Our group uses and develops several tools for simulating groundwater flow and solute transport

• New x64 version VSAFT2, manual, and examples (2019.10.17) (Require Microsoft .NET framework 4.6.1 or higher).

• VSAFT2 (Variably Saturated Flow and Transport utilizing the Modified Method of Characteristics, in 2-D) is a Windows Graphical User Interface (GUI) for setting up, running and calibrating a variably saturated flow and transport finite element model (Yeh, et al., 1993) in 2 dimensions (either map view, cross-section or axis-symmetric flow). Model output is prepared for plotting in Tecplot (obtained independently), which allows easy and powerful visualization of results (including animations). VSAFT2 now includes several geostatistical model setup features, including random field generation of input parameters.

• A help file to aid setting up and calibrating a basic two-dimensional flow model in VSAFT2.

• A set of ten example scenarios taken from (Yeh, et al., 1993) are available for demonstrating 1D and 2D saturated and unsaturated flow and transport with VSAFT2 . When choosing a directory to unzip the examples into, remember that VSAFT2 cannot work from directories which contain spaces in them (i.e. "My Documents"). When opening these examples, simply point the open dialog from the file menu to the directory that contains the desired scenario (not any particular file in the directory).
