HYDROGEOCHEM 4.0:
A Coupled Model of Fluid Flow, Thermal Transport, and HYDROGEOCHEMical Transport through Saturated-Unsaturated Media

The computer program HYDROGEOCHEM 4.0 is a coupled model of water flow, thermal transport, solute transport, and geochemical kinetic/equilibrium reactions in saturated/unsaturated porous media in two dimensions.

HYDROGEOCHEM 5.0:
A Three-Dimensional Model of Coupled Fluid Flow, Thermal Transport, and HYDROGEOCHEMical Transport through Variably Saturated Conditions

The computer program HYDROGEOCHEM 5.0 is a numerical model of fluid flow, thermal transport, hydrologic transport, and biogeochemical kinetic/equilibrium reactions in saturated/unsaturated media. It is a three-dimensional version of the two-dimensional HYDROGEOCHEM 4.0.
