R-UNSAT Mathematical Model for Simulating Transport of Volatile Organic Compounds
Entry ID: 02-usgs-R-UNSAT-00

[ Update this Record ]

Summary
Abstract: The Galloway research team has developed and documented three computer models
(AIR2D, AIR3D, and R-UNSAT) for simulating flow and transport in the
unsaturated zone that are available to the public. These models were funded
by the Toxics Substances Hydrology Program. The computer codes are written in
Fortran F77 and run on a variety of computer systems, including mainframe and
personal computers, ... View entire text

Description: AIR2D is a flow model for simulating the movement of air to or from a
single borehole screened in the unsaturated zone and can be applied to
predict a steady-state flow field associated with vapor extraction.
