This study investigated bathymetry changes and its causes in the access channel and basin of Kanazawa Port, which is suffering sedimentation, by analyzing field data of wave, current, sediment size and bathymetry. The results showed that the amount of the sedimentation is 168,000 m3/yr and that sands and silts transported by south-westward currents during storms and long-period oscillations inside the port cause the sedimentation. The numerical simulation model incorporating those sediment movements has well predicted the bathymetry change in the channel and basin.
