MT3D99 - a modular 3d groundwater solute transport model
MT3D99 Categories: solute transport models - saturated zone, MODFLOW programs
MT3D99 Overview
MT3D is a comprehensive three-dimensional numerical model for simulating solute transport
in complex hydrogeologic settings. MT3D has a modular design that permits simulation of transport processes independently or jointly. MT3D is capable of modeling advection in complex steady-state and transient flow
fields, anisotropic dispersion, first-order decay and production reactions, and linear and nonlinear sorption. The new MT3D99 can also handle bioplume-type reactions, monad reactions, and daughter products. This
enables MT3D99 to do multi-species reactions and simulate or assess natural attenuation within a contaminant plume. MT3D99 is linked with the USGS groundwater flow simulator, MODFLOW, and is designed specifically to
handle advectively-dominated transport problems without the need to construct refined models specifically for solute transport.
