Water-quality data for two surface coal mines reclaimed with alkaline waste or urban sewage sludge, Clarion County, Pennsylvania, May 1983 through November 1989
D.L. Dugas, C.A. Cravotta III, D. A. Saad
1993, Open-File Report 93-115
Water-quality and other hydrologic data for two surface coal mines in Clarion County, Pa., were collected during 1983-89 as part of studies conducted by the U.S. Geological Survey in cooperation with the Pennsylvania Department of Environmental Resources. Water samples were collected from streams, seeps, monitor wells, and lysimeters on a...
Geohydrology and evaluation of water-resource potential of the upper Floridan Aquifer in the Albany area, southwestern Georgia
L.J. Torak, G. S. Davis, G.A. Strain, J.G. Herndon
1993, Water Supply Paper 2391
In the Albany area of southwestern Georgia, the Upper Floridan aquifer lies entirely within the Dougherty Plain district of the Coastal Plain physiographic province, and consists of the Ocala Limestone of late Eocene age. The aquifer is divided throughout most of the study area into an upper and a lower...
Methods for sampling fish communities as part of the National Water-Quality Assessment Program
M. R. Meador, T. F. Cuffney, M. E. Gurtz
1993, Open-File Report 93-104
Fish community structure is characterized in the U.S. Geological Survey's National Water-Quality Assessment Program as part of an integrated physical, chemical, and biological assessment of the Nation's water quality. The objective of the National Water-Quality Assessment characterization of fish community structure is to relate fish community characteristics to physical, chemical,...
Geologic studies in Alaska by the U.S. Geological Survey, 1992
Cynthia Dusel-Bacon, Alison B. Till, editor(s)
1993, Bulletin 2068
This collection of 19 papers continues the annual series of U.S. Geological Survey reports on the geology of Alaska. The contributions, which include full-length Articles and shorter Geologic Notes, cover a broad range of topics including dune formation, stratigraphy, paleontology, isotopic dating, mineral resources, and tectonics. Articles, grouped under four...
Estimation of unit hydrographs for large floods at ungaged sites in Montana
S.R. Holnbeck, Charles Parrett
1993, Open-File Report 93-168
Methods were developed for estimating unit hydro- graphs at ungaged sites in Montana using either the Clark or dimensionless unit-hydrograph method. Flood hydrograph data for 26 U.S. Geological Survey streamflow-gaging stations and rainfall data were used together with a rainfall-runoff simulation model (HEC-1) to derive unit hydrographs and important unit-hydrograph...
