Effect of Waves in the Transport and Diffusion of Dredging Soil

  This study is to investigate the effect of wave in the transport and diffusion of dredging soil by considering the interactive action between tidal current and wave for the prediction of the transport and diffusion process of dredging soil. Mike21, which is known as a commercial software, is used as an numerical model and nearshore wind wave model is selected to estimate wave field. It is found through the investigation, which has been made from an numerical simulation of the construction of Busan new port, that the dredging soil under the interactive action between tidal current and wave is more transported and diffused relatively to the wider extent than one without wave action. It seems to be the reason why the sediment transpoted to the open sea is resuspended and diffused again by the wave action.
