Reconnaissance evaluation of water resources for hydraulic coal mining, Grand Hogback coal field: Garfield and Rio Blanco Counties, Colorado
William M. Alley, Linda J. Britton, Elaine L. Boyd
1978, Open-File Report 78-885
Surface-water and ground-water data were compiled for the parts of the Colorado River and the White River basins in and adjacent to the Grand Hogback coal field. The data were evaluated to assess the quantity and quality of water resources available in the area for use in hydraulic coal mining....
Reconnaissance evaluation of water resources for hydraulic coal mining, Crested Butte coal field, Gunnison County, Colorado
William M. Alley, Linda J. Britton, Elaine L. Boyd
1978, Open-File Report 78-938
Available surface-water and ground-water data were compiled for the parts of the Gunnison River basin in and adjacent to the Crested Butte coal field. The data were evaluated to assess the quantity and quality of water resources in the area for use in hydraulic coal mining.Based on discharge records, surface-water...
Five-day recorder seismic system
Ed Criley, Jerry P. Eaton, Jim Ellis
1978, Open-File Report 78-266
The 10-day recorder seismic system used by the USGS since 1965 has been modified substantially to improve its dynamic range and frequency response, to decrease its power consumption and physical complexity, and to make its recordings more compatible with other NCER systems to facilitate data processing. The principal changes include:...
Analyses of water, core material, and elutriate samples collected near Yazoo City, Mississippi (Yazoo Headwater Project)
Harold L. Leone, Alton J. Dupuy
1978, Open-File Report 78-792
Five core-material-sampling sites were chosen by the U.S. Army Corps of Engineers to represent areas of proposed dredging activity. Four receiving-water sites also were selected to represent the water that will contact the proposed dredged material. Chemical and physical analyses were performed upon core material and native-water samples from these...
Bibliographic supplement to U.S. Geological Survey Bulletin 1426 for 1975 through June 1977
Wenonah E. Bergquist
1978, Open-File Report 78-349
This bibliography is a supplement to U.S. Geological Survey Bulletins 1426 (Bergquist, 1976) and 1263 (Heath and Tabacchi, 1968). The titles listed result from work undertaken in cooperation with national agencies partly through technical assistance projects under the auspices of the Agency for International Development, U.S. Department of State; partly...
Cross-section data for selected Puerto Rico streams
Eloy Colon-Dieppa, Ralph Gonzalez
1978, Open-File Report 78-882
The data presented in this report were originally collected for the purpose of delineating the inundation which could be expected by floods of selected magnitudes. As this study progressed, it became apparent that further analysis would be a duplication of effort as the United States Flood Insurance Administration was requiring...
Bottom currents and bottom sediment distribution in Massachusetts Bay
Bradford Butman, John Stevens Schlee, Charles J. O’Hara, Robert H. Meade
1978, Open-File Report 78-369
Massachusetts Bay is a coastal Bay 100 km long and 40 km wide located in the western Gulf of Maine. The Bay is open only to the Gulf to the east; the opening is partially blocked by a shallow bank. The bottom sediment distribution in the bay is complex; fine...
Selected hydrologic data, 1931-77, Wasatch Plateau-Book Cliffs coal-fields area, Utah
K.M. Waddell, H.L. Vickers, Robbin T. Upton, P. Kay Contratto
1978, Open-File Report 78-121
The Wasatch Plateau-Book Cliffs coal-fields area in east-central Utah includes a significant part of the State's coal resources and is currently (1977) the most active coal-mining area in the State.This report presents data gathered by the U.S. Geological Survey as part of a hydrologic reconnaissance carried out during the period...
Development of a technique for the rapid estimation of earthquake losses
Sylvester Theodore Algermissen, M.B. McGrath, S.L. Hanson
1978, Open-File Report 78-440
A simple, general technique has been outlined for the rapid, approximate estimation of building losses resulting from ground shaking during earthquakes. The technique has been applied to the San Francisco Bay area. Ground shaking, ground failures of various kinds, surface faulting, tsunamis, and earthquake induced fires are all responsible for...
Metropolitan land cover inventory using multiseasonal Landsat data
William J. Todd, R.N. Hill, C.C. Henry, B.L. Lake
1978, Open-File Report 78-378
As a part of the Pacific Northwest Land Resources Inventory Demonstration Project (PNLRIDP), planners from State, regional, and local agencies in Oregon are working with scientists from the EROS Data Center (USGS), Ames Research Center (NASA), and the Jet Propulsion Laboratory (California Institute of Technology) to obtain practical training and...
