MT3D-USGS: Groundwater Solute Transport Simulator for MODFLOW
MT3D-USGS is a USGS updated release of the groundwater solute transport code MT3DMS. MT3D-USGS includes new transport modeling capabilities to accommodate flow terms calculated by MODFLOW packages that were previously unsupported by MT3DMS and to provide greater flexibility in the simulation of solute transport and reactive solute transport.
MT3D-USGS capabilities and features include:
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.
