The port authority is preparing plans for a new port expansion, which add new challenges for understanding the hydrodynamic processes in this area. A new physical scale model with fixed bed is constructed at Flanders Hydraulics Research (in Dutch: Waterbouwkundig Laboratorium) to study this highly dynamic tidal region at the Belgium coast. The main aim of the present research is to set up a well calibrated model using the on-site data which will help in a profound understanding of the important hydrodynamic processes around and inside the port. The next step will be testing and evaluating the recommended port expansions.
