Saturated thickness of the High Plains regional aquifer in 1980, northwestern Oklahoma
John S. Havens
1982, Open-File Report 82-760
During 1978, the U.S. Geological Survey began a 5-year study of the High Plains regional aquifer system to provide hydrologic information for evaluation of the effects of long-term development of the aquifer and to develop computer models for prediction of aquifer response to alternative changes in ground-water management (Weeks, 1978)....
Hydrology of the Floridan Aquifer in Northwest Volusia County, Florida
A. T. Rutledge
1982, Open-File Report 82-108
Northwest Volusia County, in east-central Florida, is a 262-square-mile area including the southern part of the Crescent City Ridge and the northern tip of the DeLand Ridge. The hydrogeologic units in the area include the Floridan aquifer, which is made up of parts of the Lake City Limestone, the Avon...
Multielement chemical and statistical analyses from a uranium hydrogeochemical and stream-sediment survey in and near the Elkhorn Mountains, Jefferson County, Montana. Part I: Surface water
V. J. Suits, K. J. Wenrich
1982, Open-File Report 82-203-A
Fifty-two surface-water samples, collected from an area south of Helena, Jefferson County, were analyzed for 51 chemical species. Of these variables, 35 showed detectable variation over the area, and 29 were utilized in a correlation analysis. Two populations are distinguished in the collected samples and are especially evident in the...
Selected climatic characteristics of the southeastern Uinta Basin, Utah and Colorado
S. D. Waltemeyer
1982, Open-File Report 82-91
The southeastern Uinta Basin in Utah and Colorado contains large reserves of oil shale, the mining of which could affect the area 's water resources. Climatic characteristics of the area, which were evaluated as one phase of a comprehensive hydrologic study, are presented to help provide the means of evaluating...
Drainage areas in New Jersey; Delaware River basin and streams tributary to Delaware Bay
A. J. Velnich
1982, Open-File Report 82-572
Drainage areas of New Jersey streams tributary to the Delaware River and Delaware Bay are listed for over 1,100 sites. Tables show the descriptive location of each site, the latitude and longitude, county, and National Topographic map name. For gaged sites established through 1980, the U.S. Geological Survey station name...
Proceedings of the Second Joint Meeting of the U.S.-Japan Conference on Natural Resources (UJNR) Panel on Earthquake Prediction Technology, July 13-17, 1981
David P. Hill, Keiji Nishimura
1982, Open-File Report 82-180
The Second Joint Meeting of the UJNR Panel on Earthquake Prediction Technology was held at the U.S. Geological Survey facilities in Menlo Park, California, during the week of July 13, 1981. This panel, which was established in 1978, is the newest of 17 panels under the United States/Japan Cooperative Program...
Use of a three-dimensional model for the analysis of the ground-water flow system in Parker Valley, Arizona and California
Patrick Tucci
1982, Open-File Report 82-1006
A three-dimensional, finite-difference model was used to simulate ground-water flow conditions in Parker Valley. The study evaluated present knowledge and concepts of the ground-water system and the ability of the model to represent the system. Modeling assumptions and generalized physical parameters that were used may have transfer value in the...
