Hydrogeologic conditions in the coastal plain of New Jersey
Eric F. Vowinkel, W. Kendall Foster
1981, Open-File Report 81-405
A wedge-shaped mass of unconsolidated sediments composed of alternating layers of clay, silt, sand, and gravel underlies the Coastal Plain of New Jersey. The hydrologic units of this mass vary in thickness, lateral extent, lithology, and water-bearing characteristics. Some of the units act as aquifers, whereas other units act as...
Publication search and retrieval system
Elizabeth A. Winget
1981, Open-File Report 81-1096
The publication search and retrieval system of the Branch of Atlantic-Gulf of Mexico Geology, U.S. Geological Survey, Woods Hole, Mass., is a procedure for listing and describing branch-sponsored publications. It is designed for maintenance and retrieval by those having limited knowledge of computer languages and programs. Because this branch currently...
Documentation of a dissolved-solids model of the Tongue River, southeastern Montana
Paul F. Woods
1981, Open-File Report 81-479
A model has been developed for assessing potential increases in dissolved solids of the Tongue River as a result of leaching of overburden materials used to backfill pits in surface coal-mining operations. The model allows spatial and temporal simulation of streamflow and dissolved-solids loads and concentrations under user-defined scenarios of...
Bed form distribution and inferred sand transport on Georges Bank
David C. Twichell
1981, Open-File Report 81-764
Four bed-form provinces have been identified on Georges Bank using sidescan sonar and echo-sounding techniques: large sand waves, small sand waves, megaripples, and featureless sea floor. The large sand waves are found on the bank crest where the surface tidal currents are strongest, and are bordered, north and south, by...
Water resources data for Texas, water year 1980, Volume 3: Colorado River basin, Lavaca River basin, Guadalupe River basin, Neces River basin, Rio Grande basin, and intervening coastal basins
United States Geological Survey
1981, Water Data Report TX-80-3
Surface-water data for the 1980 water year for Texas are presented in three volumes, appropriately identified as to content by river basins. Data in each volume consist of records of stage, discharge, and water quality of streams and canals; and stage, contents, and water quality of lakes and reservoirs. Also...
Surficial geology of Hannibal quadrangle, Oswego County, New York
Todd S. Miller
1981, Open-File Report 81-129
The location and extent of 10 kinds of surficial deposits in part of Hannibal quadrangle, Oswego County, N.Y., are mapped on a 7.5-minute U.S. Geological Survey topographic map. The map was compiled to indicate the lithology and potential for ground-water development at any specific location. (USGS)...
Stream-sediment geochemical survey of the Bureau of Land Management's Arkansas Canyon Planning Unit in south-central (Canon City area) Colorado
Erick F. Weiland, Richard I. Grauch
1981, Open-File Report 81-673
A mineral assessment study was undertaken by Barringer Resources, Inc., Golden, Colorado, on behalf of the Bureau of Land Management covering the Arkansas Canyon Planning Unit in south-central Colorado near Canon City. A total of 700 stream-sediment samples were collected (Plate I) and subsequently analyzed by Barringer Resources....
Floodflow characteristics related to channel geometry in Ohio
E.E. Webber, J.W. Roberts
1981, Open-File Report 81-1105
Techniques for estimating magnitude and frequency of flood-peak discharges, based on channel geometry parameters, are presented as a method for evaluating Ohio floods in geographic areas deficient in flow data. One hundred and sixty gaging stations were selected on streams with alluvial channels unaltered by man. Exposed bedrock is absent...
Decentralized shared computers in the National Earthquake Hazards Reduction Program
Peter L. Ward, James Herriot, William F. Jolitz
1981, Open-File Report 81-104
The needs for computer analysis in the National Earthquake Program are varied, complex, and rapidly growing. Major sources of frustration have been the difficulty of keeping up with the required analysis, and the difficulties of sharing a wide variety of data and computer programs among several hundred researchers at dozens...
