The deepening of channel and basin causes the increase of sedimentation in the channel and basin. On the other hands, the prediction of sedimentation by numerical simulation situated along river mouth to costal area is difficult due to complex behavior such as inflow from river, advection-diffusion of suspended load by flow, and bed load by waves. In this research, the estimation of sedimentation characteristics after deepening the channel and basin of Lach Huyen Port were carried out based on the long-term field monitoring after the completion of dredging works. The reproducibility of sedimentation in the site was also verified by numerical simulation considering the estimated characteristics.
As the result, the differences of sedimentation trend were confirmed depending on the relationship between river discharge and waves, and the sedimentation trend was reproduced well by the numerical simulation considering the relationship.
