MT3D-USGS: GROUNDWATER SOLUTE TRANSPORT SIMULATOR FOR MODFLOW

June 28, 2019

View Software Release


OVERVIEW OF MT3D-USGS

Sources/Usage: Public Domain. View Media Details
Cover image from the MT3D-USGS user manual.

MT3D-USGS capabilities and features include:

 * supports simulation of transport using MODFLOW 6 flow solution (structured
   grids only)
 * unsaturated-zone transport;
 * transport within streams and lakes, including solute exchange with connected
   groundwater;
 * capability to route solute through dry cells that may occur in the
   Newton-Raphson formulation of MODFLOW (that is, MODFLOW-NWT);
 * new chemical reaction package options that include the ability to simulate
   interspecies reactions and parent-daughter chain reactions;
 * new pump-and-treat recirculation package that enables the simulation of
   dynamic recirculation with or without treatment for combinations of wells
   that are represented in the flow model, mimicking the above-ground treatment
   of extracted water;
 * reformulation of the treatment of transient mass storage that improves
   conservation of mass and yields solutions for better agreement with
   analytical benchmarks;
 * separate specification of the partitioning coefficient (Kd) within mobile and
   immobile domains;
 * capability to assign prescribed concentrations to the top-most active layer;
 * change in mass storage owing to the change in water volume now appears as its
   own budget item in the global mass balance summary;
 * ability to ignore cross-dispersion terms;
 * definition of Hydrocarbon Spill-Source Package (HSS) mass loading zones using
   regular and irregular polygons, in addition to the currently supported
   circular zones; and
 * ability to specify an absolute minimum thickness rather than the default
   percent minimum thickness in dry-cell circumstances.


 


DOWNLOAD CURRENT VERSION OF MT3D-USGS

MT3D-USGS Version 1.1.0 06/28/2019 is the current release.

 * Summary of MT3D-USGS
 * Readme and installation instructions
 * MT3D-USGS program, source code, user guides, and example problems


 


DOCUMENTATION FOR MT3D-USGS

Bedekar, V., Morway, E.D., Langevin, C.D., and Tonkin, M., 2016, MT3D-USGS
version 1: A U.S. Geological Survey release of MT3DMS updated with new and
expanded transport capabilities for use with MODFLOW: U.S. Geological Survey
Techniques and Methods 6-A53, 69 p., http://dx.doi.org/10.3133/tm6A53
This is the initial report that describes the theory and use of MT3D-USGS.


 


SUPERSEDED MT3D-USGS VERSIONS

MT3D-USGS is not a replacement for MT3DMS. Separate updates to both codes will
likely continue in the future. Therefore, MT3D users should check appropriate
webpages for updates and releases of MT3D-USGS and MT3DMS separately. (MT3DMS is
not a USGS software product; USGS cannot assist with MT3DMS questions or
support.) The original MT3DMS software is available at
https://web.archive.org/web/20170129200934/http://hydro.geo.ua.edu/mt3d/

HOW TO CITE MT3D-USGS

This USGS software has two citations associated with it.

 1. The report citation is for the original report or article documenting the
    underlying theory, methods, instructions, and (or) applications at the time
    the initial version of the software was released. This digital object
    identifier (DOI) is for the report.
 2. The software release citation is for the software/code itself (now referred
    to by USGS as a "Software Release") and references a specific version of the
    code and associated release date. This DOI links to the code.

In instances where an author is citing use of this software, it would be
appropriate to cite both the report documenting the code and the specific
software release version that was used.
