| Abstract: | Based on the refraction diffraction combined numerical model of random wave in tidal current field under the condition appropriate to a mild topography on a large range,the shallow water current equations under the effect of waves and the suspended sediment diffusion equation with interactions of wave and tide current, the 2 dimensional sediment mathematical model with interactions of wave and tide current has been set up.This model in the northern sea zone of the Bohai Gulf is utilized to carry out the numerical simulations of the dredged materials' suspended sediment diffusion,transport and the evolution process of sea bed. The results are satisfactory,which have had reliable and scientific bases for engineering organization to make a decision. |
