Summaries of technical reports, Volume XV
Muriel L. Jacobson (compiler), Thelma R. Rodriguez, Wanda H. Seiders
1983, Open-File Report 83-90
The research results described in the following summaries were submitted by the investigators on November 15, 1982 and cover the 6-month period from April 1, 1982 through September 30, 1982. These reports include both work performed under contracts administered by the Geological Survey and work by members of the Geological Survey. The report summaries...
Numerical simulation of ground-water flow in lower Satus Creek Basin, Yakima Indian Reservation, Washington
E. A. Prych
1983, Water-Resources Investigations Report 82-4065
A multilayer numerical model of steady-state ground-water flow in lower Satus Creek basin was constructed, calibrated using time-averaged data, and used to estimate the long-term effects of proposed irrigation-water management plans on ground-water levels in the area. Model computations showed that irrigation of new lands in the Satus uplands would...
Geophysical investigations of the Umm ar Rummf copper prospect, Al Qunfudhah Quadrangle, Kingdom of Saudi Arabia
Hamdy S. Sadek, H. Richard Blank
1983, Open-File Report 83-298
The Umm ar Rummf copper prospect, located about 30 km east of Al Qunfudhah, Kingdom of Saudi Arabia, consists of zones of malachite disseminations and fracture fillings in outcrops of north-trending impure quartzite of the Bahah group. Systematic Crone electromagnetic and self-potential surveys indicate that weakly conductive tabular bodies having...
Cost-effectiveness of the stream-gaging program in Maine
Richard A. Fontaine, M. E. Moss, J.A. Smath, W. O. Thomas
1983, Open-File Report 83-261
Data uses and funding sources were identified for the 51 continuous stream gages currently being operated in Maine. Three stream-gages were identified as having insufficient reason to continue their operation. Operation of these stations were identified as having uses specific only to short-term studies; it is recommended that these stations...
Instrumentation used for hydraulic testing of potential water-bearing formations at the Waste Isolation Pilot Plant site in southeastern New Mexico
J.A. Basler
1983, Open-File Report 83-144
Requirements for testing hydrologic test wells at the proposed Waste Isolation Pilot Plant near Carlsbad, New Mexico, necessitated the use of inflatable formation packers and pressure transducers. Observations during drilling and initial development indicated small formation yields which would require considerable test times by conventional open-casing methods. A pressure-monitoring system...
Preliminary lithologic, geotechnical, and geophysical data from drill hole CW-81-2, Chuitna West coal field, Cook Inlet region, Alaska
Jack K. Odum, Cynthia A. Gardner, Lynn A. Yehle, Henry R. Schmoll, Larry L. Dearborn
1983, Open-File Report 83-78
The drilling and logging activity described in this report was undertaken in July 1981, as part of the Energy Lands program of the U.S. Geological Survey. The general objectives of the project of which this work is a part are to provide an understanding of the nature, location, and extent...
Water resources of the Fort Union coal region, east-central Montana
S.E. Slagle
1983, Water-Resources Investigations Report 83-4151
The shallow ground-water system in the Fort Union coal region overlies the Upper Cretaceous Bearpaw Shale. It includes the Upper Cretaceous Fox Hills Sandstone and the overlying Hell Creek Formation, Paleocene Fort Union Formation, and Pleistocene and Holocene glacial deposits, terrace deposits, and alluvium. Two general flow patterns are present...
