Evaluation of availability of water from drift aquifers near the Pomme de Terre and Chippewa rivers, western Minnesota
G. N. Delin
1987, Water-Resources Investigations Report 86-4321
Ground-water flow in the confined- and unconfined-drift aquifers near Appleton and Benson, Minnesota, was simulated with a three-dimensional finite-difference ground-water-flow model. Model results indicate that 98 percent of the total inflow to the modeled area is from precipitation. Of the total outflow, 38 percent is ground-water discharge to the Pom...

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...

Petrology and sedimentology of the Horlick Formation (Lower Devonian), Ohio Range, Transantarctic Mountains
Lucy McCartan, Margaret A. Bradshaw
1987, Bulletin 1780
The Horlick Formation of Early Devonian age is as thick as 50 m and consists of subhorizontal, interbedded subarkosic sandstone and chloritic shale and mudstone. The Horlick overlies an erosion surface cut into Ordovician granitic rocks and is, in turn, overlain by Carboniferous and Permian glacial and periglacial deposits. Textures,...
Estimation of the recharge area contributing water to a pumped well in a glacial-drift, river-valley aquifer
D. J. Morrissey
1987, Open-File Report 86-543
The highly permeable, unconfined, glacial drift aquifers that occupy most New England river valleys constitute the principal source of drinking water for many communities that obtain part or all of their public water supply from groundwater. Analytical , two-dimensional numerical and three-dimensional numerical models were used to delineate contributing areas...
Mineral resources of the Fort Piute Wilderness Study Area, San Bernardino County, California

1987, Water-Resources Investigations Report 87-4143
At an extensometer site near Eloy, Arizona, 1.09 m of land subsidence caused by groundwater withdrawal were measured by leveling in 1965-83. The extensometer, which partially penetrates the compressible sediments, recorded 0.82 m of compaction during the same period. By use of a one-dimensional model, cumulative daily compaction values were...
