Sub Project 4: Groundwater

The SP 4 "Ground water" (Institute for water management IfW GmbH, Braunschweig) is interlinked with SP 3 and is similarly structured. The main objective is the development and the application of regional groundwater models in three representative zones in the research area: mangrove forest zone, zone in the upper and middle basin of the Thi Vai River and coastal zone. Due to the heavily pollution of surface water in the research area, groundwater is intensily used for domestic water supply, irrigation and for industrial water supply. The overexploitation of water in conjunction with changing climatic conditions requires a sustainable groundwater management as part of an integrated water resource management and hence the integration of SP 4 to the management system of EWATEC-COAST. Because of the weak data situation, own groundwater observation stations will be established and operated together with the Vietnamese partners. In parallel the hydrogeological model will be set up following the regional groundwater model, performed by the german model system FEFLOW. The calibration and the simulations for the status quo and the future situation will be carried for the same periods as in the SP 3. The key scientific challenge for groundwater modeling in this project is about being an integrated part of holistic water resources management procedures. Comprehensive databases for geologic borehole data, groundwater-related geophysical data and geologic models have to be set up. A regional groundwater-surface water model (interlinkange of SP 3 and SP 4) have to be set up and it has to be integrated to support water management.
