Abstract
    The rivers Rhine and Meuse - interconnected in the Dutch delta - flow into the North Sea through two outlets: the Rotterdam Water Way and the Haringvliet. The distribution of fresh water between the Rotterdam Water Way 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 Water Way. 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 assess the intrusion of cohesive sediment in the Rotterdam Water Way. The model results indicate a reduction of 30 - 60% of the deposition of cohesive sediment in harbours and shipping channels as a result of a different distribution of fresh water over the two outlets.
