Application of virtual reality technology to modeling hydrogeological structure and hydraulic head in the Suzhou-Wuxi-Changzhou area,China

Based on the developing environment of Visual C++ and OpenGL,the visualizing model of 3D hydrogeological structure and hydraulic head in the aquifers in the Suzhou-Wuxi-Changzhou area in eastern China has virtually been simulated,for building the model of 3D hydrogeological structure and hydraulic head is the basic works when the mechanism of land subsidence is examined.In this model,the virtually simulated geological environment in which groundwater occurs is vividly similar to the real case and hydraulic heads of the aquifers can be expressed in the geological framework.By interactively operating the virtual model,a physical effect can be produced and researchers can learn hydrogeological information such as the strata at any position or any depth,the hydraulic links between aquifers and dynamic process of uplifting or depressing of groundwater levels,and so on.The work makes it easy to study the mechanism of subsidence.
