Fluvial sediment study of Fishtrap and Dewey Lakes drainage basins, Kentucky-Virginia
William F. Curtis, Russell F. Flint, Frederick H. George, John F. Santos
1978, Water-Resources Investigations Report 77-123
Fourteen drainage basins above Fishtrap and Dewey Lakes in the Levisa Fork and Johns Creek drainage basins of eastern Kentucky and southwestern Virginia were studied to determine sedimentation rates and origin of sediment entering the two lakes. The basins ranged in size from 1.68 to 297 square miles. Sediment yields...
Water-resources appraisal of the Wet Mountain Valley, in parts of Custer and Fremont counties, Colorado
C.J. Londquist, R.K. Livingston
1978, Water-Resources Investigations Report 78-1
The Wet Mountain Valley is an intermontane trough filled to a depth of at least 6,700 feet with unconsolidated deposits. Ground water occurs under both artesian and water-table conditions within the basin-fill aquifer and ground-water moverment is toward Grape and Texas Creeks. The depth to the water table is less...
Hydrologic evaluation of part of central Volusia County, Florida
P. W. Bush
1978, Water-Resources Investigations Report 78-89
Municipal wells close to the Atlantic Coast cannot be expected to supply the steadily increasing population of Volusia County, Florida, indefinitely without causing saltwater intrusion problems. Therefore, new wells will be drilled away from the coast. The source of water for the planned artesian aquifer well field will be leakage...
Hydrologic data for Soldier Creek Basin, Kansas
William J. Carswell Jr.
1978, Water-Resources Investigations Report 78-87
Selected hydrologic data collected in the Soldier Creek basin in Kansas are available on magnetic tape in card-image format. Data on the tape include water discharge in fifteen-minute and daily time intervals; rainfall in fifteen-minute and daily time intervals; concentrations and particle sizes of suspended sediment; particle sizes of bed...
Scatter diagrams and correlations of uranium in surface water versus discharge, conductivity, and pH at various locations throughout the United States
Jennie L. Ridgley, Karen J. Wenrich-Verbeek
1978, Open-File Report 78-581
A study of the relationship of stream discharge, conductivity, and pH with uranium concentration in surface waters has been made for various locations in the United States utilizing data collected, for the most part, by the U.S. Geological Survey (USGS). The results of the study are portrayed by the scatter...
Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: January 1978
J.B. Townshend, J.E. Papp, M.J. Moorman, S.P. Tilton
1978, Open-File Report 78-300-A
The preliminary geomagnetic data included here is made available to scientific personnel and organizations, as part of a cooperative effort and on a data exchange basis because of the early need by some users. To avoid delay, all of the data is copied from original forms processed at the observatory;...
Sediment transport in the Feather River, Lake Oroville to Yuba City, California
George Porterfield, Robert D. Busch, Arvi O. Waananen
1978, Water-Resources Investigations Report 78-20
Regulation of the Feather River by Oroville Dam and reservoir in northeast California (beginning in 1967) changed the streamflow and sediment discharge downstream from the dam. Changes in channel geometry to adjust to the new regimen were still in process in 1975. Streamflow and sediment concentration and discharge had decreased....
Unsteady streamflow simulation using a linear implicit finite-difference model
Larry F. Land
1978, Water-Resources Investigations Report 78-59
A computer program for simulating one-dimensional subcritical, gradually varied, unsteady flow in a stream has been developed and documented. Given upstream and downstream boundary conditions and channel geometry data, roughness coefficients, stage, and discharge can be calculated anywhere within the reach as a function of time.The program uses a linear...
Availability and quality of water from shallow aquifers in Duval County, Florida
Lawson V. Causey, G. G. Phelps
1978, Water-Resources Investigations Report 78-92
The shallow-aquifer system in Duval County, Fla., overlies the Florida aquifer and is composed chiefly of sand, clay, sandy clay, and limestone. Thickness of the system ranges from about 300 to 600 feet. The upper 150 feet of deposits, consisting of the water-table and shallow-rock zones, are the most dependable...
Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: February 1978
J.B. Townshend, J.E. Papp, M.J. Moorman, S.P. Tilton
1978, Open-File Report 78-300-B
The preliminary geomagnetic data included here is made available to scientific personnel and organizations, as part of a cooperative effort and on a data exchange basis because of the early need by some users. To avoid delay, all of the data is copied from original forms processed at the observatory;...
Ten-year low mean monthly discharge determinations for ungaged streams near waste-stabilization ponds in Wisconsin
Stephen J. Field
1978, Water-Resources Investigations Report 78-49
Communities that use fill-and-draw waste-water treatment lagoons or waste-stabilization ponds are required to discharge during the spring and fall of the year at a rate that does not exceed the assimilative capacity of the receiving stream. The 10-year low mean monthly discharge (MMQ10) for October, November, April, and May for...
