3D visualization of data from groundwater flow and transport models

[摘要] English: Groundwater flow and transport models produce large amounts of data, which the humanbrain cannot possibly grasp. Taking advantage of the natural abilities of the human visionsystem, 3D visualization is often the tool of choice for understanding and communicatingconceptual models, verifying model input, understanding model output, explaining andcommunicating conclusions and recommendations, and motivating expenses. A 3Dvisualization tool has therefore been developed for intelligence amplification of model data.The tool is based on a groundwater modeling system (Processing MODFLOW) and makesuse of the results from existing groundwater flow (MODFLOW) and transport models(MT3DMS, PHT3D and RT3D.). The Visualization Toolkit (vtk), a C++ class library forvisualization was used to render 3D geohydrological objects. Realistic scenes of 3Dgeospatial models and 3D distributions of geohydrological properties, such as hydraulicconductivity, heads and solute concentrations, can be rendered.The advantages of 3D visualization are evident by applying the visualization tool to casestudies.
