Large-scale bedforms in the Platte River downstream from Grand Island, Nebraska; structure, process, and relationship to channel narrowing
K.D. Crowley
1981, Open-File Report 81-1059
The Platte River channel in Nebraska, especially downstream from Grand Island, is characterized by large, periodic, and geometrically distinct bedforms called macroforms. Macroforms have dimensions commensurate with the width and depth of the channel and are emergent at all but the highest flow stages. The encroachment of vegetation on macroforms...
Simulated hydrologic effects of possible ground-water and surface-water management alternatives in and near the Platte River, south-central Nebraska
Alan W. Burns
1981, Open-File Report 81-1116
Digital computer models were developed and used to simulate the hydrologic effects of hypothetical water-management alternatives on the wetland habitat area near Grand Island, Nebr. Areally distributed recharge to and discharge from the aquifer system adjacent to the Platte River between Overton and Grand Island were computed for four hypothetical...
Surface-water and climatological data, Salt Lake County, Utah, water year 1980
G. E. Pyper, R.C. Christensen, D. W. Stephens, H.F. McCormack, L.S. Conroy
1981, Open-File Report 81-1111
This report presents streamflow, water-quality, precipitation, and storm-runoff data collected in Salt Lake County, Utah, during the 1980 water year and certain water-quality data for the 1979 water year which were included for comparative purposes. Surface-water data consist of daily mean values of flow at 33 sites on natural streams,...
Water quality in the tidal Potomac River and estuary, hydrologic data report, 1979 water year
Stephen F. Blanchard, D. C. Hahl
1981, Open-File Report 81-1074
This report contains data on the physical and chemical properties measured during the 1979 water year for the tidal Potomac River and estuary. Data were collected routinely at five major stations and periodically at 14 intervening stations. Each major station represents a cross section through which the transport of selected...
Wildlife survey: Cache Creek and Little Granite Creek, Bridger-Teton National Forest
Franz J. Camenzind
1981, Open-File Report 81-851
The results of the wildlife survey are drawn from 410 hours of field observations by the senior wildlife biologist and two biologist technicians, Terry Peterson and John Hoak. Additional observations were made by other project personnel, coincidental with other assigned duties, and by the senior biologist earlier in the season....
Summary report on the regional geology, environmental considerations for development, petroleum potential, and estimates of undiscovered recoverable oil and gas resources of the United States southeastern Atlantic continental margin in the area of proposed oil and gas lease sale No. 78
William P. Dillon
1981, Open-File Report 81-749
This report summarizes our general knowledge of the geology and petroleum potential, as well as potential problems and hazards associated with development of petroleum resources, of the area proposed for nominations for lease sale number 78. This area includes the U.S. eastern continental margin from the mouth of Chesapeake Bay...
A socioeconomic assessment of the Cache Creek drilling site, Wyoming
Wyoming Research Corp.
1981, Open-File Report 81-862
This report analyzes the potential socioeconomic impacts of drilling two exploratory wells in the immediate vicinity of Jackson, Wyoming in Cache Creek Canyon and Little Granite Creek Canyon.The following conclusions are derived from a review of population projections, an analysis of secondary socioeconomic information, informal interviews of local residents, and...
Submarine topography and physiography of lower Cook Inlet, Alaska
Arnold H. Bouma
1981, Open-File Report 81-1335
The submarine topography of lower Cook Inlet, Alaska, is complex because the bathymetric aspects and water depths change rapidly over short distances. The folded upper Tertiary subbottom was eroded during the first of five major Quaternary glacial advances over the inlet, and later fluvial, fluvioglacial, glacial, and marine erosional and...
Tabulation of the ostracode assemblages and associated organisms from selected bottom grab samples taken in the northeast Gulf of Alaska, F.R.S. Townsend Cromwell Cruise IGAL-75-KC, 1975
Elisabeth M. Brouwers
1981, Open-File Report 81-1314
The U.S. Geological Survey is conducting studies of the Alaskan continental shelf, identifying areas and processes of geological hazard that may affect resource development offshore. These hazards include areas of rapid accumulation of unconsolidated sediment, areas of intense erosional activity, and regions of submarine sliding and slumping; shallow faults are...
Hydrogeologic data from test drilling near Verna, Florida, 1978
Michael Barker, Geronia Bowman, Horace Sutcliffe
1981, Open-File Report 81-634
Four test wells were drilled in the vicinity of the city of Sarasota well field near Verna, Fla., to provide hydrologic and geologic information. An expedient and economical method of air lifting water samples from isolated water-producing zones while drilling was utilized. Lithologic logs of drill cuttings and geophysical logs,...
