A qualitative appraisal of the hydrology of the Yemen Arab Republic from Landsat images
Maurice J. Grolier, G. Chase Tibbitts, M.M. Ibrahim
1981, Open-File Report 80-565
Landsat-1 and Landsat-2 images were analyzed in June 1976 to describe the flow regimens of streams and the regional distribution of vegetation in the Yemen Arab Republic (YAR). The findings provide a factual basis for planning a surface-water data collection program, and for preparing maps of plant distribution and agricultural...
Seismicity map of the state of North Dakota
B.G. Reagor, C. W. Stover, S. T. Algermissen
1981, Miscellaneous Field Studies Map 1326
The earthquake data shown on this map and listed in table 1 are a list of earthquakes that were originally used in preparing the Seismic Risk Studies in the United States in the United States (Algermissen, 1969) which have been recompiled and updated through 1977.  These data have been reexamined...
Seismicity map of the state of South Dakota
B.G. Reagor, C. W. Stover, S. T. Algermissen
1981, Miscellaneous Field Studies Map 1325
The earthquake data shown on this map and listed in table 1 are a list of earthquakes that were originally used in preparing the Seismic Risk Studies in the United States in the United States (Algermissen, 1969) which have been recompiled and updated through 1977.  These data have been reexamined...
Map showing paleontological control of Paleozoic stratigraphy in New England
Marland P. Billings, Peter T. Lyttle
1981, Miscellaneous Field Studies Map 1302
Assignment of Phanerozoic stratigraphic units to their proper place in the geologica time scale is based primarily on paleontology.  Radiometric methods are becoming increasingly important (Naylor, 1976), particularly where paleontological data are lacking.  This map and text are concerned only with the paleontological data bearing on the Paleozoic stratigraphy of...
Mineral resource potential of the Baker-Cypress BLM Instant Study Area and Timbered Crater Forest Service Further Planning (RARE II) Areas, Modoc, Shasta, and Siskiyou Counties, California
Jocelyn A. Peterson, L.M. Martin, L. E. Esparza, Gary J. Cwick
1981, Miscellaneous Field Studies Map 1214-B
In accordance with the provisions of the Federal Land Policy and Management Act (Public Law 94-579, October 21, 1976), the Geological Survey and the Bureau of Mines have conducted mineral surveys on certain areas, which formally had been identified as "natural" and "primitive" areas prior to November 1, 1975.The Wilderness...
Variations in climatic characteristics as related to evapotranspiration in South Park, central Park County, Colorado
Norman E. Spahr
1981, Water-Resources Investigations Report 80-86
Data collected from May through September in 1977, 1978, and 1979 at three stations were analyzed using an analysis of variance technique to determine variations in climatic characteristics in South Park, Colo. Knowledge of these climatic characteristics will aid in determining the amount of water that may be transferred from...
Digital models of ground-water flow in the Cape Cod aquifer system, Massachusetts
John H. Guswa, Denis R. LeBlanc
1981, Open-File Report 80-67
The Cape Cod aquifer system was simulated with three-dimensional finite-difference ground-water-flow models. Five areas were modeled to provide tools that can be used to evaluate the hydrologic impacts of regional water development and waste disposal.The model boundaries were selected to represent the natural hydrologic boundaries of the aquifer. The boundary...
Tabulation of the ostracode assemblages and associated organisms from selected bottom grab samples taken in the northeast Gulf of Alaska, F.R.S. Townsend Cromwell Cruise IGAL-75-KC, 1975
Elisabeth M. Brouwers
1981, Open-File Report 81-1314
The U.S. Geological Survey is conducting studies of the Alaskan continental shelf, identifying areas and processes of geological hazard that may affect resource development offshore. These hazards include areas of rapid accumulation of unconsolidated sediment, areas of intense erosional activity, and regions of submarine sliding and slumping; shallow faults are...
Outline for a hydrologic data base for Portugal
Norman E. Hutchison
1981, Open-File Report 81-424
The Agency for International Development requested the assistance of the U.S. Geological Survey (USGS) to help the Government of Portugal in the investigation and management of ground water resources in the Algarve region. The assistance was to be provided in four specialty areas, but the scope of this report is...
Hydrology of area 4, Eastern Coal Province, Pennsylvania, Ohio, and West Virginia
Donald K. Roth, Morris J. Engelke Jr., and others
1981, Open-File Report 81-343
Area 4 (one of the 24 hydrologic areas defining the Eastern Coal Province) is located at the northern end of the Eastern Coal Province in eastern Ohio, northern West Virginia, and western Pennsylvania. It is part of the upper Ohio River basin, which includes the Beaver, Mahoning, and Shenango Rivers....
Ground-water resources of the White River basin, Madison County, Indiana
Wayne W. Lapham
1981, Water-Resources Investigations Report 81-35
The ground-water resources of the White River basin in and near Madison County, Indiana, were investigated by mapping the aquifers, estimating their hydraulic properties, determining the distribution of potentiometric head in the aquifers, and estimating some of the components of the ground-water budget from data collected in the field. This...
Limnological and geochemical survey of Williams Lake, Hubbard County, Minnesota
J. W. LaBaugh, G.E. Groschen, Thomas C. Winter
1981, Water-Resources Investigations Report 81-41
A limnological and geochemical survey of Williams Lake, Minnesota, was made in 1979 to provide an initial interpretive description of the lake and the contiguous ground-water system. This survey was made as part of a continuing research program related to the investigation of the interaction of lakes and their contiguous...
Kriging analysis of mean annual precipitation, Powder River Basin, Montana and Wyoming
M.R. Karlinger, James A. Skrivan
1981, Water-Resources Investigations Report 80-50
Kriging is a statistical estimation technique for regionalized variables which exhibit an autocorrelation structure. Such structure can be described by a semi-variogram of the observed data. The kriging estimate at any point is a weighted average of the data, where the weights are determined using the semi-variogram and an assumed...
Records of water levels in unconsolidated deposits in eastern South Dakota
Wendell L. Bradford

William J. Carswell Jr.
1981, Water-Resources Investigations Report 81-8
Hydrologic data from Soldier Creek basin were compared with relations from statewide data. The quantity and quality of streamflow were affected mostly by soils, slopes, and land use. Average annual precipitation during the study (196476) was 35.12 inches, or 2.3 percent greater than the long-term (1929-76) average. The average streamflow...
