Hydrology of the Newberry Volcano caldera, Oregon
E.A. Sammel, R. W. Craig
1983, Water-Resources Investigations Report 83-4091
Precipitation in the Newberry Caldera is very nearly in balance with evaporation, evapotranspiration, and streamflow. Calcium, magnesium, and bicarbonate ions predominate in the more dilute ground and surface water. Thermal waters from springs and wells have concentrations of 900 milligrams per liter or more and are characterized by high concentrations...
Regional geohydrology of the northern Louisiana salt-dome basin, part IV, hydraulic characteristics of the Wilcox-Carrizo aquifer
G.N. Ryals
1983, Water-Resources Investigations Report 83-4132
The Wilcox Group of Paleocene-Eocence age and the Carrizo Sand of Eocene age compose the Wilcox-Carrizo aquifer. Results of 25 aquifer tests and permeability determinations from 43 sidewall cores show that the hydraulic characteristics of the aquifer are variable. Studies of the Carrizo showed that hydraulic conductivity increased as sand-bed...

Sulfate is the major anion in water associated with coal seams...
Meteorological, water-temperature, and discharge data for the Mattole River basin, Humboldt County, California
R.D. Noble, Alan P. Jackman
1983, Water-Resources Investigations Report 78-81
To overcome a major difficulty in the testing of the validity of river-temperature models - the lack of adequate precise synoptic data for an entire river basin - synoptic meteorologic, water-temperature, and discharge data were obtained in the Mattole River Basin in northern California during the period June 10 through...
Water resources of the Truk Islands
Otto Van der Brug
1983, Water-Resources Investigations Report 82-4082
The Truk Islands, part of the Caroline Islands in the western Pacific, consist of 19 volcanic islands and about 65 coral islets. The volcanic islands and some of the coral islets are scattered in an 820-square-mile lagoon enclosed by a 125-mile long barrier reef. Moen, although not the largest, is...
Man-induced channel adjustment in Tennessee streams
C. H. Robbins, Andrew Simon
1983, Water-Resources Investigations Report 82-4098
Channel modifications in Tennessee, particularly in the western part, have led to large-scale instabilities in the channelized rivers and may have contributed to several bridge failures. These modifications, together with land-use practices, led to downcutting, headward erosion, downstream aggradation, accelerated scour, and bank instabilities. Changes in gradient by channel straightening...
Water resources on the Pueblo of Laguna, west-central New Mexico
