Water availability of Choctaw County, Alabama
John G. Newton, Jerald F. McCain
1975, Open-File Report 75-477
Large quantities of ground water and surface water are available in Choctaw County. Major sources of ground water are the Nanafalia Formation, Tuscahoma Sand, Hatchetigbee Formation, and Gosport Sand and Lisbon Formation. The Nanafalia Formation is the most productive source of ground water, and individual wells will yield as much...
Optimizing information transfer in a stream-gaging network
Philip Hadley Carrigan Jr., Harold G. Golden
1975, Water-Resources Investigations Report 75-30
Networks of small stream (drainage area less than 50 square miles or 130 square kilometres) flood gages have been operated throughout the country for a number of years to supplement flood information already available for large streams. The goal in operating these networks has been to obtain sufficient data for...

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...
Sediment transport, turbidity, channel configuration, and possible effects of impoundment of the Mad River, Humboldt County, California
William M. Brown III
1975, Water-Resources Investigations Report 75-26
Sediment-transport conditions were determined at two stations, Mad River near Arcata and Mad River near Kneeland. Using a release-flow model and an empirical equation, the suspended-sediment discharge at Kneeland was estimated to be about 60 percent of the suspended-sediment discharge at the Arcata station. The study of the proposed impoundment...
Tectonic framework of petroliferous rocks in Alaska
Arthur Grantz, C.E. Kirschner
1975, Open-File Report 75-149
Alaska, comprising 3.6 X 106 sq km (about 28 percent) of the land, shelf, and upper continental slope of the United States, has been estimated by the U.S. Geological Survey (1974) to contain about 25 percent of the Nation's petroleum resources. Some 11 billion barrels of petroleum liquids and 31...
Reconnaissance engineering geology of the Ketchikan area, Alaska, with emphasis on evaluation of earthquake and other geologic hazards
Richard W. Lemke
1975, Open-File Report 75-250
The Alaska earthquake of March 27, 1964, dramatically emphasized the need for engineering geologic studies of urban areas in seismically active regions. A reconnaissance study of the Ketchikan area in southeastern Alaska is part of a program to evaluate earthquake and other geologic hazards in most of the larger Alaska...
In search of a statistical probability model for petroleum-resource assessment : a critique of the probabilistic significance of certain concepts and methods used in petroleum-resource assessment : to that end, a probabilistic model is sketched
Bernardo F. Grossling
1975, Circular 724
Exploratory drilling is still in incipient or youthful stages in those areas of the world where the bulk of the potential petroleum resources is yet to be discovered. Methods of assessing resources from projections based on historical production and reserve data are limited to mature areas. For most of the...
United States Geological Survey's hydrogeological research programs and plans related to disposal of radioactive waste into geologic formations
George D. DeBuchananne, William Stephens Twenhofel
1975, Open-File Report 75-626
The Geological Survey, United States Department of Interior, has cooperated with the United States Energy Research and Development Administration, formerly the Atomic Energy Commission, for more than 30 years on research related to the disposal of radioactive waste into geological formations. Results of most of this research effort have been...
Lithology and chemical analyses of core and cuttings from USGS drill hole near Gold Acres, Lander County, Nevada
Chester T. Wrucke
1975, Open-File Report 75-363
Upper Paleozoic to Mesozoic eolian blanket sandstones of the Colorado Plateau and the Rocky Mountains of Colorado and southern Wyoming are texturally complex. As petroleum reservoirs they commonly have poor performance histories. They contain the sediments of a depositional system comprised of three closely associated depositional subenvironments: dune, interdune, and...
Surface-water availability, Tuscaloosa County, Alabama
Alfred L. Knight, Marvin E. Davis
1975, Open-File Report 75-458
The average annual runoff, about 1,270 mgd (million gallons per day), originating in Tuscaloosa County is equivalent to 20 inches or 0.95 mgd per square mile. The Black Warrior and Sipsey Rivers, the largest streams in the county, have average flows of 5,230 mgd and 580 mgd, respectively, where they...

Notes on some experiments on the application of subtractive compensation to USGS seismic magnetic tape recording and playback systems
Jerry P. Eaton
1975, Open-File Report 75-663
The purpose of these experiments is to lay the groundwork for the implementation of subtractive compensation of the USGS seismic network tape playbacks utilizing the Develco model 6203 discriminators at a x1 playback speed. Although the Develco discriminators were designed for this application and a matching Develco compensation discriminator was...
A digital-computer model for estimating drawdowns in the sandstone aquifer in Dane County, Wisconsin
R.S. McLeod
1975, Open-File Report 74-59
A digital-computer program was developed to compute nonsteady and steady-state hydrologic changes caused by pumping from a confined aquifer. The program computes head changes in the confined aquifer and the rate and volume of water withdrawn from aquifer boundaries.The program was used to model the sandstone aquifer underlying Dane County,...
Rapid analysis of silicate, carbonate, and phosphate rocks: Revised edition
Leonard Shapiro
1975, Bulletin 1401
The rapid methods previously used by the U.S. Geological Survey to determine the major constituents of rocks have been modified to introduce atomic absorption spectrometry (AAS) where applicable. Two procedures are available for determining 10 constituents: one, from a single solution prepared by a nitric-acid dissolution of a lithium metaborate-lithium...
