Design of the MEPAS Saturated Zone Transport Module
The migration and fate of contaminants through the groundwater are described by a three-dimensional, advective-dispersive equation for solute transport. The results are based on semianalytical solutions (i.e., solutions that require numerical integration) that are well established in the scientific literature. The Saturated Zone Transport Module accounts for the major mechanisms of constituent mobility (i.e., adsorption/desorption), persistence (i.e., degradation or decay), advection, and hydrodynamic dispersion.
A full description of the design parameters, as well as scientific formulations for the various mechanims, can be found in Whelan et al., 1996 (PNNL-10907) and can be accessed online by following this link:
