Seismic properties investigation of the Springer Ranch landslide, Powder River basin, Wyoming
C.H. Miller, A.L. Ramirez, T.G. Bullard
1980, Professional Paper 1170-C
A recent and rapid increase since the mid-1970's in commercial and residential development in the Powder River Basin, Wyoming and Montana, is caused by exploitation of vast coal and other resources in the basin. One geologic hazard to such development is landsliding. A landslide sufficiently representative of others in the...

Robert J. Shedlock
1980, Water-Resources Investigations Report 80-65
A plume of saline water at the base of the glacial outwash aquifer near Vincennes, Indiana, has been drawn into the municipal well field. However, the average chloride concentration of the municipal water, 30 + or - 5 milligrams per liter, did not change significantly from 1976 to 1979. The...
The influences of land use and land cover on climate; an analysis of the Washington-Baltimore area that couples remote sensing with numerical simulation
R.W. Pease, C.B. Jenner, J.E. Lewis Jr.
1980, Professional Paper 1099-A
The Sun drives the atmospheric heat engine by warming the terrestrial surface which in turn warms the atmosphere above. Climate, therefore, is significantly controlled by complex interaction of energy flows near and at the terrestrial surface. When man alters this delicate energy balance by his use of the land, he...

Use of geophysical logs to estimate water-quality trends in carbonate aquifers
Lawrence Mead MacCary
1980, Water-Resources Investigations Report 80-57
The water quality in carbonate aquifers can be determined by analysis of resistivity and porosity logs. When supporting data from water analyses are available, the value of the cementation exponent m can be determined more precisely. Data for this study were taken from logs of oil-test wells, Amstrat sample studies,...
