In-situ monitoring of WID activities in the Calandkanaal area of the Port of Rotterdam (PoR) indicates that the increase of turbidity caused by WID remains close to the bed.
For modelling WID density currents rheological models are implemented in a 3D CFD (computational fluid dynamics) model TUDflow3D. With TUDflow3D the near-bed density current generated by a WID dredge can be simulated including the non-Newtonian flow aspect caused by the high concentration mud rheological behavior. The 3D CFD simulations can be used to optimize WID activities and to investigate where and how fast the near-bed WID density current will flow and where it will stop flowing.
