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...
Notes on the availability of mid-Atlantic multichannel seismic reflection profiles 11 and 12-A, -B, -C, and -D
John Stevens Schlee
1978, Open-File Report 78-474
Available are two multichannel profiles collected by Digicon Geophysical Corporation in 1975 using a 48-channel streamer (3600 m long). and a 27.9 cu. liter air gun array. They were processed in Denver on the Phoenix "I" by William C. Patterson. The processing included demultiplexing and resampling, geometry and common-depth-point definition,...
Flood investigations in Nevada through 1977 water year
Otto Moosburner
1978, Open-File Report 78-610
Maximum annual discharges, gage heights, and probable flood dates for 127 sites are compiled for Nevada streams. Data have been collected in cooperation with the Nevada Department of Highways at most of the sites (108).Also included in the report are the peak discharges, gage heights, and flood dates for the...
A literature review of interaction of oxidized uranium species and uranium complexes with soluble organic matter
Joan K. Jennings, J.S. Leventhal
1978, Open-File Report 78-179
Organic material is commonly found associated with uranium ores in sandstone-type deposits. This review of the literature summarizes the classes and separations of naturally occurring organic material but the emphasis is on soluble organic species. The main class of materials of interest is humic substances which are high-molecular-weight complex molecules...
Drilling, construction, and testing of water-supply wells 21 and 22, White Sands Missle Range, Dona Ana County, New Mexico
Clyde A. Wilson, R.R. White, R. G. Roybal, J.L. Gonzales
1978, Open-File Report 78-172
During the spring and summer of 1976, two municipal-supply wells (designated as well 21 and well 22 - 2,000 feet apart) were drilled at the Post Headquarters area of White Sands Missile Range, New Mexico. The design specifications for both wells called for 24-inch diameter surface casing cemented in place...
Planning report for the southeastern limestone regional aquifer system analysis
Richard H. Johnston
1978, Open-File Report 78-516
The southeastern limestone aquifer system is one of the major sources of ground water in the United States. Over 3 billion gallons of water are pumped daily making the aquifer the principal source of municipal, industrial, and agricultural water supply in large parts of Florida and Georgia and to a...
Local magnetic field measurements, fault creep observations and local earthquakes on the San Andreas fault
M.J.S. Johnston, B.E. Smith, Robert Martin Mueller
1978, Open-File Report 78-809
Simultaneous records of local variations in magnetic field, fault creep and the occurrence times of local earthquakes have been obtained for the period early 1974 through mid-1977 along the San Andreas fault between the most southern extent of the 1906 earthquake fault break and the most northern extent of the...
Application of digital profile modeling techniques to ground-water solute transport at Barstow, California
Stanley G. Robson
1978, Water Supply Paper 2050
This study investigated the use of a two-dimensional profile-oriented water-quality model for the simulation of head and water-quality changes through the saturated thickness of an aquifer. The profile model is able to simulate confined or unconfined aquifers with nonhomogeneous anisotropic hydraulic conductivity, nonhomogeneous specific storage and porosity, and nonuniform saturated...
Water-resources appraisal of the Wet Mountain Valley, in parts of Custer and Fremont counties, Colorado
C.J. Londquist, R.K. Livingston
1978, Water-Resources Investigations Report 78-1
The Wet Mountain Valley is an intermontane trough filled to a depth of at least 6,700 feet with unconsolidated deposits. Ground water occurs under both artesian and water-table conditions within the basin-fill aquifer and ground-water moverment is toward Grape and Texas Creeks. The depth to the water table is less...
Water resources data for Florida, water year 1977; Volume 2B, southern Florida, ground water
Water Resources Division, U.S. Geological Survey
1978, Water Data Report FL-77-2B
Water resources data for the 1977 water year in Florida consist of discharge records for 271 streams, stage-only records for 223 streams, elevations for 228 lakes, 66 crest-stage partial records and water level measurements for 828 wells. Water quality data for approximately 680 surface sites and 930 wells are included.The...
