MT3D99 software is a full three-dimensional simulation of mass transport, which includes support for an implicit solution method, TVD Solution scheme, dual-porosity advection-diffusion, sorption, Monod kinetics, and Multi-species reactions, including chain first-order reaction Mother-Son and instant reactions between species. The model program is based on a modular structure to allow the simulation of transport processes independently or jointly.

This program is linked to three-dimensional groundwater model MODFLOW and can be applied easily using a pre-processor and post processor like Visual MODFLOW.

It is an ideal tool to simulate the migration of groundwater plumes both in two-dimensional or three-dimensional flow systems.

MT3D99 professional applications include:

• Advection simulation
• Dispersion simulation
• First-order decay simulations or production reactions
• Linear and nonlinear absorption simulation
