Water budget and hydraulic aspects of artificial recharge, south coast of Puerto Rico
J. E. Heisel, Jose Raul Gonzalez
1979, Water-Resources Investigations Report 78-58
An analog model was used to evaluate ground-water conditions on the south coast of Puerto Rico. Water levels during a normal period and during an extended drought were simulated. Recharge and discharge values are reported. The model was also used to evaluate the possibilities of using treated waste water to...

Backwater at bridges and densely wooded flood plains, Yockanookany River near Thomastown, Mississippi
B.E. Colson, C. O. Ming, George J. Arcement
1979, Hydrologic Atlas 599
Floodflow data that will provide a base for evaluating digital models relating to open-channel flow were obtained at 22 sites on streams in Alabama, Louisiana, and Mississippi. Thirty-five floods were measured. Analysis of the data indicated methods currently in use would be inaccurate where densely vegetated flood plains are crossed...
Water-resources appraisal of the south-Arkansas lignite area
J. E. Terry, C. T. Bryant, A. H. Ludwig, J.E. Reed
1979, Open-File Report 79-924
The feasibility of developing lignite resources in south-central Arkansas is an important question at the present time (1978). Part of the concern is related to the possible impacts that mining and processing of lignite will have on water resources. Not only will the disturbance caused by excavating affect the quantity...

Geohydrologic setting of and seepage from a water-supply canal, Indianapolis, Marion County, Indiana
William R. Meyer
1979, Water-Resources Investigations Report 79-115
The Indianapolis Water Company Canal is underlain by alluvial and outwash deposits. The water level in the canal on July 21, 1978, was above the water table along the entire reach of the canal upstream from the Fall Creek aqueduct, and, therefore, water was seeping downward from the canal into...
Water quality of selected streams in the coal area of east-central Montana
P. W. McKinley
1979, Water-Resources Investigations Report 78-142
In October 1975 the U.S. Geological Survey established a network of nine data-collection stations on eight streams in Montana to monitor water quality in potential coal-mining areas. The report summarizes and evaluates the water-quality data that have been collected during the first 2 years (3 years for 1 station) of...
Saline-seep development in the Hailstone Basin, northern Stillwater County, Montana
Barney D. Lewis, Stephen G. Custer, Marvin R. Miller
1979, Water-Resources Investigations Report 79-107
As a result of an increase in saline seep occurrence in Montana, a study was begun in 1974 to determine the hydrogeology of saline seeps in the Hailstone basin. The aquifer is composed of colluvium of Holocene age. The impermeable Cretaceous Niobrara Formation underlies the saturated zone basinwide. The ground-water...

Status of surface-water modeling in the U.S. Geological Survey
Marshall E. Jennings, Nobuhiro Yotsukura
1979, Circular 809
The U.S. Geological Survey is active in the development and use of models for the analysis of various types of surface-water problems. Types of problems for which models have been, or are being developed, include categories such as the following: (1)specialized hydraulics, (2)flow routing in streams, estuaries, lakes, and reservoirs,...

Streamflow simulation studies of the Hillsborough, Alafia, and Anclote Rivers, west-central Florida
J.F. Turner Jr.
1979, Water-Resources Investigations Report 78-102
A modified version of the Georgia Tech Watershed Model was applied for the purpose of flow simulation in three large river basins of west-central Florida. The model was calibrated for six streamflow stations located in these basins using 4 years of historical and current rainfall, runoff, and estimated evapotranspiration data....

Distribution of nitrate and related nitrogen species in the unsaturated zone, Redlands and vicinity, San Bernardino County, California
John M. Klein, Wesley L. Bradford
1979, Water-Resources Investigations Report 79-60
Nitrogen in the unsaturated soil zone in the vicinity of Redlands in San Bernardino County, Calif., has been suspected as the source of nitrate in water from wells. Plans have been made to recharge the aquifer with imported surface water. If this occurs, the rising water table will intercept soluble...
Earth fissures and localized differential subsidence
Thomas L. Holzer, Earl Haig Pampeyan
1979, Open-File Report 79-951
Long tension cracks caused by declines of ground-water level at four sites in Arizona, California, and Nevada occur at points of maximum, convex-upward curvature in subsidence profiles based on relevelings of closely-spaced bench marks aligned perpendicular to the cracks. We conclude the cracks are caused by horizontal strains associated with...

The corrosive well waters of Egypt's western desert
Frank Eldridge Clarke
1979, Water Supply Paper 1757-O
The discovery that ground waters of Egypt's Western Desert are highly corrosive is lost in antiquity. Inhabitants of the oases have been aware of the troublesome property for many decades and early investigators mention it in their reports concerning the area. Introduction of modern well-drilling techniques and replacements of native...
A facility designed to monitor the unsaturated zone during infiltration of tertiary-treated sewage, Long Island, New York
Robert C. Prill, Edward T. Oaksford, James E. Potorti
1979, Water-Resources Investigations Report 79-48
A facility consisting of a circular recharge basin 6.10 meters in diameter with a central observation manhole was developed on Long Island, N.Y., to study the role of the unsaturated zone during aquifer recharge with tertiary-treated sewage. The manhole extends through most of the 7.5-meter-thick unsaturated zone, which is composed...
Ground water in Dale Valley, New York
Allan D. Randall
1979, Water-Resources Investigations Report 78-120
Dale Valley is a broad valley segment, enlarged by glacial erosion, at the headwaters of Little Tonawanda Creek near Warsaw , New York. A thin, shallow alluvial aquifer immediately underlies the valley floor but is little used. A deeper gravel aquifer, buried beneath many feet of lake deposits, is tapped...
