Three-dimensional visualization models are an effective tool for understanding and communicating the complexity of an aquifer system. Using C-Tech Corporation’s Mining Visualization System (MVS) software, District staff have begun to develop a 3D model of the geologic framework for the Barton Springs segment of the Edwards Aquifer. The model is capable of displaying topography, aerial photos, water wells, potentiometric surfaces, geologic maps, water-quality data, dye tracing information, and caves. Future models may include the Trinity Aquifer and other site-specific projects.
