US Geological Survey Toxic Substances Hydrology Program: Proceedings of the technical meeting, Phoenix, Arizona, September 26-30, 1988
Gail E. Mallard, Stephen E. Ragone, editor(s)
1989, Water-Resources Investigations Report 88-4220
Crude oil floating at the surface of a shallow aquifer of glacial outwash, near Bemidji, Minnesota, is altered by geochemical processes. Hydrocarbons from the oil are attenuated by several reactions that include aerobic and anaerobic microbial degradation. These degradation reactions result in the development of geochemical facies in the shallow...
Analytical solutions for one-, two-, and three-dimensional solute transport in ground-water systems with uniform flow
Eliezer J. Wexler
1989, Open-File Report 89-56
Analytical solutions to the advective-dispersive solute-transport equation are useful in predicting the fate of solutes in ground water. Analytical solutions compiled from available literature or derived by the author are presented in this report for a variety of boundary condition types and solute-source configurations in one-, two-, and three-dimensional systems...
Hydraulic characteristics of the New River in the New River Gorge National River, West Virginia
J.B. Wiley, David H. Appel
1989, Open-File Report 89-243
Traveltime, dispersion, water-surface and streambed profiles, and cross-section data were collected for use in application of flow and solute-transport models to the New River in the New River Gorge National River, West Virginia. Dye clouds subjected to increasing and decreasing flow rates (unsteady flow) showed that increasing flows shorten the...
