The solute transport equations consider convective-dispersive transport in the liquid phase, as well as diffusion in the gaseous phase. The program may be used to analyze water and solute movement in unsaturated, partially saturated, or fully saturated porous media. The flow region itself may be composed of nonuniform soils having an arbitrary degree of local anisotropy. Flow and transport can occur in the vertical plane, the horizontal plane, or in a three-dimensional region exhibiting radial symmetry about the vertical axis. The governing flow and transport equations are solved numerically using Galerkin-type linear finite element schemes.
