MODFLOWT Overview
MODFLOWT is an enhanced version of the USGS MODFLOW model which includes packages to simulate advective-dispersive contaminant transport. Fully three-dimensional, MODFLOWT simulates transport of one or more miscible species subject to adsorption and decay through advection and dispersion. MODFLOWT performs groundwater simulations utilizing transient transport with steady-state flow, transient flow, or successive periods of steady-state flow. Groundwater flow data sets created for the original MODFLOW model function without alteration in MODFLOWT; thus extension of modeling projects to simulate contaminant transport is much easier using MODFLOWT than any other commercially-available model. MODFLOWT is thoroughly tested and has been bench-marked against other transport codes including MT3D, SWIFT and FTWORK. A comprehensive and pragmatic approach to contaminant transport has been incorporated into MODFLOWT which allows for three distinct directional dispersivity values, multiple chemicals and a rigorous treatment of the hydrodynamic dispersion tensor.
