Geochemical exploration for uranium in playas
D. L. Leach, K.P. Puchlik, R.K. Glanzman
1980, Journal of Geochemical Exploration (13) 251-283
Playas and closed-basin lakes represent unique geochemical environments for the entrapment and concentration of mobile chemical elements. For this reason, playas may be considered as potentially favorable areas for the accumulation of uranium. We investigated playa sediments to determine their value as possible sample media for determining the presence...
The mass balance approach: application to interpreting the chemical evolution of hydrologic systems
Niel Plummer, W. Back
1980, American Journal of Science (280) 130-142
Mass balance calculations are applied to observed chemical and isotopic data of three natural water systems involving carbonate reactions in order to define mineral stoichiometry of reactants and products, relative rates of reactions, and mass transfer. One study evaluates reactions in a lagoon on the east coast of the Yucatan...
Satellite remote sensing of water turbidity
Gerald K. Moore
1980, Hydrological Sciences Bulletin (25) 407-421
Remote sensing instruments obtain an optical measure of water colour and turbidity. Colour increases the absorption of light in water and decreases the remotely sensed signal; turbidity increases the backscatter of light. For low concentrations of suspended materials, spectral reflectance is determined mostly by the absorptance characteristics of water; for...
Remote sensing of snow and ice
M. F. Meier
1980, Hydrological Sciences Bulletin (25) 307-330
Monitoring of snow and ice on the Earth's surface will require increasing use of satellite remote sensing techniques. These techniques are evolving rapidly. Active and passive sensors operating in the visible, near infrared, thermal infrared, and microwave wavelengths are described in regard to general applications and in regard to specific...

1980, Journal of Hydrology (45) 1-19
Mixing models and evaluation of SiO2 contents of warm-water manifestations in the Jordan—Dead Sea Rift Valley indicate that these waters are fed by aquifers with estimated temperatures of up to 68°C. These calculations and Na/K ratios, concentrations of Na, K and Ca, concentrations of atmospheric Ne, Ar, Kr and Xe;...

Walter R. Meyer, Jerry E. Carr
1979, Limited Printing Report 103
This report documents the construction and calibration of a digital model for the simulation of hydrologic conditions in the Chicot and Evangeline aquifers in the Houston area of southeastern Texas. The model is a five-layer finite-difference model, with a grid pattern of 63 x 67 nodes representing an area of...
Better utilization of ground water in the Piedmont and mountain region of the southeast
Ralph C. Heath
1979, Conference Paper, Water conservation and alternative water supplies: proceedings of a southeast regional conference
The development of water supplies for domestic consumption, and for those commercial and industrial uses requiring relatively pure water, has followed a pattern in the Piedmont and mountain areas of the southeast similar to that in most other humid areas. The first settlers utilized seepage springs on hillsides. Such springs...
United States Geological Survey Yearbook, fiscal year 1978
Water Resources Division, U.S. Geological Survey
1979, Report
Fiscal year 1978 saw the U.S. Geological Survey continuing to perform its basic historical missions of collecting, analyzing, and disseminating information about the Earth, its processes, and its water and mineral resources. Classifying Federal lands and supervising lessee mineral extraction operations on those lands were also major Survey concerns during...
Hydrologic and water-quality appraisal of southeast Nassau County, Long Island, New York

Hydrologic data, 1974-77, Stovepipe Wells Hotel area, Death Valley National Monument, Inyo County, California
Charles Edwin Lamb, D.J. Downing
1979, Open-File Report 79-203
Ground-water levels in most wells did not change significantly from 1974 to 1977 in the Stovepipe Wells Hotel area. The average water-level decline was less than 0.10 foot between August 1974 and August 1977 in 10 observation wells. Water-level contours show a depression centered on the two pumping wells, but...
Bedrock aquifers in the lower Dirty Devil River Basin area, Utah, with special emphasis on the Navajo sandstone
J. W. Hood, T. W. Danielson
1979, Open-File Report 79-1163
The lower Dirty Devil River basin area in southeastern Utah has an area of about 4,300 square miles (11,1140 square kilometers) and ranges in altitude from about 3,700 to more than 11,000 feet (1,130 to 3,350 meters) above mean sea level. Precipitation, the main source of water in the area,...
Summary appraisals of the nation's ground-water resources – Lower Mississippi region
J. E. Terry, R.L. Hosman, C. T. Bryant
1979, Professional Paper 813-N
The Lower Mississippi Region comprises an area of 102,400 square miles (265,200 square kilometers). Almost all this area is in the physiographic province known as the Gulf Coastal Plain. Three small areas on the northwest boundary of the region are in the Interior Highlands. The Lower Mississippi Region has an abundance...

Brevard County is an area of some 1,300 square miles located on the east coast of central Florida. The Cape Canaveral quadrangle, in central Brevard, includes part of the Merritt Island National Wildlife Refuge, John F. Kennedy Space Center (NASA), and Cape Canaveral Air Force Station. The eastern part of...

Map showing occurrences of spring-deposited travertine in the conterminous Western United States
J. H. Feth, Ivan Barnes
1979, Water-Resources Investigations Report 79-35
Extinct travertine terraces occur hundreds of meters above present levels of spring activity and have potentials for interpretation of ancient hydrologic systems, rates of downcutting, or rates of tectonic uplift that remain virtually unexploited. The abundance and size of extinct travertine deposits suggest that in many places, such as pinnacles...

Environmental features, general hydrology, and external sources of nutrients affecting Wilderness Lake, King County, Washington
N. P. Dion
1979, Water-Resources Investigations Report 79-63
A water budget prepared for Wilderness Lake, a candidate for lake-quality restoration, indicates that of the 530 acre-feet of water that enters the lake each year, 170 acre-feet is from precipitation and 360 acre-feet is from groundwater inflow. An equal amount leaves the lake, and of this, 380 acre-feet is...
