Geomorphological interpretations of late Quaternary terraces in western Tennessee and their regional tectonic implications
Roger T. Saucier
David P. Russ, Anthony J. Crone, editor(s)
1987, Professional Paper 1336-A
By use of large-scale topographic maps and traditional techniques of geomorphology. a series of stream terraces was identified and delineated on the Obion, Forked Deer, Hatchie, Loosahatchie, and Wolf Rivers in western Tennessee. From lowest and youngest to highest and oldest, they are designated the Finley, Hatchie, Humboldt, and Henderson terraces. The...
Effect of reduced industrial pumpage on the migration of dissolved nitrogen in an outwash aquifer at Olean, Cattaraugus County, New York
M. P. Bergeron
1987, Water-Resources Investigations Report 85-4082
A quasi-three-dimensional digital groundwater flow model of a shallow outwash aquifer system at Olean, New York, was developed to study the effects of several pumping alternatives on groundwater flow and stream seepage. Nitrogen compounds have contaminated the aquifer in an industrial park in North Olean. Pumping from seven industrial production...
Map projections: A working manual
John P. Snyder
1987, Professional Paper 1395
After decades of using only one map projection, the Polyconic, for its mapping program, the U.S. Geological Survey (USGS) now uses several of the more common projections for its published maps. For larger scale maps, including topographic quadrangles and the State Base Map Series, conformal projections such as the Transverse...
Habitat Suitability Index Models: Mallard (winter habitat, Lower Mississippi Valley)
Arthur W. Allen
1987, FWS/OBS 82/10.132
A review and synthesis of existing information were used to develop a Habitat Suitability Index (HSI) model for the mallard (Anas platyrhynchos). The model consolidates habitat use information into a framework appropriate for field application, and is scaled to produce an index between 0.0 (unsuitable habitat) to 1.0 (optimum habitat)....
Habitat Suitability Index Models: Flathead catfish
Lawrence A. Lee, James W. Terrell
1987, FWS/OBS 82/10.152
A review and synthesis of existing information were used to develop a Habitat Suitability Index (HSI) model for the flathead catfish (Pylodictis olivaris). The model consolidates habitat use information into a framework appropriate for field application, and is scaled to produce an index between 0.0 (unsuitable habitat) to 1.0 (optimum...
Geologic map of the Three Sisters Wilderness, Deschutes, Lane, and Linn counties, Oregon
E. M. Taylor, N. S. MacLeod, D. R. Sherrod, G. W. Walker
1987, Miscellaneous Field Studies Map 1952
The Wilderness Act (Public Law 88-577, September 3, 1964) and related acts require the U.S. Geological Survey and the U.S. Bureau of Mines to survey certain areas on Federal lands to determine the mineral values, if any, that may be present. Results must be made available to the public and...
