AQUA3D - AQUA3D solves transient groundwater flow with anisotropic flow conditions. Solves transient transport of contaminants and heat with convection, decay, adsorption and velocity-dependent dispersion.
Argus Open Numerical Environments (Argus ONE) - A finite-element and finite-difference numerical preprocessor providing a unified modeling solution for groundwater models
SUTRA is a 2D ground water saturated-unsaturated transport model, a complete saltwater intrusion and energy transport model. SUTRA is integrated with Argus ONE for graphical pre and post processing.
