Water and streambed-material data, Eagle Creek watershed, Indiana, August 1980-December 1982
David J. Wangsness
1983, Open-File Report 83-215
Water quality studies within the Eagle Creek watershed, Indiana, were done by the U.S. Geological Survey in August 1980, October 1982, and December 1982 in cooperation with the city of Indianapolis, Department of Public Works. Streambed-material and water samples were collected from Finley and Eagle Creeks at various flow rates...
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...
Alteration and vein mineralization, Schwartzwalder uranium deposit, Front Range, Colorado
Alan R. Wallace
1983, Open-File Report 83-417
The Schwartzwalder uranium deposit, in the Front Range west of Denver, Colorado, is the largest vein-type uranium deposit in the United States. The deposit is situated in a steeply dipping fault system that cuts Proterozoic metamorphic rocks. The host rocks represent a submarine volcanic system with associated chert and iron-...
Preliminary stage-discharge relations for Tombigbee River at Gainesville Dam, near Gainesville, Alabama
G. H. Nelson, C. O. Ming
1983, Open-File Report 83-942
The construction of Gainesville Dam and other related channel alterations, completed in 1979, has resulted in changes to the stage-discharge relations in the vicinity. The lack of current-meter measurements, coupled with backwater conditions, makes definition of a single stage-discharge relation impossible. However, limit curves can be defined that would encompass...
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...
Water and streambed-material data, Eagle Creek watershed, Indiana, August 1980, October and December 1982, and April 1983; updating of U.S. Geological Survey Open-file report 83-215
David J. Wangsness
1983, Open-File Report 83-532
Water-quality surveys within the Eagle Creek watershed were done by the U.S. Geological Survey in August 1980, October and December 1982 and April 1983 in cooperation with the city of Indianapolis, Department of Public Works. Streambed-material and water samples were collected from Finley and Eagle Creek and was analyzed for...
Water resources data Iowa, water year 1982
I.L. Burmeister, V.L. Spiers, P. J. Soenksen, W.J. Matthes
1983, Water Data Report IA-82-1
Water resources data for the 1982 water year for Iowa consists of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels in wells. This report contains discharge records for 116 gaging stations; stage and contents for 7 lakes and reservoirs; water...
Water resources data, Maine, water year 1982
R.A. Morrill, C.R. Haskell, G.C. Prescott, T. J. Maloney
1983, Water Data Report ME-82-1
Water resources data for the 1982 water year for Maine consist of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and water levels and water quality of wells. This report contains discharge records for 70 gaging stations; stage only for 1 gaging...
Geophysical and geologic studies in southern Mecklenburg County and vicinity, North Carolina and South Carolina
Frederick A. Wilson
1983, Open-File Report 83-93
Geophysical methods consisting of gravity, aeromagnetics and aeroradioactivity have been applied to part of the Charlotte and Carolina slate belts in southern Mecklenburg County and vicinity to help interpret geology, lithology and structure. High aeroradioactivity is associated with potassium-rich granitic plutons, muscovite-rich gneisses, schists, and metavolcanic rocks; positive gravity and...
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...
