Geohydrologic reconnaissance of the upper Potomac River basin
Frank W. Trainer, Frank A. Watkins
1975, Water Supply Paper 2035
The upper Potomac River basin, in the central Appalachian region in Pennsylvania, Maryland, Virginia, and West Virginia, is a humid temperate region of diverse fractured rocks. Three geohydrologic terranes, which underlie large parts of the basin, are described in terms of their aquifer characteristics and of the magnitude and duration...
Simulated drawdown for selected well fields in the Ohio River alluvial aquifer
Hayes F. Grubb
1975, Water-Resources Investigations Report 74-2
Drawdown due to pumping was simulated for three sites in the alluvial aquifer adjacent to the Ohio River by digital modeling techniques. Two well-field arrangements were used at each site. The initial well-field arrangement at each site consisted of three wells located in a line parallel to the Ohio River....
Titanium minerals in deposits of other minerals
Eric R. Force
1975, Open-File Report 75-34
Titanium minerals in amounts equivalent to a significant portion of present world production are moved but not recovered from mines of other commodities. Resources of this type total in the millions of tons of contained TiO2. Among the possible sources for byproduct titanium are (1) ilnenite and minor rutile detrital...
Map showing availability of hydrologic data published by the U.S. Environmental Data Service and by the U.S. Geological Survey and cooperating agencies, greater Denver area, Front Range Urban Corridor, Colorado
E. R. Hampton
1975, IMAP 856-C
What is the rainfall of this region? What areas are prone to periodic flooding? What is the water supply? What is the chemical quality of the ground water and water in the streams? How deep is the water table? Which streams are gaged, and where? These and similar questions are...
Bedrock topography of northeast Iowa
Robert E. Hansen
1975, IMAP 933
The bedrock in Iowa (Hershey, 1969) is generally overlain by deposits of glacial drift and alluvium, which range in thickness from less than 1 foot (0.3 m) to more than 400 ft (18 m), respectively. The configuration of the bedrock surface is the result of a complex system of ancient...
Preliminary hydrogeologic appraisal of selected hydrothermal systems in northern and central Nevada
F. H. Olmsted, P.A. Glancy, J. R. Harrill, F. E. Rush, A. S. Van Denburgh
1975, Open-File Report 75-56
Several hydrothermal systems in northern and central Nevada were explored in a hydrogeologic reconnaissance. The systems studied comprise those at Stillwater and Soda Lakes-Upsal Hogback in the Carson Desert, Gerlach, Fly Ranch-Granite Range, and Double Hot Springs in the Black Rock Desert, Brady's Hot Springs, Leach Hot Springs in Grass...
Satellite relay and processing of hydrologic data in south Florida
E.T. Wimberly
1975, Water-Resources Investigations Report 75-12
Management of water in south Florida requires current hydrologic data on water levels and rainfall. This need is being met by a data processing system which provides near-real-time data from remote areas. The flow of data is from data-collection platforms at field sites via LANDSAT-1 satellite to the National Aeronautics...
Water resources of the Lake of the Woods watershed, north-central Minnesota
John O. Helgesen, Gerald F. Lindholm, Donald W. Ericson
1975, Hydrologic Atlas 544
The Lake of the Woods watershed is an area of about 2,900 square miles (7,500 km), the northern limit of which is part of the boundary between the United States and Canada. Drainage is to Lake of the Woods, either directly or by the Rainy River. The watershed includes about...
Water resources data for Kansas, water year 1974; Part 1, Surface water records
Water Resources Division, U.S. Geological Survey
1975, Water Data Report KS-74-1
Water resources data for the 1974 water year for Kansas including records of stream-flow or reservoir storage at gaging stations, partial-record stations, and miscellaneous sites are given in this report. Records are included for 163 gaging stations of which 143 are streamflow discharge stations and 20 are reservoir or lake...
Reactions of aqueous aluminum species at mineral surfaces
David Wayne Brown, John David Hem
1975, Water Supply Paper 1827-F
Aqueous aluminum solutions containing 4.5 ? 10 4 molar aluminum in 0.01 molar NaC104 were partly neutralized with NaOH to give OH:A1 mole ratios from 1.40 to 2.76. Measured amounts of montmorillonite, kaolinite, volcanic ash, or feldspathic sand were added to provide an area of inert surface. Reactions that occurred...
