Potential for leakage among principal aquifers in the Memphis area, Tennessee
D. D. Graham, W. S. Parks
1986, Water-Resources Investigations Report 85-4295
The principal aquifers in the Memphis area consist primarily of sand or sand and gravel, and the confining beds consist of clay, silt, sand, and lignite. The Jackson Formation and upper part of the Claiborne Group serve as the confining bed separating the water table aquifers from the Memphis Sand;...
Approximate change in water levels in wells in the Chicot and Evangeline Aquifers 1977-86 and 1985-86, and measured compaction 1973-86, in the Houston-Galveston region, Texas
James Frank Williams III, C.E. Ranzau Jr.
1986, Open-File Report 86-135
This report consists of: (1) Four maps that present data on water level changes during 1977-86 and 1985-86 in the Chicot and Evangeline aquifers, Houston, Texas, and (2) one set of graphs and one map that present data on land subsidence and compaction of subsurface materials for 1973-86. (USGS)...
Methods for estimating magnitude and frequency of floods in Montana based on data through 1983
R. J. Omang, Charles Parrett, J. A. Hull
1986, Water-Resources Investigations Report 86-4027
Equations are presented for estimating flood magnitudes for ungaged sites in Montana based on data through 1983. The State was divided into eight regions based on hydrologic conditions, and separate multiple-regression equations were developed for each region. These equations relate annual flood magnitudes and frequencies to basin characteristics and are...
Water-resources activities of the U.S. Geological Survey in Montana, October 1985 through September 1986
Robert S. Roberts
1986, Open-File Report 86-421-W
Water resources programs and activities of the U.S. Geological Survey in Montana consist principally of hydrologic data collection (6 projects); local areal, or statewide hydrologic investigation (12 projects); and research (1 project). The work is supported by direct Federal funding, by transfer of funds from other federal agencies, and by...
Free-air gravity anomaly map of the Long Island Platform
D. R. Hutchinson, W.D. Leeds, Robin Bell, J. A. Grow
1986, Miscellaneous Field Studies Map 1807
The U.S. Geological Survey (USGS) has collected marine gravity data along the U.S. Atlantic continental margin during the last decade. This map of the Long Island platform combines the data used to make the preliminary free-air gravity anomaly map of the Atlantic continental margin (Grow and others, 1976) with the...
Progress report on the effects of highway construction on suspended-sediment discharge in the Coal River and Trace Fork, West Virginia, 1975-81
S. C. Downs, David H. Appel
1986, Water-Resources Investigations Report 84-4275
Construction of the four-lane Appalachian Corridon G highway disturbed about 2 sq mi in the Coal River and 0.35 sq mi of the 4.75 sq mi Trace Fork basin in southern West Virginia. Construction had a negligible effect on runoff and suspended-sediment load in the Coal River and its major...
Quaternary geologic map of the Jacksonville 4 degrees x 6 degrees quadrangle, United States
M.S. Knapp, M. S. Friddell, David L. Weide, David S. Fullerton
Gerald M. Richmond, editor(s)
1986, IMAP 1420(NH-17)
This map is part of the Quaternary Geologic Atlas of the United States (I-1420). It was first published as a printed edition in 1986. The geologic data have now been captured digitally and are presented here along with images of the printed map sheet and component parts as PDF files. The...
Low-flow profiles of the upper Ocmulgee and Flint rivers in Georgia
R.F. Carter, E. H. Hopkins, H. Perlman
1986, Water-Resources Investigations Report 86-4176
This report provides low-flow information for use in evaluating the capacity of streams to supply withdrawals or to accept waste loads from potential new industries without exceeding the limits of State water-quality standards. The report is the first phase of a study of all stream basins north of the Fall...
Geohydrology of the glacial-outwash aquifer in the Baldwinsville area, Seneca River, Onondaga County, New York
Timothy S. Pagano, David B. Terry, Arlynn W. Ingram
1986, Water-Resources Investigations Report 85-4094
Seven sheets of map data comprise this geohydrologic report. Sheet 1, surficial geology, illustrates the distribution of: open water areas; artificial fill; made land; urban land; alluvial silt and sand; alluvial sand and gravel; peat, marl, muck and clay; lake silt and/or clay; delta sand and gravel; beach sand and...
Quality of water resources of the Ouachita National Forest, Arkansas
Elizabeth F. Cole, E. E. Morris
1986, Water-Resources Investigations Report 86-4166
Surface water and groundwater quality was documented in the Ouachita National Forest by collecting surface water quality data at 15 points and groundwater quality data at 11 sites from April 1984 through August 1985. The data were compared to drinking water standards and the results are tabulated. Surface water in...
Ground-water and surface-water-level data at Rindge Tract on the Stockton Deep Water Ship Channel, San Joaquin County, California, 1983-84
Michael J. Pierce, Karen L. Johnson
1986, Open-File Report 85-573
The Sacramento-San Joaquin Delta is formed at the confluence of the two major rivers that drain the Central Valley of California. The Sacramento and San Joaquin Rivers and many interconnecting sloughs meandered back and forth across the tidelands, frequently overflowing their banks. Approximately 1 ,100 miles of levees were constructed...
Detection of contaminant plumes in ground water of Long Island, New York, by electromagnetic terrain-conductivity surveys
Thomas J. Mack, P. E. Maus
1986, Water-Resources Investigations Report 86-4045
Electromagnetic terrain conductivity surveys were conducted at four landfills in Suffolk county and at an artificial recharge site in Nassau County to assess the feasibility of this technique for detecting contaminant plumes. The technique was successful at three of the landfills; results compared closely with those indicated by specific conductance...
Maps showing altitude of the potentiometric surface and changes in water levels in the aquifer in the Sparta and Memphis Sands in eastern Arkansas, spring 1985
Joe Edds, D. J. Fitzpatrick
1986, Water-Resources Investigations Report 86-4084
Aquifers in the Tertiary Sparta and Memphis Sands are a major source of water supply for much of eastern and south-central Arkansas. Major withdrawals occur from the aquifer for industrial and public supply, with generally lesser but locally significant amounts withdrawn for agricultural uses. Water level data from wells tapping...
