HYDROGEOCHEM (HGC) is a physical-based flexible and comprehensive computational model for simulating coupled THMC (Thermal-Hydraulic-Mechanical-Chemical) processes in saturated-unsaturated subsurface media.
HYDROGEOCHEM (HGC) model has been successfully used in studying radioactive waste and subsurface contamination. This model may (1) strategically guide monitoring of field investigations, (2) accurately determine environmental safety and impacts of natural processes and anthropogenic activities, (3) significantly assist and advance the design of engineering systems, and (4) correctly and realistically interpret scientific findings. HGC model can simulate a single process or partially or fully coupled THMC processes. HGC can cover a large variety of real-world subsurface problems due to its comprehensive mathematical formulations and powerful numerical capabilities.
