Importance of return flow as a component of water use
L. C. Trotta, M.S. Horn
1990, Open-File Report 90-197
Understanding the relation between the hydrologjc cycle and water use is important for effective water-resources management. The hydrologic cycle is the natural pathway of water from evaporation to precipitation to infiltration or runoff and to storage from which evaporation can again occur. The science of water use is the study...
Structure and application of an interface program between a geographic-information system and a ground-water flow model
P. C. Van Metre
1990, Open-File Report 90-165
A computer-program interface between a geographic-information system and a groundwater flow model links two unrelated software systems for use in developing the flow models. The interface program allows the modeler to compile and manage geographic components of a groundwater model within the geographic information system. A significant savings of time...
Recharge rates and aquifer hydraulic characteristics for selected drainage basins in middle and east Tennessee
A.B. Hoos
1990, Water-Resources Investigations Report 90-4015
Quantitative information concerning aquifer hydrologic and hydraulic characteristics is needed to manage the development of ground-water resources. These characteristics are poorly defined for the bedrock aquifers in Middle and East Tennessee where demand for water is increasing. This report presents estimates of recharge rate, storage coefficient, diffusivity, and transmissivity for...
Preliminary investigation of soil and ground-water contamination at a U.S. Army Petroleum Training Facility, Fort Lee, Virginia, September-October 1989
W. G. Wright, J. D. Powell
1990, Open-File Report 90-387
Fuel-oil constituents in the soil and groundwater at the Fort Lee Petroleum Training Facility near Petersburg, Virginia, were studied by the U.S. Geological Survey (USGS) in cooperation with the Department of Defense, U.S. Army. The study included installation of 25 groundwater monitoring wells and description of groundwater flow patterns of...
Sources and summaries of water-quality information for the Rapid Creek basin, western South Dakota
John S. Zogorski, E.M. Zogorski, T.E. McKallip
1990, Open-File Report 90-115
This report provides a compilation of water quality information for the Rapid Creek basin in western South Dakota. Two types of information are included: First, past and current water quality monitoring data collected by the South Dakota Department of Water and Natural Resources, U.S. Forest Service, U.S. Geological Survey, and...
Reconnaissance investigation of water quality, bottom sediment, and biota associated with irrigation drainage in the American Falls Reservoir area, Idaho, 1988-89
Walton H. Low, William H. Mullins
1990, Water-Resources Investigations Report 90-4120
Increased concern about the quality of irrigation drainage and its potential effects on human health, fish, and wildlife prompted the Department of the Interior to begin a program during late 1985 to identify irrigation-induced water-quality problems that might exist in the Western States. During `988, the Task Group on Irrigation...
