Predictive simulation of alternatives for managing the water resources of North Fork Solomon River Valley between Kirwin Dam and Waconda Lake, north-central Kansas
R.D. Burnett
1984, Water-Resources Investigations Report 84-4249
Since 1974 water levels in the alluvial aquifer of the North Fork Solomon River Valley in north-central Kansas have decreased due to increases in ground-water pumpage, decreases in availability of surface water for irrigation, and below-average precipitation. A finite-element model was developed in cooperation with the U.S. Bureau of Reclamation...
Glastonbury Gneiss and mantling rocks (a modified Oliverian dome) in south-central Massachusetts and north-central Connecticut: Geochemistry, petrogenesis, and isotopic age
G. W. Leo, R. E. Zartman, D. G. Brookins
1984, Professional Paper 1295
The Glastonbury dome is a long, narrow structure trending approximately 70 km north-northeast through Connecticut and Massachusetts along the west side of the Bronson Hill anticlinorium. Structurally and stratigraphically the dome is analogous to the Oliverian domes of New Hampshire. It is cored by Glastonbury Gneiss and is mantled by...
Igneous activity and related ore deposits in the western and southern Tushar Mountains, Marysvale volcanic field, west-central Utah
Thomas A. Steven, editor(s)
1984, Professional Paper 1299-A,B
PART A: Igneous activity in the Marysvale volcanic field of western Utah can be separated into many episodes of extrusion, intrusion, and hydrothermal activity. The rocks of the western Tushar Mountains, near the western part of the volcanic field, include intermediate-composition, calc-alkalic volcanic rocks erupted from scattered volcanoes in Oligocene...
Statistical relations among earthquake magnitude, surface rupture length, and surface fault displacement
M. G. Bonilla, R. K. Mark, J. J. Lienkaemper
1984, Open-File Report 84-256
In order to refine correlations of surface-wave magnitude, fault rupture length at the ground surface, and fault displacement at the surface by including the uncertainties in these variables, the existing data were critically reviewed and a new data base was compiled. Earthquake magnitudes were redetermined as necessary to make them...
Leperditicopid ostracodes from Ordovician rocks of Kentucky and nearby states and characteristic features of the order Leperditicopida
J.M. Berdan
1984, Professional Paper 1066-J
Leperditicopid ostracodes from the Ordovician formations of Kentucky occur in micritic to fine-grained carbonate rocks believed to represent shallow-water facies. They are found at widely separated horizons in the Middle Ordovician High Bridge Group, the Middle and Upper Ordovician Lexington Limestone, and the Upper Ordovician Ashlock, Bull Fork, and Drakes...
Determination of reaeration coefficients for Ohio streams
Janet Hren
1984, Water-Resources Investigations Report 84-4139
The hydrocarbon-gas tracer technique was used to determine reaeration coefficients on 30 reaches of Ohio streams. The studies were done from September 1979 through August 1982 to determine the reaeration coefficients for the individual reaches and to develop general equation that could be used to estimate the coefficients. Multiple linear...
Simulated effects of proposed reservoir-development alternatives on streamflow quantity in the White River, Colorado and Utah
Gerhard Kuhn, S. R. Ellis
1984, Water-Resources Investigations Report 84-4297
Numerous reservoirs have been proposed for the White River basin in Colorado and Utah, primarily to provide water for oil-shale development. A multireservoir-flow model was used to simulate the effects of streamflow withdrawal at four of the proposed reservoirs using historical streamflow data from the 1932-81 water years. The proposed...
Geohydrologic data for test well USW G-4, Yucca Mountain area, Nye County, Nevada
C.B. Bentley
1984, Open-File Report 84-63
Data are presented on drilling operations, lithology, borehole geophysics, hydrologic monitoring, core analysis, water chemistry, pumping tests, and packer-injection tests for test well USW G-4. The well is one of a series of test wells drilled in and near the southwestern part of the Nevada Test Site, Nye County, Nevada,...
A statistical approach to evaluate the relation of coal mining, land reclamation, and surface-water quality in Ohio
Janet Hren, K. S. Wilson, D.R. Helsel
1984, Water-Resources Investigations Report 84-4117
Base-flow data from 779 sites in Ohio 's coal region were analyzed statistically to relate land use to selected water-quality characteristics. Sites were classified into five categories: unmined (100 percent unmined land), abandoned (50 percent or more abandoned surface mines), reclaimed (50 percent or more reclaimed surface mines), deep-mined (50...
Hydrogeology of the Verna well-field area and management alternatives for improving yield and quality of water, Sarasota County, Florida
C. B. Hutchinson
1984, Water-Resources Investigations Report 84-4006
About 8 million gallons of water are pumped daily from the 3-square-mile Verna well field to supply the city of Sarasota. Pumping has resulted in water-level declines and changes in water quality. Drawdowns of at least 30 feet have occurred in the producing zone at the well-field boundaries. Sulfate concentrations...
