Iowa ground-water quality
R.C. Buchmiller, P. J. Squillace, R.D. Drustrup
1987, Open-File Report 87-725
The population served by ground-water supplies in Iowa (fig. L4) is estimated to be about 2,392,000, or 82 percent of the total population (U.S. Geological Survey, 1985, p. 211). The population of Iowa is distributed fairly uniformly throughout the State (fig. IB), with 59 percent residing in rural areas or...
Computation of rapidly varied unsteady, free-surface flow
D.R. Basco
1987, Water-Resources Investigations Report 83-4284
Many unsteady flows in hydraulics occur with relatively large gradients in free surface profiles. The assumption of hydrostatic pressure distribution with depth is no longer valid. These are rapidly-varied unsteady flows (RVF) of classical hydraulics and also encompass short wave propagation of coastal hydraulics. The purpose of this report is...
Water resources data, Texas, water year 1986. Volume 2: San Jacinto River basin, Brazos River basin, San Bernard River basin, and intervening coastal basins
H.D. Buckner, E.R. Carillo, H.J. Davidson
1987, Water Data Report TX-86-2
The Water Resources Division of the U.S. Geological Survey, in cooperation with Federal, State, and City agencies, obtains a large amount of data pertaining to the water resources of Texas each water year. Such data, accumulated during many water years, constitute a valuable data base for developing an improved understanding...
Ground-water quality assessment of the central Oklahoma Aquifer, Oklahoma; project description
S. C. Christenson, D.L. Parkhurst
1987, Open-File Report 87-235
In April 1986, the U.S. Geological Survey began a pilot program to assess the quality of the Nation's surface-water and ground-water resources. The program, known as the National Water-Quality Assessment (NAWQA) program, is designed to acquire and interpret information about a variety of water-quality issues. The Central Oklahoma aquifer project is...
Water quality of the Malheur Lake system and Malheur River, and simulated water-quality effects of routing Malheur Lake water into Malheur River, Oregon, 1984-85
L. A. Fuste, S. W. McKenzie
1987, Water-Resources Investigations Report 86-4202
Above average precipitation and runoff between 1980 and 1985 have raised the water-surface elevation of Harney, Mud, and Malheur Lakes in eastern Oregon to the highest levels recorded and have caused mixing and interflow of water among the three lakes. A 50% increase in specific conductance throughout Malheur Lake from...
Rainfall-runoff data for Somerset County, New Jersey
J. B. Campbell
1987, Open-File Report 87-384
Rainfall-runoff data are presented for eight selected drainage basins in Somerset County, New Jersey, for the 1980 through 1984 water yr. In order to improve the existing methods for estimating flood-frequency and magnitude throughout the county, in their flood-monitoring efforts by providing real-time data, rainfall-runoff data were collected and a...
The geologic history of the Moon
Don E. Wilhelms, John F. McCauley, Newell J. Trask
1987, Professional Paper 1348
More than two decades of study have established the major features of lunar geologic style and history. The most numerous and significant landforms belong to a size-morphology series of simple craters, complex craters, and ringed basins that were formed by impacts. Each crater and basin is the source of primary...
