Estimating the gas and dye quantities for modified tracer technique measurements of stream reaeration coefficients
R. E. Rathbun
1979, Water-Resources Investigations Report 79-27
Measuring the reaeration coefficient of a stream with a modified tracer technique has been accomplished by injecting either ethylene or ethylene and propane together and a rhodamine-WT dye solution into the stream. The movement of the tracers through the stream reach after injection is described by a one-dimensional diffusion equation....
Map showing ground-water conditions in the Virgin River, Grand Wash, and Shivwits areas, Mohave County, Arizona, 1976
G. W. Levings, C. D. Farrar
1979, Water-Resources Investigations Report 79-57
The Virgin River, Grand Wash, and Shivwits areas include about 3 ,250 square miles in northwestern Arizona. Ground water is obtained mainly from the alluvium, conglomerate, and basalt; however, several other formations yield small amounts of water to some wells. In the Virgin River area, most wells are less than...
Program and plans of the U.S. Geological Survey for producing information needed in National Seismic hazards and risk assessment, fiscal years 1980-84
Walter W. Hays
1979, Circular 816
In accordance with the provisions of the Earthquake Hazards Reduction Act of 1977 (Public Law 95-124), the U.S. Geological Survey has developed comprehensive plans for producing information needed to assess seismic hazards and risk on a national scale in fiscal years 1980-84. These plans are based on a review of...
Chemical and biological quality of selected lakes in Ohio, 1976 and 1977
Robert L. Tobin, John D. Youger
1979, Water-Resources Investigations Report 78-109
Twenty-eight Ohio lakes (14 per year) were sampled by the U.S. Geological Survey and Ohio Environmental Protection Agency for the water-quality characteristics during the spring and summer of 1976 and 1977. Data items included: profiles of temperature, dissolved oxygen, pH, and specific conductance; physical, biological, nutrient, and organic characteristics; major...
Possible uranium mineralization, Mineral Mountains, Utah
W. Roger Miller, John B. McHugh, Walter H. Ficklin
1979, Open-File Report 79-1354
The Mineral Mountains block in west-central Utah is a horst whose core stands structurally high relative to all nearby basin-and-range fault blocks. Rocks of the Mineral Mountains range from Precambrian to Quaternary in age, but mostly consist of Tertiary granitic rocks. The range lies with the Wah Wah-Tusher mineral belt....
Surface subsidence and collapse in relation to extraction of salt and other soluble evaporites
John R. Ege
1979, Open-File Report 79-1666
Extraction of soluble minerals, whether by natural or man-induced processes, can result in localized land-surface subsidence and more rarely sinkhole formation. One process cited by many investigators is that uncontrolled dissolving of salt or other soluble evaporites can create or enlarge underground cavities, thereby increasing the span of the unsupported...
Introduction to monitoring dynamic environmental phenomena of the world using satellite data collection systems, 1978
William Douglas Carter, Richard W. Paulson
1979, Circular 803
The rapid development of satellite technology, especially in the area of radio transmission and imaging systems, makes it possible to monitor dynamic surface phenomena of the Earth in considerable detail. The monitoring systems that have been developed are compatible with standard monitoring systems such as snow, stream, and rain gages;...
Water resources data for Washington, water year 1978, Vol. 2 - Eastern Washington
Water Resources Division, U.S. Geological Survey
1979, Water Data Report WA-78-2
Water resources data for the 1978 water year for Washington consist of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels and water quality of ground-water wells. This volume contains records for water discharge at 248 gaging stations;...
Maps showing saturated thickness, January 1979, and percentage decrease in saturated thickness, 1950-79, of unconsolidated aquifer, west-central Kansas
Marilyn E. Pabst
1979, Open-File Report 79-1340
The principal water-yielding formation (unconsolidated aquifer) supplying water to wells in west-central Kansas is comprised of the Ogallala Formation and undifferentiated Pleistocene deposits. About 1,860 square miles of the area are underlain by sufficient saturated material to supply groundwater for irrigation. Saturated thickness in the area ranges from less than...
