Abstract: The characteristics of sediment accumulation in Tokyo Bay are simulated by a multi-class sediment model in which the sediment particles are classified based on the cohesive characteristics and particle sizes. The model linking hydrodynamics, wind-induced wave and bed shear stress modules can account for sediment transport, settling, deposition and resuspension processes. Simulation results show the high correlation between the sediment accumulation and the local bed shear stresses. The erosion of accumulated sediment in shallow waters is influenced mainly by the strong winds, whereas that in deep waters is influenced mainly by the strong currents. Availability of information of classified sediment components dedicates the detailed simulation in various aspects, e.g., the simulation of cohesive sediment content in accumulated sediments and muddy-sandy level of bed materials. Simulation of current bed characteristics shows the disappearance of sandy bed compared with the field investigation in the past. One of the causes of this phenomenon might be due to the decrease in shallow waters of the elevation of the sandy bed as a result of coastal-zone development projects.
Description: Paper presented at The Seventh International Conference on HydroScience and Engineering (ICHE) hosted by the College of Engineering at Drexel Univeristy on September 10-13, 2006 in Philadelphia, Pennsylvania. The conference theme was IT in the Field of HydroSciences. It included several mini-symposia that emphasized IT topics in HydroSciences and the yearly meeting of the metadata group of the International Oceanographic Data and Information Exchange organization.
