Regional groundwater flow modeling in the Oak Ridges Moraine area: building on the 3D geologic model

With more powerful computers and better software for data visualization, management, and analysis, it has become possible to build detailed 3D geologic models and then incorporate all the complexity and spatial variability in stratigraphy and hydraulic properties within high-resolution numerical models. This became a primary objective in developing a regional model for the Oak Ridges Moraine area in southern Ontario. Including the local variation in stratigraphy and aquifer properties along with better characterization of the surface water system led to a model that was much more representative of the flow system.
