Channel erosion surveys along the TAPS route, Alaska, 1977
Robert M. Loeffler, Joseph M. Childers
1977, Open-File Report 78-611
Channel surveys were made along the trans-Alaska pipeline system (TAPS) route during 1977 at the same 28 sites that were studied in 1976. In addition, a new site at pipeline mile 22 near Deadhorse (alignment No 134) along the Sagavanirktok River was put under surveillance. Except for changes wrought by...
Background studies for appraising subsidence in the Texas Gulf Coast region
B. E. Lofgren
1977, Open-File Report 77-412
Significant ground movement has accompanied the extraction of large quantities of fluids from the subsurface at many localities. The possibility of both horizontal and vertical ground movement--subsidence, fissuring, growth faulting--in the Gulf Coast region, caused by the withdrawal of large volumes of deep formation fluids, is of major concern.Although widespread...
Summary of the geology and physical properties of the Climax Stock, Nevada Test Site
Florian Maldonado
1977, Open-File Report 77-356
The Climax stock is a composite stock of Cretaceous age, composed of quartz monzonite and granodiorite, which intrudes sedimentary rocks of Paleozoic and Precambrian age. Tertiary rocks consisting of tuff, welded tuff, and breccia overlie the stock and sedimentary rocks. Hydrothermal alteration of the granodiorite and quartz monzonite is found mainly...
Chemical, isotopic, and gas compositions of selected thermal springs in Arizona, New Mexico, and Utah
Robert H. Mariner, T. S. Presser, William C. Evans
1977, Open-File Report 77-654
Twenty-seven thermal springs in Arizona, New Mexico, and Utah were sampled for detailed chemical and isotopic analysis. The springs issue sodium chloride, sodium bicarbonate, or sodium mixed-anion waters of near neutral (6.2) to alkaline (9.2) pH. High concentrations of fluoride, more than 8 milligrams per liter, occur in Arizona in...
Water-level records for Adams, Larimer, Logan, Morgan, Sedgwick, Washington, and Weld Counties, Colorado, 1973-77
Thomas J. Major, Kenneth D. Vaught
1977, Open-File Report 77-461
Water levels measured during March 1977 in 350 wells tapping alluvial aquifers in Adams, Larimer, Logan, Morgan, Sedgwick, Washington, and Weld Counties, Colo., are included in this report. Water-level records for the 4 preceding years also are included to serve as references illustrating declining or rising water levels.Water-level measurements made...
Seepage tests on No Name Creek, Colville Indian Reservation, Washington, May 12-13, 1977
Robert D. MacNish
1977, Open-File Report 77-618
To gain information for a water-management situation, a seepage test was performed on May 12-13, 1977, on a reach of No Name Creek on the Colville Indian Reservation in north-central Washington. On May 13, injection of a concentrated brine at the head of the test reach permitted chloride-concentration data to...
Hot springs of the central Sierra Nevada, California
Robert H. Mariner, T. S. Presser, William C. Evans
1977, Open-File Report 77-559
Thermal springs of the central Sierra Nevada issue dilute to slightly saline sodium chloride, sodium bicarbonate, or sodium mixed-anion waters ranging in pH from 6.4 to 9.3. The solubility of chalcedony appears to control the silica concentration in most of the spring waters. Fales Hot Springs may be associated with...
Analyses of water, core material, and elutriate samples collected near Galliano, Louisiana: Larose to Golden Meadow, Louisiana, Hurricane Protection Project
Harold L. Leone
1977, Open-File Report 77-576
Seven core-material-sampling sites were chosen by the U.S. Army Corps of Engineers as possible borrow areas for fill material to be used in levee construction near Galliano La. Four receiving-water sites also were selected to represent the water that will contact the proposed levees. Analyses of selected nutrients, metals, pesticides,...
Drainage areas of the Guyandotte River basin, West Virginia
M.V. Mathes
1977, Open-File Report 77-801
This report, prepared in cooperation with the West Virginia Office of Federal-State Relations (now the Office of Economic and Community Development), lists in tabular form 435 drainage areas for basins within the Guyandotte River basin of West Virginia. Drainage areas are compiled for sites at the mouths of all streams...
Preliminary analysis of lineaments and engineering properties of bedrock, Penobscot Bay area, Maine
Fitzhugh T. Lee, Dennis W. O’Leary, Sharon F. Diehl
1977, Open-File Report 77-886
A remote sensing study of coastal and near coastal Maine was undertaken to identify bedrock features of possible importance to construction. Major lineaments were identified that separate the region into four distinct terrains. Within each terrain, smaller lineaments and other physiographic features show distinctive and consistent patterns, reflecting similarities in...
Ground water in the Lajas Valley, Puerto Rico
Henry R. Anderson
1977, Water-Resources Investigations Report 76-68
Lajas Valley is plagued with salinity and waterlogging problems of the soils. Use of brackish (500 milligrams per liter) ground water for irrigation compounded the problem until an irrigation-drainage system was constructed in 1955. Lajas Valley is an alluvium-filled trough between volcanic and limestone highlands. The alluvium, mostly clay and...
Ground-water resources of the Riviera Beach area, Palm Beach County, Florida
L. F. Land
1977, Water-Resources Investigations Report 77-47
The principal source of freshwater that has been developed in the Riviera Beach area is the so-called shallow aquifer, which is composed of sand, shells, sandstone, limestone, marl, and occasionally clay strata. Often a stratum contains mixtures of two or more of these materials and occasionally they are cemented. The...
