Ground-water resources of St. Johns County, Florida
R. M. Spechler, P. S. Hampson
1984, Water-Resources Investigations Report 83-4187
The primary sources of water in St. Johns County are the surficial and Floridan aquifers. The surficial aquifer is the principal source of public and rural water supplies in most of the county. The Floridan aquifer serves as the major source of water for irrigation. In much of the county,...
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...
Compilation of selected hydrologic data from the MX missile-siting investigation, east-central Nevada and western Utah
Robin L. Bunch, James R. Harrill
1984, Open-File Report 84-702
Construction, water-level, and water-quality data for wells and site-description, discharge, and water-quality data for springs and streams in 37 hydrographic areas in Nevada and Utah are presented in this report. These data are grouped in tables, by area. Additional tables contain a summary of data and aquifer-test results for wells...
The principle of superposition and its application in ground-water hydraulics
T. E. Reilly, O.L. Franke, G.D. Bennett
1984, Open-File Report 84-459
The principle of superposition, a powerful methematical technique for analyzing certain types of complex problems in many areas of science and technology, has important application in ground-water hydraulics and modeling of ground-water systems. The principle of superposition states that solutions to individual problems can be added together to obtain solutions...
Evaluation of the surface-water data network, Suwannee River basin, Florida, 1982
Roger P. Rumenik, J.E. Coffin
1984, Water-Resources Investigations Report 84-4245
In the 9,950 square mile area of the Suwannee River basin in Florida and Georgia, a network of 33 surface-water gaging stations operated for different periods of time from 1927 to 1982 was evaluated for its capability to provide program information for floodplain mapping, floodplain management, forecasting of flow extremes,...
Water-quality investigations of the Jordan River, Salt Lake County, Utah, 1980-82
D. W. Stephens
1984, Water-Resources Investigations Report 84-4298
Water-quality studies were conducted on the Jordan River, Utah, to investigate specific problems: dissolved oxygen, toxic substances, sanitary quality, and turbidity and suspended sediment. The dissolved oxygen decreased from 8 milligrams per liter at the Jordan Narrows to less than 5 milligrams per liter at 500 North Street. Chemical oxygen...
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...
Appraisal of the surficial aquifers in the Pomme de Terre and Chippewa River Valleys, western Minnesota
W.G. Soukup, D. C. Gillies, C. F. Myette
1984, Water-Resources Investigations Report 84-4086
The surf icial sands in the Pomme de Terre and Chippewa River valleys in Grant, Pope, Stevens, and Swift Counties have been studied to determine the occurrence, availability, and quality of ground water in these aquifers. In the northern part of the Pomme de Terre and Chippewa River valleys, the aquifers...
Glacial aquifer systems in the northeastern United States; a plan for study
F. P. Lyford, J.E. Dysart, A. D. Randall, A.L. Kontis
1984, Open-File Report 83-928
The U.S. Geological Survey project designed to study the availability and quality of water in glacial aquifers in the States of Maine, New Hampshire, Vermont, Massachusetts, Rhode Island, Connecticut, New York, New Jersey, Pennsylvania, and Ohio is scheduled for completion in 1986. It will focus on general principles that define...
