Review of the hydrologic data-collection network in the St. Joseph River basin, Indiana
E. J. Crompton, J. G. Peters, R. L. Miller, J. A. Stewart, K. J. Banaszak, R. J. Shedlock
1986, Water-Resources Investigations Report 86-4157
The St. Joseph River Basin data-collection network in the St. Joseph River for streamflow, lake, ground water, and climatic stations was reviewed. The network review included only the 1700 sq mi part of the basin in Indiana. The streamflow network includes 11 continuous-record gaging stations and one partial-record station. Based...
Occurrence and availability of ground water in the Athens region, northeastern Georgia
D. B. Radtke, C.W. Cressler, H.A. Perlman, H.E. Blanchard Jr., K.W. McFadden, Rebekah Brooks
1986, Water-Resources Investigations Report 86-4075
A study was conducted to assess the occurrence and availability of groundwater in the crystalline rocks of the Piedmont area in northeastern Georgia and to determine whether groundwater is a viable alternative or supplemental source for industrial, public and private supplies. The area is underlain by a variety of metamorphic...
Multichannel seismic-reflection data collected in 1980 in the eastern Chukchi Sea
Arthur Grantz, Dennis M. Mann, Steven D. May
1986, Open-File Report 86-405
The U.S. Geological Survey (USGS) collected approximately 2,652 km of 24-channel seismic-reflection data in early September, 1980, over the continental shelf in the eastern Chukchi Sea (Fig. 1). The profiles were collected on the USGS Research Vessel S.P. Lee. The seismic energy source consisted of a tuned array of five...
Geologic and grade-tonnage information on Tertiary epithermal precious- and base-metal vein districts associated with volcanic rocks
Dan L. Mosier, W. David Menzie, Frank J. Kleinhampl
1986, Bulletin 1666
Data on grades, tonnages, and geology of selected Tertiary epithermal precious- and base-metal vein districts associated with volcanic rocks were tabulated for ease of examination and comparison of characteristics between districts. There are 215 districts listed, with a cumulative tonnage of 709 million metric tons and average grades of...
Potentiometric map of the lower Wilcox aquifer in Mississippi, fall 1982
Daphne Darden
1986, Water-Resources Investigations Report 85-4059
This potentiometric map is the second map of the lower Wilcox aquifer in a series of maps prepared by the U.S. Geological Survey in cooperation with the Mississippi Department of Natural Resources, Bureau of Land and Water Resources, delineating the potentiometric surface of the major aquifers in Mississippi. The potentiometric...
A model for the plastic flow of landslides
William Z. Savage, William K. Smith
1986, Professional Paper 1385
To further the understanding of the mechanics of landslide flow, we present a model that predicts many of the observed attributes of landslides. The model is based on an integration of the hyperbolic differential equations for stress and velocity fields in a two-dimensional, inclined, semi-infinite half-space of Coulomb plastic material...
