Ground-water models as a management tool in Florida
C. B. Hutchinson
1984, Water-Resources Investigations Report 84-4016
Highly sophisticated computer models provide powerful tools for analyzing historic data and for simulating future water levels, water movement, and water chemistry under stressed conditions throughout the ground-water system in Florida. Models that simulate the movement of heat and subsidence of land in response to aquifer pumping also have potential...
Drainage basins in St. Johns County, Florida
Donald W. Foose
1984, Water-Resources Investigations Report 84-4232
The highest point in St. Johns County, Florida is only slightly above 65 feet above sea level and drainage divides are indistinct and readily influenced by cultural features. This report delineates some 80 drainage basins (or artificial equivalents to natural basins such as the Intracoastal Waterway) within the county and...
Hydrologic maps of the Price 30 x 60-minute quadrangle, Utah
H.F. McCormack, K.L. Lindskov, Bernard J. Stolp
1984, Water-Resources Investigations Report 84-4227
Four hydrologic maps of the Price 30 x 60-minute quadrangle, Utah show that the hydrology of the area is extremely variable. Normal annual precipitation ranges from less than 8 to more than 25 inches. Corresponding ranges are less than 0.1 to more than 5 inches for average annual runoff, 0.1...
Quality of water in the alluvial aquifer, American Bottoms, East St. Louis, Illinois
David C. Voelker
1984, Water-Resources Investigations Report 84-4180
Ground-water levels in the American Bottoms regions around East St. Louis, Illinois, have risen several feet since the early 1970's. Artificial dewatering of the aquifer by increased pumping is being investigated by the U.S. Army Corps of Engineers to alleviate economic and health concerns resulting from elevated ground-water levels. A...
Estimate of self-supplied domestic water use in Oklahoma during 1980
J.D. Stoner
1984, Water-Resources Investigations Report 83-4223
Reported or measured water-use data for the domestic self-supplied user were not available for Oklahoma; therefore estimates of water use within this classification were derived. The total self-supplied population in Oklahoma during 1980 was estimated to be 343,615, which was 11.4 percent of the total 1980 State population. The rate...
Hydrologic conditions in the Chicod Creek basin, North Carolina, before and during channel modifications, 1975-81
S.A. Watkins, C.E. Simmons
1984, Water-Resources Investigations Report 84-4025
Beginning in late 1978, stream channels throughout the 60-square mile Chicod Creek basin underwent extensive modification to increase drainage efficiency and reduce flooding potential. Drainage modifications in this Coastal Plain basin, consisting primarily of channel excavation and clearing of channel blockages, were completed in December 1981. The hydrologic condition of...
Dissolved-oxygen regime of the Jordan River, Salt Lake County, Utah
D. W. Stephens
1984, Water-Resources Investigations Report 84-4056
Concentrations of dissolved oxygen in the Jordan River in Salt Lake County decrease considerably as the river flows northward. Mean concentrations of dissolved oxygen decreased from 8.1 milligrams per liter at the Jordan Narrows to 4.7 milligrams per liter at 500 North Street during April 1981 to September 1982. Coincident...
Approximate water-level changes in wells in the Chicot and Evangeline aquifers, 1977-84 and 1983-84, and measured compaction, 1973-84, in the Houston-Galveston region, Texas
Jeffrey L. Strause
1984, Open-File Report 84-140
This report, which was prepared in cooperation with the City of Houston and Harris-Galveston Coastal Subsidence District, presents data on water-level changes during 1977-84 and 1983-84 in the Chicot and Evangeline aquifers (figs. 1-4) and data on measured compaction 1973-84 (fig. 5). Water levels in about 550 wells were used to...
Investigations and research in Nevada by the Water Resources Division, U.S. Geological Survey, 1982
Terry Katzer, Otto Moosburner, W. D. Nichols
1984, Open-File Report 83-768
The Water Resources Division, U.S. Geological Survey, is charged with (1) maintaining a hydrologic network in Nevada that provides information on the status of the State 's water resources and (2) engaging in technical water-resources investigations that have a high degree of transferability. To meet these broad objectives, 26 projects...
Geohydrologic data for test well UE-25p1, Yucca Mountain area, Nye County, Nevada
R. W. Craig, K. A. Johnson
1984, Open-File Report 84-450
This report presents the following data for test well UE-25p 1 in Nye County, Nevada: drilling operations, lithology, availability of borehole geophysical logs, water levels, future availability of core analyses, water chemistry, pumping tests, borehole-flow surveys, and packer-injection tests. The well is one of a series of test wells drilled...
AQUIFEM-SALT; a finite-element model for aquifers containing a seawater interface
C.I. Voss
1984, Water-Resources Investigations Report 84-4263
Described are modifications to AQUIFEM, a finite element areal ground-water flow model for aquifer evaluation. The modified model, AQUIFEM-SALT, simulates an aquifer containing a freshwater body that freely floats on seawater. Parts of the freshwater lens may be confined above and below by less permeable units. Theory, code modifications, and...
Floods in south-central Oklahoma and north-central Texas, October 1981
Harold D. Buckner, Joanne K. Kurklin
1984, Open-File Report 84-65
Heavy rains fell over south-central Oklahoma and north-central Texas during October 11-14, 1981, causing record flooding in both States. Six lives were lost, many people were temporarily left homeless, and damages amounted to nearly $115 million. The maximum rainfall of 23 inches occurred 5 miles north of Clyde, Texas, in...
Effects of October 1981 flood on the quantity and quality of water in selected streams and reservoirs in the Brazos River basin, Texas
Frank C. Wells, Terry L. Schertz, Marvin W. Flugrath
1984, Water-Resources Investigations Report 84-4055
The storm that moved across north-central Texas during October 11-13, 1981, produced intense rainfall along a line extending from east of Abilene, Texas to Breckenridge, Texas to north of Mineral Wells, Texas. Rainfall in excess of 20 inches was recorded near Clyde. Texas and in several locations near Breckenridge, Texas. The...
