Optimal exploitation strategies for an animal population in a stochastic serially correlated environment
David R. Anderson
1974, Dissertation Abstracts International (35) 3107
Optimal exploitation strategies were studied for an animal population in a stochastic, serially correlated environment. This is a general case and encompasses a number of important cases as simplifications. Data on the mallard (Anas platyrhynchos) were used to explore the exploitation strategies and test several hypotheses because relatively...

Optimal exploitation strategies were studied for an animal population in a stochastic, serially correlated environment. This is a general case and encompasses a number of important cases as simplifications.

Thin and layered subcontinental crust of the Great Basin western North America inherited from Paleozoic marginal ocean basins?
Michael Churkin Jr., E.H. McKee
1974, Tectonophysics (23) 1-15
The seismic profile of the crust of the northern part of the Basin and Range province by its thinness and layering is intermediate between typical continental and oceanic crust and resembles that of marginal ocean basins, especially those with thick sedimentary fill. The...
A special planning technique for stream-aquifer systems
C.T. Jenkins, O. James Taylor
1974, Open-File Report 74-242
The potential effects of water-management plans on stream-aquifer systems in several countries have been simulated using electric-analog or digital-computer models. Many of the electric-analog models require large amounts of hardware preparation for each problem to be solved and some become so bulky that they present serious space and access problems....
Some aspects of remote sensing for consideration in planning for environmental monitoring of the Alyeska Pipeline, Alaska
Herbert E. Skibitzke
1974, Open-File Report 77-643
Remote sensing data were taken along a line surveyed for the building of the Alyeska Pipeline, Alaska, in the winter of 1973-74. The portion considered in this report is the area from the Yukon River south to Isabel Pass in the Alaska Range. The occurrences of aufeis gave the appearance...

A program to compute aquifer-response coefficients
Thomas Maddock
1974, Open-File Report 75-612
An alternating direction technique is used to solve finite difference equations approximating the flow of water in an aquifer. The solutions produce response coefficients relating pumping from wells to drawdowns within those wells. The product of the response coefficient with the pumping values produces a linear algebraic technological function that...
Analog-model studies of ground-water hydrology in the Houston District, Texas
Donald G. Jorgensen
1974, Open-File Report 74-113
The major water-bearing units in the Houston district are the Chicot and the Evangeline aquifers. The Chicot aquifer overlies the Evangeline aquifer, which is underlain by the Burkeville confining layer. Both aquifers consist of unconsolidated and discontinuous layers of sand and clay that dip toward the Gulf of Mexico. Heavy...

Model synthesis in frequency analysis of Missouri floods
Leland D. Hauth
1974, Circular 708
Synthetic flood records for 43 small-stream sites aided in definition of techniques for estimating the magnitude and frequency of floods in Missouri. The long-term synthetic flood records were generated by use of a digital computer model of the rainfall-runoff process. A relatively short period of concurrent rainfall and runoff data...

An investigation of basin effects on flood discharges in North Dakota
Orlo A. Crosby
1974, Open-File Report 74-346
An investigation of the relationship of peak discharge to causative storm variables and drainage-basin characteristics was made to provide guidelines for future analyses of frequency and magnitudes of floods from small drainage areas. The procedure used was (l) to estimate peak discharges on the ll study basins from multiple-regression models developed from the storm variables and...
Streamflow measurement network review for hydroelectric power applications in Brazil
Francis T. Schaefer
1974, Open-File Report 74-357
This review of selected segments of the stream-gaging network of Brazil was undertaken by the writer in March and April, 1973, pursuant to an agreement between Companhia de Pesquisa de Recursos Minerais (CPRM) and Centrais Eletricas Brasileiras S.A. (ELETROBRAS) as a part of the cooperative program of the U.S. Geological...
Summary of tectonic and structural evidence for stress orientation at the Nevada Test Site
Wilfred James Carr
1974, Open-File Report 74-176
A tectonic synthesis of the NTS (Nevada Test Site) region, when combined with seismic data and a few stress and strain measurements, suggests a tentative model for stress orientation. This model proposes that the NTS is undergoing extension in a N. 50 ? W.-S. 50 ? E. direction coincident with...

Water demands for expanding energy development
G. H. Davis, Leonard A. Wood
1974, Circular 703
Water is used in producing energy for mining and reclamation of mined lands, onsite processing, transportation, refining, and conversion of fuels to other forms of energy. In the East, South, Midwest, and along the seacoasts, most water problems are related to pollution rather than to water supply. West of about...
Recommendations for the study and appraisal of oil-shale deposits in Jordan
Vernon Emanuel Swanson
1974, Open-File Report 74-197
A geologic-geochemical evaluation conducted October 5-24, 1968, both in the field area and in the laboratories has shown the Upper Cretaceous oil shale in the El Lajjun area of central Jordan to be one of Jordan's major natural mineral resources. Continued but slightly modified investigations are strongly recommended to determine...

Influence of recharge basins on the hydrology of Nassau and Suffolk Counties, Long Island, New York
G.E. Seaburn, D. A. Aronson
1974, Water Supply Paper 2031
An investigation of recharge basins on Long Island was made by the U.S. Geological Survey in cooperation with the New York State Department of Environmental Conservation, Nassau County Department of Public Works, Suffolk County Department of Environmental Control, and Suffolk County Water Authority.

Seismic hazards and land-use planning
Donald R. Nichols, Jane M. Buchanan-Banks
1974, Circular 690
Basic earth-science data are necessary for a realistic assessment of seismic hazards and as a basis for limiting corrective land-use controls only to those areas of greatest hazard. For example, the location, character, and amount of likely displacement and activity of surface faulting can be predicted if detailed geologic maps...
Gold in the Black Hills, South Dakota, and how new deposits might be found
James Jennings Norton
1974, Circular 699
Of the recorded production of 34,694,552 troy ounces of gold mined in South Dakota through 1971, about 90 percent has come from Precambrian ore bodies in the Homestake mine at Lead in the northern Black Hills. Most of the rest has come from ore deposited in the Deadwood Formation (Cambrian)...
Molybdenite in the Montezuma District of central Colorado
George J. Neuerburg, Theodore Botinelly, John R. Watterson
1974, Circular 704
The Montezuma mining district, in the Colorado mineral belt, is defined by an assemblage of porphyry, ore, and altered rocks that originated in the venting of a Tertiary batholith through weak structures in Precambrian rocks. The ore consists of silver-lead-zinc veins clustered on the propylitic fringe of a geometrically complex...

1974, Open-File Report 74-39
The Dismal Swamp, on the border between eastern Virginia and North Carolina is one of the few remaining large (approximately 210,000 acres) areas of wet wilderness in the eastern United States. There has been much speculation concerning the hydrologic conditions that led to the formation of the swamp.Oaks and Coch...
