Enhanced job control language procedures for the SIMSYS2D two-dimensional water-quality simulation system
G.A. Karavitis
1984, Water-Resources Investigations Report 84-4052
The SIMSYS2D two-dimensional water-quality simulation system is a large-scale digital modeling software system used to simulate flow and transport of solutes in freshwater and estuarine environments. Due to the size, processing requirements, and complexity of the system, there is a need to easily move the system and its associated files...
Geohydrology of the valley-fill aquifer in the Cohocton area, upper Cohocton River, Steuben County, New York
David B. Terry, Timothy S. Pagano, Martha L. Shaw, Arlynn W. Ingram
1984, Water-Resources Investigations Report 85-4040
The Cohocton valley-fill aquifer, composed of outwash, kame, and alluvial sand and gravel, is highly productive and is in hydraulic contact with the Cohocton River. Potential well yields range from 50 to more than 1,000 gallons per minute. Most of the aquifer is under shallow water-table conditions and vulnerable to...
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...
Hydrogeology of eastern Michaud Flats, Fort Hall Indian Reservation, Idaho
N.D. Jacobson
1984, Water-Resources Investigations Report 84-4201
Groundwater in Michaud Flats, southeastern Idaho, is developed extensively for irrigation and industry. Extensive clay beds overlie the Bighole Basalt and Sunbeam Formation, which yield most of the water for irrigation and industrial wells; artesian aquifers in these rock units have heads below land surface and near those in the...
Geohydrology of the valley-fill aquifer in the Bath area, Lower Cohocton River, Steuben County, New York
Timothy S. Pagano, D.B. Terry, M.L. Shaw, A.W. Ingram
1984, Water-Resources Investigations Report 85-4095
The Bath valley-fill aquifer, southern New York, composed of outwash, ice-contact, and ice-disintegration sand and gravel, is highly productive and is in many areas in hydraulic contact with the Cohocton River. Potential well yields range 50 to more than 1,000 gallons per minute. Most of the aquifer is under shallow...
Maps showing altitude of the potentiometric surface and changes in water level of the Sparta sand and Memphis sand aquifers in Eastern Arkansas, spring 1983
Joe Edds, Daniel J. Fitzpatrick
1984, Water-Resources Investigations Report 84-4265
The Sparta Sand and the Memphis Sand aquifers are a major source of industrial and public water supply and a minor but locally significant source of water for agricultural purposes in eastern and south-central Arkansas. The potentiometric surface map for this aquifer, compiled from water-level measurements made during the spring...
Water-table contours, directions of ground-water movement, and measurements of inflow to American Falls Reservoir, southeastern Idaho, April 1984
H.W. Young
1984, Water-Resources Investigations Report 84-4269
In 1978 the U.S. Geological Survey began a 5-year study of the High Plains regional aquifer system to provide hydrologic information for evaluating the effects of long-term development of the aquifer and to develop a capability for predicting aquifer response to alternative changes in ground-water management. By use of a...
