SVFlux and ChemFlux: Software for two-dimensional/three-dimensional finite element variably saturated flow and transport modeling

SVFlux and ChemFlux are a pair of finite element models designed to simulate the movement of water and contaminants in two and three dimensions under variably saturated conditions. The transport simulator ChemFlux is designed as a companion to the flow simulator SVFlux. SVFlux and ChemFlux are commercial products developed by SoilVision Systems Ltd. and can be purchased via the company's Web site.

SVFlux and ChemFlux run under Microsoft Windows NT/2000/XP operating systems, and require a minimum of 128 MB RAM and approximately 150 MB hard drive space. The software includes Windows-based graphical user interface, numerical model engines, and post-processing programs. SVFlux and ChemFlux are suitable for numerous applications such as modeling of water and transport modeling in aquifers and the unsaturated zone, modeling of seepage across dams and geomembranes, and modeling of infiltration, excess pore water buildup, and dissipation. This article is based on two independent reviews of SVFlux (versions 4.05 and 5.04) and ChemFlux (versions 3.00 and 3.03).
