The Black Hills-Rapid City flood of June 9-10, 1972: A description of the storm and flood
Francis K. Schwarz, L.A. Hughes, E.M. Hansen, M.S. Petersen, Donovan B. Kelly
1975, Professional Paper 877
On June 9, 1972, an almost stationary group of thunderstorms formed over the eastern Black Hills of South Dakota near Rapid City and produced record amounts of rainfall and flood discharges. Nearly 15 inches of rain fell in about 6 hours near Nemo, S. Dak., and more than 10 inches...
Summary of floods in the United States during 1969
J.K. Reid
1975, Water Supply Paper 2030
The most outstanding floods in the United States during 1969 are described in chronological order. The areas most seriously affected by flooding were: Central and southern California (January and February); the upper Midwestern States of North Dakota, South Dakota, Minnesota, Iowa, Wisconsin, and Illinois (April); north-central Ohio (July); Mississippi, Alabama,...
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...
Selenium in waters in and adjacent to the Kendrick Project, Natrona County, Wyoming
Marvin A. Crist
1975, Water Supply Paper 2023
Selenium in concentrations exceeding the maximum limit, 0.01 milligrams per liter or 10 micrograms per liter, recommended by the U.S. Public Health Service in 'Drinking-Water Standards, 1962,' Public Health Pub. 956, is present in waters in areas near Casper, Wyo. Some streams containing selenium flow into the North Platte River...
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...
Digital-simulation and projection of water-level declines in basalt aquifers of the Odessa-Lind area, east-central Washington
J. E. Luzier, James A. Skrivan
1975, Water Supply Paper 2036
A digital computer program using finite-difference techniques simulates an intensively pumped, multilayered basalt-aquifer system near Odessa. The aquifers now developed are in the upper 1,000 feet of a regionally extensive series of southwesterly dipping basalt flows of the Columbia River Group. Most of the aquifers are confined. Those in the...
Effects of organic solutes on chemical reactions of aluminum
Carol J. Lind, John David Hem
1975, Water Supply Paper 1827-G
Concentrations of organic matter in the general range of 1-10 milligrams per litre organic carbon are common in natural water, and many naturally occurrin7 organic compounds form aluminum complexes. The aluminum concentrations in near-neutral pH solutions may be 10-100 times higher than the values predicted from solubility data if formation...
Aluminum resources of Brazil
Max Gregg White
1975, Open-File Report 75-30
Large deposits of bauxite, the principal ore of aluminum, occur at several places in Brazil. The largest deposits now undergoing extensive exploration and development are in the eastern Amazon Basin. Most of these deposits are in the State of Para, but some are in Amazonas and Maranhao.Discovery of large-scale resources...
Copper, lead, zinc, antimony, and arsenic in Pakistan
Max Gregg White
1975, Open-File Report 75-162
Copper localities that merit geological investigation are found in the western Chasai District, in North Waziristan Agency, and in the Salt Range in Mianwali and Sargodha Districts. No high-grade deposits have been .reported from these ,areas and if deposits are developed they will likely be low-grade, high-tonnage, disseminated deposits. Those...
Ground-water resources of Greeley and Wichita counties, Western Kansas
Steven E. Slagle, Edward C. Weakly
1975, Open-File Report 75-557
Unconsolidated deposits of sand, silt, clay, and gravel compose the principal aquifer in Greeley and Wichita Counties. The deposits are as much as 300 feet (91 m) 2/ thick, of which as much as 145 feet (44 m) is saturated.In 1972, there were about 1,040 large-capacity wells--yielding 100 gallons per...
