Summary 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 modelss 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, with only minor adaptations. The programs are written in a modular structure which facilitates modifications to the source code. Whenever these modifications are made, the program must be recompiled with a Fortran F77 compiler to incorporate the changes in the executable versions of the program code. The commands needed to link and compile the program depend on the type of compiler being used.
AIR3D is an adaptation of the ground-water flow code MODFLOW to simulate three dimensional air-flow in a heterogeneous, anisotropic unsaturated zone where air flow is induced through dry wells or trenches, as in vapor- extraction remediation. Although the code was developed primarily for this purpose, it can also be used to simulate natural air flow in the unsaturated zone caused by atmospheric-pressure variations.

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.

Description:
R-UNSAT is a computer model for the simulation of reactive,
multispecies transport in a heterogeneous, variably-saturated porous
media.
