Comparison of estimates of evapotranspiration and consumptive use in Palo Verde Valley, California
Lee H. Raymond, Sandra J. Owen-Joyce
1987, Water-Resources Investigations Report 87-4071
Estimates of evapotranspiration and consumptive use by vegetation in Palo Verde Valley, California, were compared for calendar years 1981 to 1984. Vegetation types were classified, and the areas covered by each type were computed from Landsat satellite digital-image analysis. Evapotranspiration was calculated by multiplying the area of each vegetation type...
Surface-water quality in Pequea Creek basin, Pennsylvania, 1977-79
J. R. Ward
1987, Water-Resources Investigations Report 85-4250
A study of the Pequea Creek basin was conducted by the U.S. Geological Survey, in cooperation with the Susquehanna River Basin Commission and the EPA from February 1977 through March 1979. Pequea Creek drains an intensive agricultural area of 154 sq mi in southeastern Pennsylvania, and enters the Susquehanna River...
The principle of superposition and its application in ground-water hydraulics
Thomas E. Reilly, O. Lehn Franke, Gordon D. Bennett
1987, Techniques of Water-Resources Investigations 03-B6
The principle of superposition, a powerful mathematical technique for analyzing certain types of complex problems in many areas of science and technology, has important applications in ground-water hydraulics and modeling of ground-water systems. The principle of superposition states that problem solutions can be added together to obtain composite solutions. This...
Traveltime and dispersion in the New River, Hinton to Gauley Bridge, West Virginia
David H. Appel, S. B. Moles
1987, Water-Resources Investigations Report 87-4012
Traveltime and dispersion studies were conducted on a 65-mile-long reach of the New River between Hinton and Gauley Bridge, West Virginia. Four sets of measurements were made from August 1985 to May 1986 at river discharges of about 2,220, 3 ,200, 9,200, and 18,000 cu ft/sec, which correspond to flow...
Summary mineral resource appraisal of the Richfield 1° x 2° quadrangle, west-central Utah
Thomas August Steven, Hal T. Morris
1987, Circular 916
The mineral resource potential of the Richfield 1° x 2° quadrangle, Utah, has been appraised using geological, geophysical, geochemical, and remote-sensing techniques. These studies have led to many publications giving basic data and interpretations; of these, a series of 18 maps at 1:250,000 and 1:500,000 scales summarizing aspects of the...
Surface-water hydrology of the Little Black River basin, Missouri and Arkansas, before water-land improvement practices
W.R. Berkas, Suzanne R. Femmer, T. O. Mesko, B. W. Thompson
1987, Water-Resources Investigations Report 87-4076
The U. S. Department of Agriculture, Soil Conservation Service, in accordance with Public Law 566, is implementing various types of water-land improvement practices in the Little Black River basin in southeastern Missouri. These practices are designed, in part, to decrease the suspended sediment (SS) transport in the basin, decrease flood...
Ground-water and soil contamination near two pesticide-burial sites in Minnesota
J. R. Stark, J.D. Strudell, P.A. Bloomgren, P. Eger
1987, Water-Resources Investigations Report 87-4115
Preliminary investigations of the geology, groundwater hydrology , and soil and groundwater chemistry at sites in Pine and St. Louis Counties, Minnesota, have shown that contamination associated with pesticides buried at the sites is not widespread or highly concentrated. None of the pesticides sampled for in soil and in groundwater...
Regional study of the Castle Hayne Aquifer of eastern North Carolina
W.L. Lyke, R. W. Coble
1987, Open-File Report 87-571
The Castle Hayne aquifer is an eastward sloping and thickening wedge of limestone and sandstone, located in a 12,500 sq mi area in the eastern part of North Carolina. The Castle Hayne aquifer is the major source of freshwater for much of coastal North Carolina where the aquifers underlying the...
Data on ground-water quality for the McDermitt 1° x 2° quadrangle, northern Nevada
Alan H. Welch, Rhea P. Williams
1987, Open-File Report 85-648-E
Water quality data for groundwater were compiled for the McDermitt 1° x 2° quadrangle which covers a portion of northern Nevada. Chemical characteristics of the water are shown on a map (at a scale of 1:250,000) and on trilinear diagrams for the major ions. The data for the area are...
Data on ground-water quality for the Lovelock 1° x 2° quadrangle, western Nevada
Alan H. Welch, Rhea P. Williams
1987, Open-File Report 85-648-F
Water quality data for groundwater has been compiled for the Lovelock 1 degree x 2 degree quadrangle which covers a portion of western Nevada. Chemical characteristics of the water are shown on a map (at a scale of 1:250,000) and on trilinear diagrams for the major ions. The data for...
Seismicity map of the state of Tennessee
B.G. Reagor, C. W. Stover, S. T. Algermissen
