Textural composition of shallow cores from the tidal Potomac River and Estuary; 1978 and 1979
E. Ann Martin, J.L. Glenn, A. Varga, J. Benton, E. Gum, J. Gray
1981, Open-File Report 81-1355
During 1978 and 1979, 37 cores were collected by divers from the tidal Potomac River system and from adjacent marginal embayments. These cores, approximately 1 m in length, are representative of geomorphic divisions within the riverine, transitional, and estuarine parts of the Potomac and of several tributaries. X-radiographs were made...

Ground-water hydrology of strip-mine areas in eastern Ohio (conditions during mining of two watersheds in Coshocton and Muskingum counties)
John O. Helgesen, Allan C. Razem
1981, Open-File Report 81-913
Ground-water conditions during coal strip mining in two small watersheds are described as part of an ongoing study of effects of mining on hydrologic systems. Both watersheds were underlain by stratified sedimentary rocks containing two perched aquifers above clay beds which underlaid the major coal seams. Mining involved removing the...

Ground-water hydrology of the Mormon Island Crane Meadows wildlife area near Grand Island, Hall County, Nebraska
R. Theodore Hurr
1981, Open-File Report 81-1109
The Platte River in south-central Nebraska flows generally eastward in a broad, flat valley. The river banks and many areas adjacent to the river support thick stands of cottonwood and willow trees. Brush, grass, pasture land, and cultivated fields occupy most of the remaining area. This is the habitat for...

Catalog of earthquakes along the San Andreas fault system in central California, July-September 1977
S.M. Marks, L. Fluty
1981, Open-File Report 81-462
Numerous small earthquakes occur each day in the Coast Ranges of central California. The detailed study of these earthquakes provides a tool for gaining insight into the tectonic and physical processes responsible for the generation of damaging earthquakes. This catalog contains the fundamental parameters for earthquakes located within and adjacent...
Cedar Creek at Cedartown, Georgia, floodflow characteristics from West Girard Avenue to the Georgia Avenue Relocation
McGlone Price
1981, Open-File Report 82-122
In cooperation with the Highway Division, Georgia Department of Transportation, the U.S. Geological Survey determined the backwater effects of existing bridges and dikes on Cedar Creek at Cedartown, Georgia, for the reach from West Girard Avenue to the Georgia Avenue relocation. The maximum backwater effect for the bridges was 1.7...
