Spokane Valley-Rathdrum Prairie aquifer, Washington and Idaho
B. W. Drost, Harold R. Seitz
1977, Open-File Report 77-829
The Spokane Valley-Rathdrum Prairie aquifer is composed of unconsolidated Quaternary glaciofluvial deposits underlying an area of about 350 square miles. Transmissivities in the aquifer range from about 0.13 million to 11 million feet squared per day and ground-water velocities exceed 60 feet per day in some areas. The water-table gradient...
Mineral resources of the Tracy Arm-Fords Terror Wilderness Study Area and vicinity, Alaska
David A. Brew, Donald Grybeck, Bruce R. Johnson, Robert C. Jachens, C.J. Nutt, D.F. Barnes, A.L. Kimball, J.C. Still, J.L. Rataj
1977, Open-File Report 77-649
The Wilderness Study Area consists of about 322,300 hectares (1,250 square miles or 796,400 acres) on the southwest side of the Coast Range in southeastern Alaska about 72 km (45 miles) southeast of Juneau, Alaska (fig. 1). An additional 142,800 hectares (550 square miles or 352,900 acres) lying in part...
Comprehensive monitoring of meteorology, hydraulics, and thermal regime of the San Diego Aqueduct, California
Harvey E. Jobson, Alex M. Sturrock
1976, Open-File Report 76-628
Water temperature, as well as meteorologic and hydraulic variables which influence the energy budget of the San Diego Aqueduct in southern California, were continuously monitored for a 1-year period beginning July 24, 1973. Incoming solar and atmospheric radiation, windspeed and direction, water temperature, and wet- and dry-bulb air temperatures were...
Hard rock uranium potential in Alaska
Thomas P. Miller
1976, Open-File Report 76-246
Discussing the potential of "hardrock" (i.e., non-sedimentary type) uranium deposits in a 586,000 mi2 portion of the North America Cordillera is a difficult task compounded by the fact that the remoteness of much of the region and the logistical difficulties have resulted in only reconnaissance geologic information being available for...
Geological Survey and selected U.S. Bureau of Mines and Alaska Division of Geological and Geophysical Surveys reports and maps on Alaska released during 1975, indexed by quadrangle
Edward Huntington Cobb
1976, Open-File Report 76-332
All Geological Survey reports and maps on Alaska published or released to open files during 1975 are listed by the quadrangles (scale 1:250,000) into which Alaska has been divided for topographic mapping (p. 3). Also listed are U.S. Bureau of Mines reports on the geology and mineral resources of Alaska,...
Laboratory hydraulic calibration of the Helley-Smith bedload sediment sampler
Leroy Druffel, W. W. Emmett, V.R. Schneider, J. V. Skinner
1976, Open-File Report 76-752
The Helley-Smith bedload sampler operates on a pressure-difference principle and consists of an expanding nozzle, nylon-mesh sample bag , and external components for structural integrity and stability under flow conditions. The Helley-Smith bedload sampler has a hydraulic efficiency, the ratio of the mean velocity in the sampler nozzle to the...
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...
