Abstract

The influence of fresh water distribution on SPM transport in the Dutch coastal zone J. M. de Kok National Institute for Coastal and Marine Management/RIKZ NL-2500 EX The Hague Abstract The rivers Rhine and Meuse - interconnected in the Dutch delta - flow into the North Sea through two outlets: the Rotterdam Waterway and the Haringvliet. The distribution of fresh water between the Rotterdam Waterway and the Haringvliet can be controlled by the management of sluices in the Haringvliet. A change in the management of the Haringvliet sluices can cause a different distribution of river run off over the two outlets and consequently a different salinity pattern around the mouths of Haringvliet and Rotterdam Waterway. This results also in a different transport pattern of cohesive sediment in the area, as it is strongly influenced by the salinity distribution. A case study with a high resolution 3D baroclinic tidal model combined with a cohesive sediment transport model was conducted to
