Finite difference model for aquifer simulation in two dimensions with results of numerical experiments
Peter C. Trescott, George Francis Pinder, S. P. Larson
1976, Techniques of Water-Resources Investigations 07-C1
The model will simulate ground-water flow in an artesian aquifer, a water-table aquifer, or a combined artesian and water-table aquifer. The aquifer may be heterogeneous and anisotropic and have irregular boundaries. The source term in the flow equation may include well discharge, constant recharge, leakage from confining beds in which...
Stability of highwalls in surface coal mines, western Powder Ridge Basin, Wyoming and Montana
Fitzhugh T. Lee, William K. Smith, William Z. Savage
1976, Open-File Report 76-846
Preliminary results from the first part of a two-part investigation of the stability of highwalls in open-pit coal mines in the Fort Union Formation of the western Powder River Basin of Wyoming and Montana indicate that these highwalls are subject to time-dependent deformation. Field investigations and laboratory physical-properties tests of...
The environment of South Florida; a summary report
B. F. McPherson, G.Y. Hendrix, Howard Klein, H.M. Tyus
1976, Professional Paper 1011
Man has altered the original south Florida ecosystem to a new three-part ecosystem which incorporates an agricultural component, an urban component, and a component of the original ecosystem that is largely unchanged but still has been affected by man. These components are interrelated through the flow of energy and material....
Geologic appraisal of the petroleum potential of offshore southern California; the borderland compared to onshore coastal basins
James Carlton Taylor
1976, Circular 730
Offshore southern California is part of a much larger Pacific continental margin, and the two areas have a similar geologic history at least as far back as middle Tertiary time. Assessment of the petroleum potential of the offshore Southern California borderland is accomplished by examining the adjacent highly explored productive...
The Alaskan Mineral Resource Assessment Program: Background information to accompany folio of geologic and mineral resource maps of the Tanacross quadrangle, Alaska
Helen Laura Foster, N. R. D. Albert, D.F. Barnes, G.C. Curtin, Andrew Griscom, D.A. Singer, James G. Smith
1976, Circular 734
The Tanacross quadrangle, consisting of 17,400 km 2 (6,700 mi 2) in east-central Alaska, was investigated by an interdisciplinary research team for the purpose of assessing the mineral resource potential of the quadrangle. This report provides the background information for a folio of maps on the geology, geophysics, reconnaissance geochemistry,...
