Abstract
    In this paper we study the transport of fine sediments by river-induced flushing, estuarine circulation and tidal asymmetry in the Sea Scheldt, Belgium. This study is carried out with an idealized schematization of the river, modeled as an exponentially converging river with constant depth and rectangular cross section, using Delft3D. Sediment is only imported from the lower sea boundary. Values for tidal amplitude and river flow, prescribed at the models’ open boundaries are comparable to those in the Scheldt. We show that a turbidity maximum is formed at the head of the salinity intrusion, driven by estuarine circulation, and in balance with river-induced flushing. For the given conditions, the model does not predict any fine sediment transport beyond that turbidity maximum.
