Water resources of Sedgwick County, Kansas
H.E. Bevans
1989, Water-Resources Investigations Report 88-4225
Hydrologic data from streams, impoundments, and wells are interpreted to: (1) document water resources characteristics; (2) describe causes and extent of changes in water resources characteristics; and (3) evaluate water resources as sources of supply. During 1985, about 134,200 acre-ft of water (84% groundwater) were used for public (42%), irrigation,...
Stratigraphy of the unsaturated zone at the radioactive waste management complex, Idaho National Engineering Laboratory, Idaho
S. R. Anderson, B. D. Lewis
1989, Water-Resources Investigations Report 89-4065
A complex sequence of layered basalt flows, cinders, and sediment underlies the Radioactive Waste Management Complex at the Idaho National Engineering Laboratory in southeastern Idaho. Wells drilled to 700 ft penetrate a sequence of 10 basalt-flow groups and 7 major sedimentary interbeds that range in age from about 100,000 to...
Use of temperature profiles beneath streams to determine rates of vertical ground-water flow and vertical hydraulic conductivity
Wayne W. Lapham
1989, Water Supply Paper 2337
The use of temperature profiles beneath streams to determine rates of vertical ground-water flow and effective vertical hydraulic conductivity of sediments was evaluated at three field sites by use of a model that numerically solves the partial differential equation governing simultaneous vertical flow of fluid and heat in the Earth....
Sedimentation of Lake Taneycomo, Missouri, 1913-1987
W.R. Berkas
1989, Water-Resources Investigations Report 89-4160
On the basis of the data from a sedimentation survey done by the U.S. Department of Agriculture, Soil Conservation Service, during 1935 and data collected by the U.S. Geological Survey during 1987, the volume of sediment accumulated in Lake Taneycomo from 1913 to 1935 and 1913 to 1987 was determined....
Evaluation of field sampling and preservation methods for strontium-90 in ground water at the Idaho National Engineering Laboratory, Idaho
L.D. Cecil, L.L. Knobel, S.J. Wegner, L.L. Moore
1989, Water-Resources Investigations Report 89-4146
Water from four wells completed in the Snake River Plain aquifer was sampled as part of the U.S. Geological Survey 's quality assurance program to evaluate the effect of filtration and preservation methods on strontium-90 concentrations in groundwater at the Idaho National Engineering Laboratory. Water from each well was filtered...
Proceedings of the Advanced Seminar on one-dimensional, open-channel Flow and transport modeling
1989, Water-Resources Investigations Report 89-4061
In view of the increased use of mathematical/numerical simulation models, of the diversity of both model investigations and informational project objectives, and of the technical demands of complex model applications by U.S. Geological Survey personnel, an advanced seminar on one-dimensional open-channel flow and transport modeling was organized and held on...
Estimation of flood-frequency characteristics and the effects of urbanization for streams in the Philadelphia, Pennsylvania area
J.F. Bailey, W.O. Thomas Jr., K. L. Wetzel, T.J. Ross
1989, Water-Resources Investigations Report 87-4194
This report provides a method for estimating the magnitude and frequency of floods for small streams in the Philadelphia, Pennsylvania area. Data collected at 21 streamflow gaging stations were used in a multiple-regression analysis to develop equations for computation of peak-flow characteristics. The flood equations were determined by relating flood-frequency...
Sedimentary structures and textures of Rio Orinoco channel sands, Venezuela and Colombia
Edwin Dinwiddie McKee
1989, Water Supply Paper 2326-B
Most sedimentary structures represented in sand bodies of the Rio Orinoco are tabular-planar cross-strata which, together with some wedge-planar cross-strata, are the products of sand-wave deposition. Locally, in areas of river meander where point bars characteristically form, trough structures forming festoon patterns are numerous. At a few localities, sets of...
Evapotranspiration estimates using remote-sensing data, Parker and Palo Verde valleys, Arizona and California
Lee H. Raymond, Kelly V. Rezin
1989, Water Supply Paper 2334
In 1981 the U.S. Geological Survey established an experimental project to assess the possible and practical use of remote-sensing data to estimate evapotranspiration as an approximation of consumptive use of water in the lower Colorado River flood plain. The project area was in Parker Valley, Arizona. The approach selected was...
Water resources data for Mississippi, water year 1988
E.J. Tharpe, M.L. Plunkett, F. Morris, W. T. Oakley
1989, Water Data Report MS-88-1
Water resources data for the 1988 water year for Mississippi consist of records of stage, discharge, and water quality of streams; stage, and water quality of lakes and reservoirs; and water levels and water quality of ground-water wells. This report contains records of water discharge at 70 gaging stations; stage...
International strategic minerals inventory summary report; natural graphite
U.H. Krauss, H.W. Schmidt, H.A. Taylor Jr., D. M. Sutphin
1989, Circular 930-H
Natural graphite is a crystalline mineral of pure carbon which normally occurs in the form of platelet-shaped crystals. It has important properties, such as chemical inertness, low thermal expansion, and lubricity, that make it almost irreplaceable for certain uses such as refractories and steelmaking. Graphite ore types are crystalline (flake...
Sand waves, bars, and wind-blown sands of the Rio Orinoco, Venezuela and Colombia
Carl F. Nordin, David Perez-Hernandez
1989, Water Supply Paper 2326-A
During March 1982, a reconnaissance study was carried out along a reach of the Rio Orinoco between Puerto Ayacucho and Ciudad Bolivar. This was the low-flow season. Samples of bed material and suspended sediments were collected, sonic records of the bed were obtained at several locations, and the exposed bars...
Isotopic evidence for evolution of sub-continental mantle during Red Sea rifting
John S. Pallister, Ernst Hegner
1989, Open-File Report 89-335
Tertiary igneous rocks from near Al Lith, Saudi Arabia are alkaline to subalkaline and bimodal in composition, and document early and late rift volcanism (≥30 Ma to ~20 Ma, 11 Ma and 3 Ma) in the central part of the Red Sea rift. Isotopic and trace-element data from twenty-five samples...
