The environment of south-central Tunisia as observed on Landsat scene 206/036
M. J. Grolier, P.A. Schultejann
1982, Open-File Report 82-130
One Landsat image in south-central Tunisia was analyzed to demonstrate the application of remote-sensing technology to regional development. A preliminary analysis included I) major landscape features; 2) gypsum-encrusted soils; and 3) phosphate-bearing beds exposed in the Gafsa mining district. The products specifically used for this report include: 1) A false-color...
Annual Nutrient Loadings, Primary Productivity, and Trophic State of Lake Koocanusa, Montana and British Columbia, 1972-80
Paul F. Woods
1982, Professional Paper 1283
Limnological data collected at Lake Koocanusa were used to investigate the relationship of nutrient loadings, primary productivity, and trophic state of the reservoir during 1972-80. The reservoir, on the Kootenai River, was impounded by Libby Dam on March 21, 1972. Manipulation of the 7.16-cubic-kilometer reservoir for flood control, its primary...
Diatremes of the Hopi Buttes, Arizona; chemical and statistical analyses
K. J. Wenrich, J. F. Mascarenas
1982, Open-File Report 82-740
Lacustrine sediments deposited in maar lakes of the Hopi Buttes diatremes are hosts for uranium mineralization of as much as 1500 ppm. The monchiquites and limburgite turfs erupted from the diatremes are distinguished from normal alkalic basalts of the Colorado Plateau by their extreme silica undersaturation and high water, TiO2,...
Habitat Suitability Index Models: Eastern meadowlark
Richard L. Schroeder, Patrick J. Sousa
1982, FWS/OBS 82/10.29
Habitat preferences of the eastern meadowlark (Sturnella magna) are described in this publication, which is one of a series of Habitat Suitability Index (HSI) models. Habitat use information is presented in a synthesis of the literature on the species-habitat requirements of the eastern meadowlark, followed by the development of the...
The depositional environment and petrology of the White Rim Sandstone Member of the Permian Cutler Formation, Canyonlands National Park, Utah
B. A. Steele-Mallory
1982, Open-File Report 82-204
The White Rim Sandstone Member of the Cutler Formation of Permian age in Canyonlands National Park, Utah, was deposited in coastal eolian and associated interdune environments. This conclusion is based on stratigraphic relationships primary sedimentary structures, and petrologic features. The White Rim consists of two major genetic units. The first...
Ground-water data for Georgia, 1981
S.E. Matthews, Willis G. Hester, K.W. McFadden
1982, Open-File Report 82-904
More than 2,000 water-level measurements made in Georgia in 1981 provide the basic data for this report. Daily mean water-level fluctuations and trends are shown in hydrographs for the previous year (1980) and fluctuations of the monthly mean water levels are shown for selected years in some observation wells in...
A summary of selected publications, project activities, and data sources related to hydrology in the Warrior and Plateau coal fields of Alabama
Robert E. Kidd, Thomas J. Hill
1982, Open-File Report 82-913
The report is a reference source on hydrologic information related to coal-mining activities in the Warrior and Plateau coal fields of Alabama. It contains a bibliography of more than 200 references and selected annotations. Also included is information on maps, automated-data bases, water-monitoring programs, and data-source agencies and organizations....
Water resources data Iowa, water year 1981
Water Resources Division, U.S. Geological Survey
1982, Water Data Report IA-81-1
This report was prepared by personnel of the Iowa district of the Water Resources Division of the U.S. Geological Survey under the supervision of 0. G. Lara, Acting District Chief, and Alfred Clebsch, Jr., Regional Hydrologist, Central Region. It was done in cooperation with the State of Iowa and with other agencies. This report is...
Characteristics of suspended sediment in the San Juan River near Bluff, Utah
K. R. Thompson, J. C. Mundorff
1982, Water-Resources Investigations Report 82-4104
Fluvial-sediment data were collected for the San Juan River near Bluff beginning in 1914 and terminating in 1980. A double-mass curve showed a change in relationship between annual suspended-sediment discharge and annual stream discharge between the water years 1941-44 and 73. Possible causes for these changes in laboratory procedures, and...
Determination of the true density of pulverized coal samples
R.W. Stanton
1982, Open-File Report 82-835
A method using the gas-comparison pycnometer with helium gas as the penetrating medium measures precisely the true volume of a pulverized coal sample. The true density of a solid is calculated as the true unit volume of the solid exclusive of its pore space which is divided into the weight...
Use of a three-dimensional model for the analysis of the ground-water flow system in Parker Valley, Arizona and California
Patrick Tucci
1982, Open-File Report 82-1006
A three-dimensional, finite-difference model was used to simulate ground-water flow conditions in Parker Valley. The study evaluated present knowledge and concepts of the ground-water system and the ability of the model to represent the system. Modeling assumptions and generalized physical parameters that were used may have transfer value in the...
