Analyses of water, core material, and elutriate samples collected near Yazoo City, Mississippi (Yazoo Headwater Project)
Harold L. Leone, Alton J. Dupuy
1978, Open-File Report 78-792
Five core-material-sampling sites were chosen by the U.S. Army Corps of Engineers to represent areas of proposed dredging activity. Four receiving-water sites also were selected to represent the water that will contact the proposed dredged material. Chemical and physical analyses were performed upon core material and native-water samples from these...
Tsunami microprocessor tide system
Harold Clark, Gary L. Heckendorn
1978, Open-File Report 78-95
A Tsunami Microprocessor Tide System was developed to replace the Advanced Tsunami Tide System. The use of microprocessor based systems will reduce manpower and hardware costs from $4,000 per advanced system to $400 per microprocessor system. In addition to the cost reduction; the capacity, capability, and flexibility of the microprocessor...
Hydrologic and geomorphic data from the Piceance Basin, Colorado, 1972-77
Donald G. Frickel
1978, Open-File Report 78-825
This report is a compilation of erosion measurements made at 121 channel sites and 45 hillslope sites during the period 1972-77 in the Piceance basin of northwestern Colorado. The data were collected as part of channel-morphology, sediment-transport, and erosion-rate studies being conducted in conjunction with development of the oil-shale resource...
A seismic refraction experiment performed in the Melones Reservoir region of the metamorphic belt, central California
James N. Murdock, John C. Roller
1978, Open-File Report 78-131
A seismic refraction experiment was conducted in the metamorphic belt of central California during May 1972. Seven charges were fired during the experiment. Three seismic refraction lines, 75 to 125 km long, were made in the belt. Also, data were gathered for regional travel-time calibrations. The experimental data are presented....
Techniques for the evaluation of surface wind data in terms of eolian sand drift
Steven G. Fryberger
1978, Open-File Report 78-405
The purpose of this report is to summarize briefly techniques presently in use by the U.S. Geological Survey (Denver) to analyze surface wind data in terms of eolian sand drift. These techniques were developed for regional analysis of surface wind directional and energy characteristics in connection with Chapter F "Dune...
Implementation plan for Bolivian Mineral Exploration Fund
Harold Kirkemo
1978, Open-File Report 79-597
Bolivia ranks second among world producers of tin and antimony, and first in bismuth production. Mineral exports in 1975 were valued at $314.2 million, nearly 60 percent of the value of all exports, and petroleum product exports totalled nearly $157 million, or 30 percent of the total. Tin accounted for...
Selected water-level records for Oklahoma, 1975-1977
Robert L. Goemaat, Dannie E. Spiser
1978, Open-File Report 78-721
A systematic program to collect water-level records in Oklahoma began in 1937. The objectives of this program are (1) to provide long-term records of water-level fluctuations in representative wells, (2) to facilitate the prediction of water-level trends and indicate future availability of ground-water supplies, and (3) to provide information for...
Documentation of potential for surface faulting related to ground-water withdrawal in Las Vegas Valley, Nevada
Thomas L. Holzer
1978, Open-File Report 78-79
Leveling data collected in Las Vegas Valley are compatible with the interpretation that ongoing land-surface displacements related to ground-water withdrawal may be precursory to fault offset of the land surface. Zones of potential faulting intersect regions of intense urban development. The degree of risk and the potential economic consequences from...
Relationship of landslides to fractures in Potomac Group deposits, Fairfax County, Virginia
William H. Langer, Stephen F. Obermeier
1978, Open-File Report 78-779
Landsliding is a common problem in eastern Fairfax County, an area underlain by Potomac Group (Lower Cretaceous) Coastal Plain deposits of silt and clay interbedded and interfingered with sand and gravel. The slides commonly are present in clay and silt that, on the basis of laboratory tests, appear to be...
Water resources along the TAPS route, Alaska, 1970-74
Joseph M. Childers, J. W. Nauman, D.R. Kernodle, P.F. Doyle
1978, Open-File Report 78-137
The U.S. Geological Survey installed 10 streamgaging and water-quality stations along the trans-Alaska pipeline route (TAPS) starting in 1970. These stations, mostly north of Fairbanks, add to the historical network of gaging stations and provide records of hydrologic conditions along the TAPS route. Selected data from 23 gaging stations along...
Fission-track dating of the Climax and Gold Meadows stocks, Nye County, Nevada
Charles W. Naeser, Florian Maldonado
1978, Open-File Report 78-419
Fission-track ages indicate an age of 101 m.y. for the Climax stock and a minimum age of 93.6 m.y. for the Gold Meadows stock, both at the Nevada Test Site, Nye County, Nevada. Younger fission-track ages for apatite concentrates suggest that the stocks have been within 4 km of the...
