VSAFT: Variably Saturated Flow and Transport Simulation Software

Subsurface/Soil Hydraulics Analysis Software

VSAFT2 is a MSWindows Graphical User Interface (GUI) for setting up, running, calibrating, and doing inverse simulation on variably saturated flow and transport using either a rectangular or triangular element mesh in 2 dimensions. VSAFT2 couples a simple interface for quickly setting up problems with a powerful inverse parameter estimation method.

VSAFT3, a three dimensional version of VSAFT2, will be available soon, with similar capabilities to VSAFT2, but capable of simulating flow and transport for 3D geometries.
