Abstract: In order to simultaneously simulate sediment resuspension caused by shipping and windinduced waves and currents, we have upgraded the sediment transport module of the PCFLOW3D model and used additional high-quality input data: (1) wave parameters were obtained using the SWAN model; and (2) bottom velocities due to shipping were calculated based on the Automatic Identification System data and added to the wind-induced bottom currents. The upgraded model enables short-term simulations of bottom shear stress and sediment resuspension due to combined effects of wind and navigation.
