This measure, in the mesohaline zone of the Scheldt, aimed to create a new intertidal wetland with a clear positive effect on habitat loss and degradation and this piece of land is given back to the estuary. At a larger scale this type of measure could also generate a positive effect on the hydrographic regime, water and sediment chemical quality and relative sea level rise. Finally, sedimentation on the wetland can reduce the need for maintenance dredging in the main river.
