MT3DMS (Modular Transport, 3-Dimensional, Multi-Species model) is a modular three-dimensional transport model for the simulation of advection, dispersion, and chemical reactions of dissolved constituents in groundwater systems (Zheng, 1990). MT3DMS uses a modular structure similar to the structure utilized by MODFLOW. MT3DMS is used in conjunction with [[GMS:MODFLOW|MODFLOW]] in a two step flow and transport simulation. Heads and cell-by-cell flux terms are computed by MODFLOW during the flow simulation and are written to a specially formatted file. This file is then read by MT3DMS and utilized as the flow field for the transport portion of the simulation. | MT3DMS (Modular Transport, 3-Dimensional, Multi-Species model) is a modular three-dimensional transport model for the simulation of advection, dispersion, and chemical reactions of dissolved constituents in groundwater systems (Zheng, 1990).

==Background== | |||
MT3DMS is a newer version of the old MT3D model that was distributed with earlier versions of GMS. GMS 8.0 and later now run MT3DMS version 5.3 (built in Feb 2010). MT3DMS differs from MT3D in that it allows for multi-species transport, supports additional solvers, and allows for cell-by-cell input of all model parameters. | MT3DMS is a newer version of the old MT3D model that was distributed with earlier versions of GMS.

It is assumed that the reader has a basic knowledge of MT3DMS and is familiar with the MT3DMS [http://gmsdocs.aquaveo.com/mt3dms.pdf original] and [http://gmsdocs.aquaveo.com/mt3dms_v5_supplemental.pdf supplementary] documentation (Zheng, 1990). Only the details of the GMS graphical interface to MT3DMS are described in these pages. | |||
==MT3DMS in GMS== | |||
A special version of MT3DMS is distributed with GMS. This version of MT3DMS has been modified to output [[GMS:Dataset Files|GMS dataset files]]. | A special version of MT3DMS is distributed with GMS, and the model is included with all [http://www.aquaveo.com/software/gms-pricing paid editions] of GMS. This version of MT3DMS has been modified to output [[GMS:Dataset Files|GMS dataset files]]. GMS supports MT3DMS as a pre- and post-processor where the input data for MT3DMS is generated by GMS and saved to a set of files. These files are then read by MT3DMS when MT3DMS is executed from the GMS menu. The output super file (*.MTS) generated from MT3DMS is then imported to GMS for [[GMS:MODFLOW#Post Processing|post-processing]] and viewing. | ||
==Supported MODFLOW Packages== | |||
MT3DMS v5.3 supports the following MODFLOW packages that are also supported in GMS: BAS6, BCF, LPF, HUF, HFB, CHD, WEL, DRN, RIV, GHB, RCH, EVT, STR, and LAK. | |||
