A 3-dimentional finite element groundwater model for density-dependent flow and transport through saturated-unsaturated porous media with stochastic approach (i.e. Latin Hypercube Sampling) FEMWATER-LHS has been developed. Numerical models like FEMWATER-LHS can not be regarded as representations of the real world because the complexity of natural hydrogeologic systems can never be captured in the discretized parameters of a numerical model. Instead, numerical modeling should be understood as a means of testing hydrologic hypotheses based on model parameters that best represent measured phenomena. However, testing hydrologic hypotheses often becomes time consuming because numerical models require complex data. To facilitate the modeling process, graphical user interfaces (GUI) are needed to handle geospatial information and simulation control parameters, as well as visualize the simulated results. For this purpose, a FEMWATER-GUI has been developed using Borland DelphiTM. This GUI for FEMWATER-LHS was developed using commercially available software developed by Argus Interware. The Argus Interware product, known as Argus Open Numerical Environment (Argus ONETM), is a model-independent, programmable system with Geographic-Information-System-like (GIS-like) functionality that includes automated griding and meshing capabilities for synthesising geospatial information and linking it with finite difference and finite element discretizations techniques. This GUIs must be used in conjunction with the Argus ONE commercial package. Together, these codes provide a convenient graphical pre- and post-processor, that significantly reduce the time and effort required for use of FEMWATER-LHS as hydrogeologic tool.
