Detailed Description

English {{currentDetailLanguage}} English

Quoted from: https://www.usgs.gov/software/mt3d-usgs-groundwater-solute-transport-simulator-modflow 

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.

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Superseded MT3D-USGS Versions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 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.
