Preliminary analysis of clay gouge from a well in the San Andreas fault zone in central California
Richard Liechti, Mark D. Zoback
1979, Open-File Report 79-861
Drilling into the San Andreas fault zone has begun in central California as part of the U.S.G.S. program of fault zone studies. The purpose of drilling into the fault zone is threefold. First, it will allow recovery of material from depth in order to determine the composition of both solid...
Relation between proposed developments of water resources and seepage from the All-American Canal, eastern Imperial Valley, California
Omar J. Loeltz, S. A. Leake
1979, Open-File Report 79-744
A two-layer digital model designed for this study indicated that sealing of the Coachella branch of the All-American Canal would cause an eventual increase in seepage from the All-American Canal of about 15,000 acre-feet annually. Sealing of both the Coachella Canal and the segment of the All-American Canal between Pilot...
Audio-magnetotelluric data log and station-location map for the Ennis Hot Springs area, Montana
Carl L. Long, R. Michael Senterfit
1979, Open-File Report 79-1308
Four days were spent collecting 20 audio-magnetotelluric (AMT) soundings in the area of the Ennis Hot Springs, Mont. (fig. 1). These soundings were made to assist in a regional evaluation of the geothermal potential of the Ennis Hot Springs area.Scalar resistivities from the data log (table 1) are indicative of...

Preconstruction and postconstruction ground-water levels, Lock and Dam 1, Red River Valley, Louisiana
A. H. Ludwig
1979, Open-File Report 79-918
Proposed construction of a series of locks and dams in the Red River in Louisiana will cause a permanent increase in average river stage. The potentiometric surface of the shallow alluvial aquifer and the water table in the fine-grained material confining the aquifer will be affected. The purpose of this...
