Abstract
A FEM-based 3D suspended sediment transport model under development for the radionuclide transport modeling in the Yellow and East China Seas was described with preliminary results in the 2013 workshop at Qingdao. The circulation model was driven by external forcing terms including wind and heat flux at the sea surface as well as tide and oceanic inflow-outflow at the open boundaries. The suspended sediment module was extended to deal with the mixture of cohesive and non-cohesive sediments by introducing the parameter of critical cohesive sediment fraction in the bed as done by van Ledden (2003). The model run continued only over a year. As a sequel to 2013 presentation, we present in this talk the refined model results with wave effects. For simulating wave parameters, we have used a spectral wave model WWM-II. A total of five year model runs have been performed with emphasis on the model validation. Comparison of computed and measured waves at Ieodo is described. The computed results are found to be in good agreement with the GOCI images and, after converting, turbidity measurements by Bian et al (2013). driven by external forcing terms including wind and heat flux at the sea surface as well as tide and oceanic inflow-outflow at the open boundaries.
