Geohydrology of the Irondequoit Creek Basin near Rochester, New York
Richard M. Yager, Phillip J. Zarriello, William M. Kappel
1985, Water-Resources Investigations Report 84-4259
Geohydrologic information on the area within and surrounding the Irondequoit Creek basin near Rochester, in north-central New York, is presented on five maps at 1:24,000 scale indicating: (1) locations of glacial geomorphic features, (2) surficial geology, (3) soil permeability, (4) potentiometric-surface altitude and directions of groundwater movement, and (5) groundwater...
Hydrogeology of the Clifton Park area, Saratoga County, New York
Richard J. Reynolds
1985, Water-Resources Investigations Report 84-4031
The hydrogeology of the 75-square mile Clifton Park suburban area near Albany, N.Y., is presented in six maps at 1:24,000 scale. The maps show: (1) location of wells and test holes; (2) bedrock topography; (3) surficial geology and geologic sections; (4) saturated thickness of the confined aquifer; (5) generalized soil...
Estimating annual suspended-sediment loads in the northern and central Appalachian Coal region
G. F. Koltun
1985, Water-Resources Investigations Report 85-4215
Multiple-regression equations were developed for estimating the annual suspended-sediment load, for a given year, from small to medium-sized basins in the northern and central parts of the Appalachian coal region. The regression analysis was performed with data for land use, basin characteristics, streamflow, rainfall, and suspended-sediment load for 15 sites...
Streamflow and suspended-sediment discharge from two small watersheds in southwestern Wyoming and northeastern Utah, 1984
L.W. Lenfest Jr., B. H. Ringen
1985, Open-File Report 85-161
Accelerated erosion due to mineral exploration and production in southwestern Wyoming has caused concern that the streams will transport excess sediment in these areas. Two adjacent drainage basins with different levels of development were studied to determine the effects of minerals development on water quality. A high level of minerals...
Geologic characteristics of sediment- and volcanic-hosted disseminated gold deposits - Search for an occurrence model
Donald E. White, Robert O. Fournier, James J. Rytuba, Robert O. Rye, Charles G. Cunningham, Byron R. Berger, Miles L. Silberman, Harold F. Bonham Jr., Donald G. Strachan, Donald J. Birak, Robert J. Hawkins, Edwin W. Tooker
Edwin W. Tooker, editor(s)
1985, Bulletin 1646
The current expansion of resource information, particularly on "disseminated" gold, and the improved technologies now available for resource investigations should place us in an enhanced position for developing a better predictive methodology for meeting one of the important responsibilities of the U.S. Geological Survey-to examine and assess the mineral resources...
