MT3D: A modular three-dimensional transport model

DESCRIPTION

MT3D is a three-dimensional groundwater flow and pollution model that simulates convective and dispersion fluxes as well as chemical reactions of a solute in an aquifer. It may use, depending upon the user choice, either the method of characteristics, a modified version of it, or a mixture of the two. It has been build in a modular fashion so that new modules, taking into account different phenomena, may be easily added to the code. MT3D can be considered as a three-dimensional extension of MODFLOW, from which it inherits both some computational methods and the overall program structure.
