From the developer:
The VS2DI package contains all the tools that a user needs to create, run, and view results for a simulation of flow and transport through variably saturated porous media. The package seamlessly integrates a graphical user interface--within which the user can draw the simulated domain and enter or modify model parameters--with existing USGS models of flow and solute transport, and a postprocessor that displays simulation results.
