Description of the physical environment and coal-mining history of west-central Indiana, with emphasis on six small watersheds
Jeffrey D. Martin, Charles G. Crawford, R.F. Duwelius, D.E. Renn
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...
Density and magnetic susceptibility measurements near the Guadalupe igneous complex, west-central foothills, Sierra Nevada, California
L. M. Hauke, D. A. Ponce, S. R Paterson, O. T. Tobisch
1987, Open-File Report 88-30
Density and magnetic susceptibility measurements of about 380 metasedimentary, metavolcanic, and igneous rocks from an area of the west-central Sierra Nevada foothills were determined. Density measurements were made using the buoyancy method, and magnetic susceptibility measurements were made using a portable magnetic susceptibility meter....
Water resources activities, Georgia District, 1986
Carolyn A. Casteel, Mary D. Ballew
1987, Open-File Report 87-381
The U.S. Geological Survey, through its Water Resources Division , investigates the occurrence, quantity, quality, distribution, and movement of the surface and underground water that composes the Nation 's water resources. Much of the work is a cooperative effort in which planning and financial support are shared by state and...
Geochemistry and preliminary assessment of resource potential for postorogenic granites of the southwestern Arabian Shield, Kingdom of Saudi Arabia
J. S. Stuckless, George VanTrump Jr., C. A. Bush, R. B. Vaughn, A.J. Bartel
1987, Open-File Report 87-509
Geochemical data for samples from 55 postorogenic plutons of the southwestern Arabian Shield show that these granitoids are generally less evolved than similar granitoids of the eastern Arabian Shield. Radioelement contents are low to normal relative to typical granitic rocks and uranium contents are distinctly low relative to rocks of...
Hydrology of area 59, northern Great Plains and Rocky Mountain coal provinces, Colorado and Wyoming
Neville G. Gaggiani, Linda J. Britton, Donald R. Minges, F. A. Kilpatrick, Randolph S. Parker, James E. Kircher
1987, Open-File Report 85-153
Hydrologic information and analysis aid in decisions to lease federally owned coal and to prepare necessary Environmental Assessments and Impact Study reports. This need has become even more critical with the enactment of Public Law 95-87, the "Surface Mining Control and Reclamation Act of 1977." This act requires an appropriate...
Hydrology of area 8, eastern Coal Province, West Virginia and Ohio
E.A. Friel, T. A. Ehlke, W.A. Hobba Jr., S.M. Ward, R. A. Schultz
1987, Open-File Report 84-463
The hydrology of Area 8 in the Ohio River basin in northwestern West Virginia and southeastern Ohio, is influenced by geology and geologic structure. Rocks underlying the area consist of alternating beds of sandstone, siltstone, shale, limestone, and mudstone. Minable coal is contained within the Pennsylvania and Permian rocks. Coal...
Surface water-quality assessment of the lower Kansas River basin, Kansas and Nebraska; project description
J. K. Stamer, P. R. Jordan, R. A. Engberg, J. T. Dugan
1987, Open-File Report 87-105
In 1986 the U.S. Geological Survey began a National Water-Quality Assessment Program to: (1) provide nationally consistent descriptions of the current status of water quality for a large, diverse, and geographically distributed part of the Nation 's surface water resources; (2) where possible, define trends in water quality; and (3)...
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...
Documentation of a deep percolation model for estimating ground-water recharge
H. H. Bauer, J. J. Vaccaro
1987, Open-File Report 86-536
A deep percolation model, which operates on a daily basis, was developed to estimate long-term average groundwater recharge from precipitation. It has been designed primarily to simulate recharge in large areas with variable weather, soils, and land uses, but it can also be used at any scale. The physical and...
