Water resources of the Toppenish Creek Basin, Yakima Indian Reservation, Washington
Water Resources Division, U.S. Geological Survey
1975, Water-Resources Investigations Report 74-42
The Yakima River, which flows along the eastern margin of the Yakima Indian Reservation, provides about 93 percent of the irrigation water for the eastern part of the Toppenish Creek basin--the major agricultural area in the basin . During 1972, the total surface water diverted from all streams and from...
An introduction to the processes, problems, and management of urban lakes
L. J. Britton, R. C. Averett, R. F. Ferreira
1975, Circular 601-K
Lakes are bodies of water formed in depressions on the earth's surface, and as such, act as depositories for a variety of chemical and biological materials. The study of lakes has become increasingly prevalent in recent years. Lakes are a valuable resource, and their multiple uses have made them susceptible...
Sediment transport, turbidity, channel configuration, and possible effects of impoundment of the Mad River, Humboldt County, California
William M. Brown III
1975, Water-Resources Investigations Report 75-26
Sediment-transport conditions were determined at two stations, Mad River near Arcata and Mad River near Kneeland. Using a release-flow model and an empirical equation, the suspended-sediment discharge at Kneeland was estimated to be about 60 percent of the suspended-sediment discharge at the Arcata station. The study of the proposed impoundment...
The potentiometric surface and water quality of the Floridan aquifer; in southwest Hillsborough County, Florida, 1952-74
A. Dan Duerr
1975, Water-Resources Investigations Report 75-50
Large ground-water withdrawals and a 10-year period of below-normal rainfall have caused the potentiometric surface of the Floridan aquifer to decline more than 10 feet (3 metres) in most of a 200-square-mile (520-square-kilometre) area of southwest Hillsborough County (fig. 1). The lowered ground-water levels and the consequent threat of salt-water...
Analysis of operational plan for Lake Chippewa near Winter, Wisconsin
William R. Krug
1975, Open-File Report 75-487
Historical inflows into Lake Chippewa for 39 years of record were analyzed to determine the possibility of operating the flowage within a 2-foot (0.6-metre) range of stage while maintaining a minimum discharge of 57 cubic feet per second (1.6 cubic metres per second) and limiting the maximum discharge to 7,000...
Stochastic analysis of particle movement over a dune bed
Baum K. Lee, Harvey E. Jobson
1975, Open-File Report 75-358
Stochastic models are available that can be used to predict the transport and dispersion of bed-material sediment particles in an alluvial channel. These models are based on the proposition that the movement of a single bed-material sediment particle consists of a series of steps of random length separated by rest...
Sandstone geometry, porosity and permeability distribution, and fluid migration in eolian system reservoirs
Robert Lupe, Thomas S. Ahlbrandt
1975, Open-File Report 75-357
Upper Paleozoic to Mesozoic eolian blanket sandstones of the Colorado Plateau and the Rocky Mountains of Colorado and southern Wyoming are texturally complex. As petroleum reservoirs they commonly have poor performance histories. They contain the sediments of a depositional system comprised of three closely associated depositional subenvironments: dune, interdune, and...
Antimony deposits of Quetta-Pishin District, Quetta Division, Pakistan
F.L. Klinger, John J. Matzko, S.H. Abbas
1975, Open-File Report 75-161
Vein-type deposits of antimony ore, consisting of stibnite and quartz, are found in the hanging wall of faults cutting slate of probable Miocene age 15 miles northeast of Qila Abdullah in the Quetta-Pishin District. The ore is associated with zones of oxidized slate. Although the known deposits are small, the...
