3. DESCRIPTION OF PROGRAM OR FUNCTION

FEMWASTE is a two-dimensional transient model for the transport of dissolved constituents through porous media. The transport mechanisms include: convection, hydro- dynamic dispersion, chemical sorption, and first-order decay. The waste transport model is compatible with the water flow model (FEMWATER)) for predicting convective Darcy velocities in porous media which may be partially saturated.

4. METHOD OF SOLUTION

Implementation of quadrilateral isoparametric finite elements, bilinear spatial interpolation, asymmetric weighting functions, several time-marching techniques, and Gaussian elimination are employed in the numerical formulation of the transport equation. The application of the finite element method ensures that mass balance over the whole region is preserved. A mixture-dependent retardation factor is employed in the definition of solute sorption.
