Habitat suitability index models: Channel catfish
Thomas E. McMahon, James W. Terrell
1982, FWS/OBS 82/10.2
The native range of channel catfish (Ictalurus Runctatus) extends from the southern portions of the Canadian prairie provinces south to the Gulf states, west to the Rocky Mountains, and east to the Appalachian Mountains (Trautman 1957; Miller 1966; Scott and Crossman 1973). They have been widely introduced outside this range...
Drainage divides, Massachusetts; Blackstone and Thames River basins
Bruce E. Krejmas, S. William Wandle
1982, Open-File Report 82-631
Drainage boundaries for selected subbasins of the Blackstone and Thames River basins in eastern Hampden, eastern Hampshire, western Norfolk, southern Middlesex, and southern Worcester Counties, Massachusetts, are delineated on 12 topographic quadrangle maps at a scale of 1:24,000. Drainage basins are shown for all U.S. Geological Survey data-collection sites and...
Near-station terrain corrections for gravity data by a surface-integral technique
M. E. Gettings
1982, Open-File Report 82-1045
A new method of computing gravity terrain corrections by use of a digitizer and digital computer can result in substantial savings in the time and manual labor required to perform such corrections by conventional manual ring-chart techniques. The method is typically applied to estimate terrain effects for topography near the...
Johnstown-western Pennsylvania storms and floods of July 19-20, 1977
L. Ray Hoxit, Robert A. Maddox, Charles F. Chappell, Stan A. Brua
1982, Professional Paper 1211
Widespread thunderstorms associated with two major squall lines, moved across Pennsylvania between the afternoon of July 19 and morning of July 20, 1977. The western part of outflow boundary produced by the second line became almost stationary in western Pennsylvania and resulted in 6 to 9 hours of nearly continuous...
Activities in Idaho; status of projects, fiscal years 1982-83
Linda K. Channel (compiler)
1982, Open-File Report 83-40
Twenty-three projects were conducted by the Water Resources Division of the U.S. Geological Survey in Idaho during FY 's (fiscal year) 1982-83. These projects were done in cooperation with seven State and local and nine federal agencies. State and local cooperative funding amounted to $566,123 in FY 1982 and $570,000...
The economic feasibility of operational earth sensing from space
Alden P. Colvocoresses
1982, Open-File Report 82-250
Earth-sensing satellites designed to follow Landsat involve spatial resolution in the order of 10 to 30 m as compared to the 80 m of the Landsat Multispectral Scanner (MSS). At these higher resolutions such satellites will perform inspection functions of high importance to government agencies and which are beyond the...
New papers related to remote sensing of the earth
A. P. Colvocoresses, F.J. Doyle
1982, Open-File Report 82-237
Worldwide experience of many individuals and organizations with remote sensing data acquired from space, primarily Landsat-1, -2, and -3, has demonstrated its utility for land use classification, agricultural assessment, energy and resource exploration, and many other applications. There has been some reluctance to adopt these systems in operational programmes because...
Water-quality assessment of White River between Lake Sequoyah and Beaver Reservoir, Washington County, Arkansas
J. E. Terry, E. E. Morris, C. T. Bryant
1982, Water-Resources Investigations Report 82-4063
The Arkansas Department of Pollution Control and Ecology and U.S. Geological Survey conducted a water quality assessment be made of the White River and, that a steady-state digital model be calibrated and used as a tool for simulating changes in nutrient loading. The city of Fayetteville 's wastewater-treatment plant is...
Water-quality characteristics of Everglades National Park, 1959-77, with reference to the effects of water management
Bradley G. Waller
1982, Water-Resources Investigations Report 82-34
The U.S. Geological Survey has collected water-quality data in the Everglades National Park since 1959. Major ions, macronutrients, trace elements, and pesticides are the primary chemical groups analyzed. The period of record and frequency of sampling vary for each chemical group, with the longest record for the major ions and...
