Abstract

This study presents the modeling for the formation and characteristics of sediment layer in Tokyo bay over the time scale of several years. The model includes hydrodynamics, wave, bed shear stress and multi-class sediment models in order to simulate the sediment processes both in water body and bed layer. The sediment model accounts for sediment transport, settling, deposition, resuspension and burial sedimentation processes and is able to reproduce the accumulation of bed sediments. By the concept of multi-class particles, the important information of bed layer characteristics, for instance, the spatial distribution of particle sizes and the water content ratio are provided. Moreover, the numerical experiment was carried out to describe the mechanism of sediment accumulation investigated in the field.
