It is not easy to predict sedimentation by numerical simulation for channel and port area situated along river mouth to costal area especially because of complex behavior of advection-diffusion of siltation by waves and flow, and drift sand at shallow area by waves. Therefore, in this research, studies of channel sedimentation such as the relationship between turbidity and external forces, changes of sedimentation trend with varies of location as river mouth area and channel area, and seasonal effect to the sedimentation etc. were carried by long-term bathymetric surveys and field monitoring such as wave, current and turbidity at -14m channel dredging site. As the results, significant increase of turbidity and sedimentation in the channel was occurred during rainy season with frequent high waves. Therefore, dominant effect to sedimentation in this channel was suggested as waves by this study results.
