Regional hydrology of the Green River-Moab area, northwestern Paradox basin, Utah
F. E. Rush, M.S. Whitfield, I. M. Hart
1982, Open-File Report 82-107
The Green River-Moab area encompasses about 7,800 square kilometers or about 25 percent of the Paradox basin. The entire Paradox basin is a part of the Colorado Plateaus that is underlain by a thick sequence of evaporite (salt) beds of Pennsylvanian age. The rock units that underlie the area have...
Hydrology of the Arbuckle Mountain area, south-central Oklahoma
Roy W. Fairchild, Ronald L. Hanson, Robert E. Davis
1982, Open-File Report 82-775
Rocks that make up the Arbuckle-Simpson aquifer crop out over about 500 square miles in the Arbuckle Mountains province in south-central Oklahoma. The aquifer consists of limestone, dolomite, and sandstone of the Arbuckle and Simpson Groups of Late Cambrian to Middle Ordovician age and is about 5,000 to 9,000 feet...
Ground-water levels in selected well fields and in west-central Florida, September 1981
D. K. Yobbi, G. L. Barr
1982, Open-File Report 82-261
The water table in the surficial aquifer and the potentiometric surface of the Floridan aquifer in a 1,200-square-mile area in west-central Florida are mapped semiannually by the U.S. Geological Survey. Maps are based on water levels measured in wells each May to coincide with seasonal low levels and each September...
Hydrotectonics; principles and relevance
R. W. Kopf
1982, Open-File Report 82-307
Hydrotectonics combines the principles of hydraulics and rock mechanics. The hypothesis assumes that: (1) no faults are truly planar, (2) opposing noncongruent wavy wallrock surfaces form chambers and bottlenecks along the fault, and (3) most thrusting occurs beneath the water table. These physical constraints permit the following dynamics. Shear displacement...
Hydrologic data from Naval Oil Shale Reserves, Parachute Creek basin, northwestern Colorado, 1975-79
Ralph O. Patt, D. Briane Adams, Dannie L. Collins
1982, Open-File Report 82-696
This report summarizes data collected by the U.S. Geological Survey for the U.S. Department of Energy, Naval Petroleum, and Oil Shale Reserves in the Parachute Creek drainage basin of western Colorado. It includes data from five surface-water gages, two automatic sediment samplers and two water-quality monitors. Instantaneous streamflow measurements were...
Radioactivity and geochemistry of selected mineral-spring waters in the Western United States; basic data and multivariate statistical analysis
J.K. Felmlee, R. A. Cadigan
1982, Open-File Report 82-324
Multivariate statistical analyses were performed on data from 156 mineral-spring sites in nine Western States to analyze relationships among the various parameters measured in the spring waters. Correlation analysis and R-mode factor analysis indicate that three major factors affect water composition in the spring systems studied: (1) duration of water...
Hydrologic data for urban studies in the Houston, Texas, metropolitan area, 1979
Fred Liscum, Jay F. Weigel, J.P. Bruchmiller
1982, Open-File Report 82-164
Hydrologic investigations of urban watersheds in Texas were begun by the U.S. Geological Survey in 1954. Studies are now in progress in Austin, Houston, and San Antonio.The U.S. Geological Survey, in cooperation with the city of Houston, began studies in the Houston metropolitan area in 1964. The program was expanded...
Preliminary data for northern Great Plains test well 1, quarter NE quarter Sec. 11, T.55N., R.77W., Sheridan County, Wyoming
D.H. Lobmeyer, L. O. Anna, J.F. Busby
1982, Open-File Report 82-446
This report documents the preliminary data obtained from Northern Great Plains test well 1 and describes the preliminary results and future testing plans. The intended audience includes hydrologists, local water users, drilling contractors, and water managers. The test well was drilled as part of the study to determine the water...
