TOUGH

Transport of Unsaturated Groundwater and Heat

Transport of Unsaturated Groundwater and Heat (TOUGH) is a groundwater model designed to evaluate site remediation, geothermal energy, carbon sequestration, and oil and gas reservoir evaluations. Model capabilities include a coupled transport model for heat and water vapor, unsaturated groundwater flow and gas flow in porous media.

Spatial Resolution
Integral finite difference method directly derives the spatial grid based on the equations being solved in the mass and energy balance.
Temporal Resolution
Model uses automatic time step adjustment. Time is discretized implicitly based on first order backward finite difference calculation.
Outputs
Model output includes heat and mass transfer behavior.
