MODELLING OF SEDIMENT RESUSPENSION IN THE NEVA BAY
A three-dimensional numerical model of the Neva Bay was extended by adding new modules for computation of wave parameters and suspended sediment concentra- tion. The bottom of the Neva Bay was divided into areas with predominance of either sand or silt sediments with different particles' characteristics. Sensitivity analysis of the choice of the critical bottom shear stress is carried out. The results obtained are com- pared with turbidity measurements in the Neva Bay.
