Evaluation of Groundwater Budget and Assessment of Pumping Plans for Kang-Ping Development District Based on Modflow Simulations

摘要

In order to prevent possible over-extraction of the groundwater and maintain sustainability of groundwater supply in Kang-Ping Developing District (KPDD), a numerical simulation model of groundwater flow system was built based on analyzing and conceptualizing the local geological and hydro-geological conditions and solved by Visual Modflow. The results show that the model-simulated water heads match the measured historical water heads well and the model can be used to predict the groundwater flow field evolution. Evolution of groundwater flow field in the next 15 years was predicted under different pumping condition.
