STANMOD (STudio of ANalytical MODels) is a Windows based computer software package for evaluating solute transport in porous media using analytical solutions of the convection-dispersion solute transport equation.

Version 1.0 of STANMOD includes the following models for one-dimensional transport problems:

• CXTFIT 2.0 [Toride et al., 1995]
• CFITM [van Genuchten,1980]
• CFITIM [van Genuchten, 1981]
• CHAIN [van Genuchten, 1985]

Version 2.0 of STANMOD also includes the following models for two- and three-dimensional transport problems.

• 3DADE [Leij and Bradford, 1994]
• N3DADE [Leij and Toride, 1997]

SYSTEM REQUIREMENTS

Intel Pentium processor, 16 Mb RAM, hard disk with at least 20 Mb free disk space, VGA graphics (SVGA with 256 colors recommended), MS Windows 95 or higher.
