MT3D-USGS

Mass Transport in 3-Dimensions - United States Geological Survey

The Mass Transport in 3-Dimensions - United States Geological Survey (MT3D-USGS) is a solute reactive transport groundwater model embedded within MODFLOW. Modelled processes include unsaturated flow transport, pollutant exchange between surface and groundwater, pollutant reactions, interspecies interactions.

Spatial Resolution
The model uses the same spatial resolution and grid structure as MODFLOW. Variable grid sizes can be nested and curvilinear or rectilinear.
Temporal Resolution
The model plot outputs are in half-days and days.
Outputs
Model outputs include solute reactions and fate within the aquifer-surface water system.
