The HST3D GUI is a powerful user –friendly interface for HST3D, one of the worlds’s most sophisticated ground-water modelling programs. It is integrated within the Argus Open Numerical Environments (Argus ONE). The HST3D GUI allows the user to enter all spatial data graphically , run HST3D, and visualize the results,. ARGUS ONE integrates CAD, GIS, Database, Conceptual Modeling, Geostatistics, Automatic Grid and Mesh Generation, and Scientific Visualisation within one comprehensive ground-water flow and associated heat and solute transport in three dimensions. The HST3D model may be used for analysis of problems such as those related to subsurface-waste injection, landfill leaching, saltwater intrusion, fresh-water recharge and recovery, radio-active waste disposal, water geothermal systems, and energy storage, HST3D enables youto:
*Asses well performance including type of well bore.
*Analyze pressure flow, heat and solute transport in the saturated zone with variable or constant density and viscosity.
*Model heat or solute transport coupled with ground-water flow or just ground-water flow.
*Predict chemical species transport including landfill contaminant movement.
*Predict waste injection into saline aquifers.
*Analyze freshwater storage in saline aquifers and saltwater intrusion in coastal aquifers.
*Model brine disposal/movement of connate water.
*Model contaminant (single species) transport in complex3-D aquifer systems.
*Model hydraulic barriers, liners and water-quality protection systems.
