Fresh-salt water distribution in the Zwin estuary before and after the planned expansion

Abstract
Plans are made to extend the tidal flat area around the silt-up Zwin estuary which is situated around the Dutch-Belgian border. First, the evolution of the fresh-salt water flow and distribution is simulated in this area and the surrounding polder area for a period of 50 years taking into account forecasted sea-level rise. The initial fresh-salt water distribution is based on the map of the depth of the fresh-salt water interface and is completed by electromagnetic borehole loggings. MOCDENS3D is used to simulate the 3D groundwater flow models. After this first simulation the evolution of the fresh-salt water distribution and flow is simulated for a period of 50 years taking into account the expansion of the estuary and its surrounding tidal flats with a surface of 120 hectare. This action results in an increase of the salt water seepage area in the adjacent polder area. The model shows that this increase can be mitigated by the application of deep drainage in stead of the traditional shallow drainage. In the long run this mitigating measure allows even the reduction of the present salt water seepage area.
