To guarantee optimal accessibility to the port of Antwerp, a deepening of the navigation channel was proposed within the Long Term Vision for the Scheldt estuary. An environmental impact assessment and an appropriate assessment were carried out for this project. From these studies it was concluded that the most preferred scenario for the enlargement of the navigation channel includes a strategy aiming at disposing dredged material near 3 sandbars in the Western Scheldt, creating opportunities for nature. To determine the optimal disposal strategy on a detailed and more practical level, research was performed by Flanders Hydraulics Research. The main objective of this study was to determine a detailed disposal strategy in order to maximize the ecological benefits, i.e. maximizing the potential creation of low dynamic intertidal and shallow water area. This paper describes the studies undertaken by Flanders Hydraulics Research to determine the most optimal disposal strategy. In a next part the most optimal disposal strategy resulting from the research will also be presented, as well as the strategy being used to evaluate this new disposal strategy.
