Planning and design of studies for river-quality assessment in the Truckee and Carson River basins, California and Nevada
Jon O. Nowlin, W. M. Brown, L. H. Smith, R.J. Hoffman
1980, Open-File Report 80-435
The objectives of the Geological Survey 's river-quality assessment in the Truckee and Carson River basins in California and Nevada are to identify the significant resource management problems; to develop techniques to assess the problems; and to effectively communicate results to responsible managers. Six major elements of the assessment to...
An annotated bibliography of devices developed for direct measurement of seepage
Mark R. Carr, Thomas C. Winter
1980, Open-File Report 80-344
The need for information on the interrelationship of groundwater and surface water is causing a growing interest in methods used for direct measurement of seepage to and from surface-water bodies. Instruments developed for measurement of seepage date from about the mid 1940 's largely in response to the need for...
Ground-water conditions at Beale Air Force Base and vicinity, California
R. W. Page
1980, Open-File Report 80-204
Ground-water conditions were studied in a 168-square-mile area between the Sierra Nevada and the Feather River in Yuba County, Calif. The area is in the eastern part of the Sacramento Valley and includes most of Beale Air Force Base. Source, occurrence, movement, and chemical quality of the ground water were...
Summaries of data on and lists of references to metallic and selected nonmetallic mineral deposits in the Blying Sound and Seward quadrangles, Alaska
1980, Open-File Report 80-621
These summaries of data on metallic and selected nonmetallic mineral occurrences and lists of selected references to them in Geological Survey, U.S. Bureau of Mines, and State of Alaska Division of Geological and Geophysical Surveys (and predecessor State and Territorial agencies) reports and maps and a very few journal articles...
Analyses of water, core material, and elutriate samples collected near Sicily Island, Louisiana (Sicily Island area levee project)
Dennis K. Demcheck, Alton J. Dupuy
1980, Open-File Report 80-434
Samples consisting of composited core material were collected from five areas by the U.S. Army Corps of Engineers and analyzed by the U.S. Geological Survey to provide data on the impact of proposed channel excavation and levee construction in the Sicily Island area, Louisiana. Samples of receiving water from the...
Directory of member organizations of the National Water Data Exchange (NAWDEX)
Janet M. Nokes, Cassandra D. Blackwell
1980, Open-File Report 80-556
The National Water Data Exchange (NAWDEX) is a national confederation of water-oriented organizations working together to improve access to water data. It consists of member organizations from all sectors of the water-data community. This Directory provides the names, addresses, and telephone numbers of all NAWDEX member organizations and their designated...
Evaluation of water resources in the Reedsport area, Oregon
Joseph F. Rinella, F. J. Frank, A.R. Leonard
1980, Open-File Report 80-444
The water supply for the Reedsport area is obtained from Clear Lake, a 310-acre coastal lake that contains 16, 600 acre-feet of water at full-pool. The lake receives about 6,000 acre-feet of water annually from runoff and direct precipitation, and it loses about 600 acre-feet by evaporation. The 2,100 acre-feet...
Flood-prone area maps of three sites along the Trans-Alaska Pipeline, Alaska
Robert D. Lamke, Stanley H. Jones
1980, Open-File Report 80-209
The Bureau of Land Management requested on May 3, 1979 that the U.S. Geological Survey determine the base (100-year) flood-plain limits at three sites (fig. 1) along the Trans-Alaska Pipeline System Highway (Haul Road) between the Yukon River and Prudhoe Bay in order to issue land-use permits. The Alaska Department...
Hydrogeologic data for selected coal areas, east-central Montana
Robert S. Roberts
1980, Open-File Report 80-329
Hydrogeologic data were collected in selected coal areas of east-central Montana to provide a basis for evaluating the effects of future coal development on the groundwater resources. Inventory records for 916 domestic, stock, public supply, commercial, and test wells are tabulated in the report; the data were collected principally from...
A practical Lagrangian transport model
Harvey E. Jobson
1980, Open-File Report 80-206
An unconditionally stable and practical transport model for use in upland streams and rivers has been developed and verified. Basing the model on the Lagrangian, rather than the Eulerian, reference frame greatly reduces the numerical problems associated with solving the advective terms of the convective-diffusion equation. The model contains almost...
