Chemical interactions of aluminum with aqueous silica at 25 degrees Celsius
John David Hem, C. E. Roberson, Carol J. Lind, W.L. Polxer
1973, Water Supply Paper 1827-E
Solutions containing from 10 -5 to 10 -2 moles per liter of aluminum and dissolved silica in various ratios were aged at pH levels between 4 and 10 at 25?C. A colloidal amorphous product having the composition of halloysite was produced in most solutions. It had a consistent and reversible...
Records of selected water wells and test holes in the Oklahoma Panhandle
George L. Hoffman, Donald L. Hart Jr.
1973, Open-File Report 73-376
Since 1963 use of ground water for irrigation in the Oklahoma panhandle has increased greatly as illustrated by the rapid increase in the number of irrigation wells (fig. 1). Because of increased use of ground water, the U.S. Geological Survey, in cooperation with the Oklahoma Water Resources Board, in 1966...
Water resources outlook for the Minneapolis-Saint Paul Metropolitan Area, Minnesota
R.F. Norvitch, T.G. Ross, Alex Brietkrietz
1973, Open-File Report 73-203
The water resources were studied within an area whose natural ground-water flow is largely towards the center of the metropolitan area. This area coincides with the extent of the Hinckley Sandstone aquifer. Thus, the general geohydrology of the area bounded by the extent of the Hinckley Sandstone (about 6,000 square...
Flood of September 1971 in southeastern Pennsylvania
Leland V. Page, Lewis C. Shaw
1973, Open-File Report 73-217
Record-breaking floods on Sept. 13, 1971, occurred in some urbanized basins of southeastern Pennsylvania. This flooding resulted from heavy, intermittent thunderstorms on Sept. 11-13, 1971, which produced 8 to 12 inches of rainfall in the basins of Skippack, Stony, and Chester Creeks. Rain was heaviest during mid-day of the 13th....
Wolf River at Memphis, Tennessee: floodflow characteristics along proposed Interstate Highway 240, Shelby County
William J. Randolph, Charles R. Gamble
1973, Open-File Report 73-228
This report has been prepared by the U.S. Geological Survey at the request of Mr. Henry Derthick, Engineer of Structures of the Tennessee Department of Transportation, under the authority of a cooperative agreement between the two agencies. It supplements information contained in a report with the same title dated September...
Velocity and depth measurements for use in computation of reaeration coefficients
John S. Zogorski, Peter W. Anderson, Owen O. Williams
1973, Open-File Report 73-369
Empirical computation of reaeration coefficients generally requires knowledge of mean velocity and mean depth of a stream. A practical method for obtaining this knowledge is described herein. The method involves time-of-travel, streamflow, and cross-sectional measurements, the development of discharge-velocity curves, streamflow profiles, and the computation of cross-sectional areas. Values for...
Water resources of Wisconsin, Pecatonica-Sugar River basin
S. M. Hindall, Earl L. Skinner
1973, Hydrologic Atlas 453
The purpose of this report is to describe the physical environment, availability, characteristics, distribution, movement, and quailty of water in the Pecatonica-Sugar River basin.  In addition, water use and water problems are summarized to give an understanding of man's management of water within the basin....
