The most efficient approach for building realistic, complex models is the conceptual model approach. With this approach, a conceptual model is created using GIS objects (points, arcs, and polygons) and elevation data (solids, scatter points, or boreholes). The conceptual model is constructed independently of a grid or mesh.

The conceptual model is a high-level description of the site including sources/sinks, the boundary of the domain to be modeled, recharge and evapotranspiration zones, and site stratigraphy. Once the conceptual model is complete, a grid or mesh is automatically constructed to fit the conceptual model, and the model data are converted from the conceptual model to the cells of the grid.
