PhD Defence: Sediment dynamics of a tidal freshwater wetland system, a case study in the Biesbosch

Short-term sediment fluxes within the wetland system are controlled by river discharge and sediment concentration, tide, and wind. The daily sediment budget increases for higher upstream river discharge. However, trapping efficiencies decrease for increasing wind strengths and raised river discharges due to increased resuspension.

The suspended sediment concentration in the feeding river is, the major factor controlling the balance between sedimentation during conditions of low and average discharge and resuspension during wind or raised discharge events. Therefore, a sufficiently high suspended sediment concentration is critical for wetland restoration projects.
