Groundwater Transport Process (GWT)

Overview of GWT

The MF2K-GWT model is an enhanced version of MODFLOW-2000 that incorporates the additional capability to simulate solute-transport processes and compute changes in concentration of a dissolved chemical constituent due to advection, hydrodynamic dispersion, retardation, decay, matrix diffusion, and mixing with multiple fluid sources.
