Regional Aquifer-System Analysis Program of the US Geological Survey; bibliography, 1978-86
J.B. Weeks, Ren Jen Sun
1987, Water-Resources Investigations Report 87-4138
The Regional Aquifer-System Analysis Program of the U.S. Geological Survey was initiated in 1978. The purpose of this program is to define the regional geohydrology and establish a framework of background information on geology, hydrology, and geochemistry of the Nation 's important aquifer systems. This information is needed to develop...

1987, Open-File Report 87-212
Information on the geology, geomorphology, soils, climate, hydrology, water use, land use, population, and coal mining history of Clay, Owen, Sullivan, and Vigo Counties in Indiana is summarized. Site-specific information is given on the morphology , geology, soils, land use, coal mining history, and hydrologic instrumentation of the six watersheds...

1987, Professional Paper 1431
The relation of hydrologic setting and temporal variability in hydrology to nutrient content and geochemical characteristics of a group of prairie wetlands and adjacent ground water was studied during the period 1979-82. Although data were collected from many wetlands and wells at the study site, emphasis in this report primarily...
Hydrologic data for urban studies in the Austin metropolitan area, Texas, 1985
J.D. Gordon, D.L. Pate, M.E. Dorsey
1987, Open-File Report 87-224
Hydrologic investigations of urban watersheds in Texas were begun by the U.S. Geological Survey in 1954. Studies are now in progress in Austin, and Houston. Studies have been completed in the Dallas, Fort Worth, and San Antonio areas. The Geological Survey, in cooperation with the Texas Department of Water Reources, began...
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...
Hydrogeology of McMullen Valley, west-central Arizona
D. R. Pool
1987, Water-Resources Investigations Report 87-4140
The geohydrology of McMullen Valley, west-central Arizona, was investigated using geologic, geophysical, and hydrologic data and a numerical model of the groundwater system. Interpretation of geologic and geophysical information indicates that the main structure of McMullen Valley is a syncline that has been normal faulted on the southeast side. Basin...
Method for estimating the magnitude and frequency of floods at ungaged sites on unregulated rural streams in Iowa
O. G. Lara
1987, Water-Resources Investigations Report 87-4132
This report provides techniques and procedures for estimating the probable magnitude and frequency of floods at ungaged sites on Iowa streams. Physiographic characteristics were used to define the boundaries of five hydrologic regions. Regional regression equations that relate the size of the drainage area to flood magnitude are defined for...
Annual yield and selected hydrologic data for the Arkansas River Basin Compact, Arkansas-Oklahoma, 1986 water year
M. A. Moore, T.E. Lamb, S. P. Blumer
1987, Open-File Report 87-203
The computed annual yield and deficiency of the subbasins as defined in the Arkansas River Compact, Arkansas-Oklahoma, are given in tables. Actual runoff from the subbasins and depletion caused by major reservoirs in the compact area are also given in tabular form. Monthly, maximum, minimum, and mean discharges are shown...
Quality of ground water in Idaho
Johnson J. Yee, William R. Souza
1987, Water Supply Paper 2272
The major aquifers in Idaho are categorized under two rock types, sedimentary and volcanic, and are grouped into six hydrologic basins. Areas with adequate, minimally adequate, or deficient data available for groundwater-quality evaluations are described. Wide variations in chemical concentrations in the water occur within individual aquifers, as well as...
Operation of hydrologic data collection stations by the U.S. Geological Survey in 1987
Alberto Condes de la Torre
1987, Open-File Report 87-563
The U.S. Geological Survey operates hydrologic data collection stations nationwide which serve the needs of all levels of government, the private sector, and the general public, for water resources information. During fiscal year 1987, surface water discharge was determined at 10,624 stations; stage data on streams, reservoirs, and lakes were...
Hydrologic hazards along Squaw Creek from a hypothetical failure of the glacial moraine impounding Carver Lake near Sisters, Oregon
Antonius Laenen, K. M. Scott, J. E. Costa, L.L. Orzol
1987, Open-File Report 87-41
A hydrologic hazard exists that could create a large-magnitude, but short-duration, flood in the Squaw Creek drainage and inundate areas in and around the community of Sisters, Oregon. There is a 1 to 5% probability that Carver Lake, located at elevation 7,800 ft above sea level on the east slope...
Effects on water quality due to flood-water detention by Barker and Addicks Reservoirs, Houston, Texas
Fred Liscum, R.L. Goss, E.M. Paul
1987, Water-Resources Investigations Report 86-4356
The Barker and Addicks Reservoirs, located about 16 miles west of Houston, Texas, provide flood-detention storage for storm runoff. Of interest are the water-quality characteristics in the study area and changes in water quality during detention. Study area sampling sites were selected upstream along Buffalo Bayou for Barker Reservoir and...

Hydrologic and geologic factors affecting land subsidence near Eloy, Arizona
V.J. Epstein
1987, Water-Resources Investigations Report 87-4143
At an extensometer site near Eloy, Arizona, 1.09 m of land subsidence caused by groundwater withdrawal were measured by leveling in 1965-83. The extensometer, which partially penetrates the compressible sediments, recorded 0.82 m of compaction during the same period. By use of a one-dimensional model, cumulative daily compaction values were...
