate possible hydrologic effects within the Indiana Dunes National Lakeshore caused by planned dewatering at the adjacent Bailly Nuclear Generator construction site. The dewatering, which is scheduled to last for about 18 months, would cause ground-water levels to be drawn down 20 to 30...
Geohydrology of the Albin and La Grange areas, aoutheastern Wyoming
W. B. Borchert
1976, Water-Resources Investigations Report 76-118
The Albin and La Grange areas in southeastern Wyoming are two adjoining different hydrologic areas. Since ground water is the only source of water for irrigation in the Albin area, 34 irrigation wells have been drilled since 1968 and developed in conjunction mostly with center-pivot sprinkler systems that in 1974...
Magnitude and frequency of floods in Nebraska
Emil W. Beckman
1976, Water-Resources Investigations Report 76-109
Estimates of flood characteristics with recurrence intervals up to 100 years can be obtained at most sites in Nebraska by use of techniques presented in this report. Instructions, equations, and graphs are presented to aid the design engineer in estimating the magnitude and frequency of floods. For natural-flow streams, the estimating...
Distribution functions for statistics derived from bivariate normal and bivariate two-parameter log-normal populations
James Richard Slack, Nicholas C. Matalas, James R. Wallis
1976, Open-File Report 76-214
The distribution functions for hydrologic statistics that may be used to assess the significance of differences between sample means, standard deviations, coefficients of skewness, and coefficients of variations are obtained by Monte Carlo experiments. The distributions are expressed as functions of sample size, cross correlation, and skewness. In general, the...
Status of ground-water modeling in the U.S. Geological Survey
Charles A. Appel, J.D. Bredehoeft
1976, Circular 737
The U.S. Geological Survey is active in the development and use of models for the analysis of various types of ground-water problems. Types of problems for which models have been, or are being, developed include: (1) ground-water flow in saturated or partially unsaturated materials, (2) land subsidence resulting from ground-water...
Hydrologic interpretation of geophysical data from the southeastern Hueco Bolson, El Paso, and Hudspeth Counties, Texas
Joseph Spencer Gates, W. D. Stanley
1976, Open-File Report 76-650
Airborne-electromagnetic and earth-resistivity surveys were used to explore for fresh ground water in the Hueco Bolson southeast of El Paso, Texas. Aerial surveys were made along about 500 miles (800 km) of flight line, and 67 resistivity soundings were made along 110 miles (180 km) of profile. The surveys did...
Data for calibrating unsteady-flow sediment-transport models, East Fork River, Wyoming, 1975
Holly A. Mahoney, Edmund D. Andrews, William W. Emmett, Luna Bergere Leopold, Robert H. Meade, Robert M. Myrick, Carl F. Nordin
1976, Open-File Report 76-22
In 1975, data to calibrate a one-dimensional unsteady-flow and sediment-transport routing model were collected on a reach of the East Fork River of western Wyoming. The reach, 3.1 miles (5 kilometers) in length, wan immediately upstream from a previously established bedload sampling station. Nineteen channel cross sections were sounded at...
Geochemical and hydrologic data for wells and springs in thermal-spring areas of the Appalachians
W.A. Hobba, J.C. Chemerys, D.W. Fisher, F. J. Pearson Jr.
1976, Open-File Report 76-550
Current interest in geothermal potential of thermal-spring areas in the Appalachians makes all data on thermal springs and wells in these areas valuable. Presented here without interpretive comment are maps showing selected springs and wells and tables of physical and chemical data pertaining to these wells and springs. The chemical...
