Stream simulation in an analog model of the ground-water system on Long Island, New York
Arlen W. Harbaugh, Rufus T. Getzen
1977, Water-Resources Investigations Report 77-58
The stream circuits of an electric analog model of the ground-water system of Long Island were modified to more accurately represent the relationahip between streamflow and ground-water levels. Assumptions for use of the revised circuits are (1) that streams are strictly gaining, and (2) that ground-water seepage into the streams...
Availability of ground water in the Piscataqua and other coastal river basins southeastern New Hampshire
J. E. Cotton
1977, Water-Resources Investigations Report 77-70
This map (scale 1:125,000) is a preliminary assessment of the availability of ground water in the Piscataqua and coastal river basins in New Hampshire. It is a generalization of several hydrogeologic factors and provides a guide for ground-water exploration, which is useful in water- and land-use planning. The best aquifers...
Hydrologic reconnaissance evaluation of the Federal Capital Territory and surrounding areas, Nigeria
L.R. Peterson, Gerald Meyer
1977, Open-File Report 77-596
Initial moderate water requirements of the new Federal Capital Territory in Central Nigeria are available from the two large rivers, the Niger and Benue, from the smaller Gurara River, and possibly from several smaller streams. Ground water in the southwestern part of the Territory and in adjacent areas along the...
Maps showing ground-water conditions in the southern part of the Chinle area, Apache County, Arizona, 1976
G. W. Levings, C. D. Farrar
1977, Water-Resources Investigations Report 77-50
The southern part of the Chinle area includes about 2,100 sq mi in northeastern Arizona and is entirely in the Navajo Indian Reservation. The main source of water is the ground water in the several aquifers that are made up of one or more formations. The aquifers are stacked one...
Hydrologic monitoring of a waste-injection well near Milton, Florida, June 1975 - December 1976
Charles A. Pascale, J.B. Martin
1977, Open-File Report 77-368
Hydraulic and chemical data were collected through a monitoring program conducted by the U.S. Geological Survey at an industrial liquid-waste injection site 6 mi southwest of Milton, Fla., in Santa Rosa County. The injection system is described. Data include injection rates, volumes, and pressures; water-level data at three monitor wells...
Maps showing ground-water conditions in the northern part of the Chinle area, Apache County, Arizona, 1976
G. W. Levings, C. D. Farrar
1977, Water-Resources Investigations Report 77-35
The northern part of the Chinle area includes about 3,000 sq mi in northeastern Arizona and is entirely in the Navajo Indian Reservation. The main source of water is from the several aquifers that are made up of one or more formations. The aquifers are stacked one on the other...
Maps showing ground-water conditions in the Monument Valley and northern part of the Black Mesa areas, Navajo, Apache, and Coconino counties, Arizona, 1976
G. W. Levings, C. D. Farrar
1977, Water-Resources Investigations Report 77-44
The Monument Valley and the northern part of the Black Mesa areas include about 2,700 sq mi in northeastern Arizona and are entirely in the Navajo and Hopi Indian Reservations. The main source of water is from the several aquifers that are made up of one or more formations. The...

Methods for collection and analysis of aquatic biological and microbiological samples
T. A. Ehlke, G. A. Irwin, B.W. Lium, K. V. Slack
Phillip E. Greeson, editor(s)
1977, Techniques of Water-Resources Investigations 05-A4
Chapter A4 contains methods used by the U.S. Geological Survey to collect, preserve, and analyze waters to determine their biological and microbiological properties. Part 1 discusses biological sampling and sampling statistics. The statistical procedures are accompanied by examples. Part 2 consists of detailed descriptions of more than 45 individual methods,...
Digital model analysis of the principal artesian aquifer, Savannah, Georgia area
H. B. Counts, R.E. Krause
1977, Water-Resources Investigations Report 76-133
A digital model of the principal artesian aquifer has been developed for the Savannah, Georgia, area. The model simulates the response of the aquifer system to various hydrologic stresses. Model results of the water levels and water-level changes are shown on maps. Computations may be extended in time, indicating changes...
Derivation of equations describing solute transport in ground water
Leonard F. Konikow, D.B. Grove
1977, Water-Resources Investigations Report 77-19
A general equation describing the three-dimensional transport and dispersion of a reacting solute in flowing ground water is derived from the principle of conservation of mass. The derivation presented is more detailed but less rigorous than derivations published previously. The general solute-transport equation relates concentration changes to hydrodynamic dispersion, convective...
Theoretical drawdown due to simulated pumpage from the Ohio River alluvial aquifer near Siloam, Kentucky
J. M. Kernodle
1977, Water-Resources Investigations Report 77-24
Theoretical drawdown due to simulated pumpage was determined for a site near Siloam, Kentucky by using a digital ground-water-flow model. The maximum sustained yield of water from the single well was shown to be less than 900 gallons per minute, and, for a simulated pumping rate of 450 gallons per...
