At a port located at the estuary in Japan, 800,000 m3/year of sediment is accumulated annually in navigation channel and basin. In order to consider effective countermeasures, it is necessary to elucidate sediment dynamics due to waves and tidal currents of the target port. Therefore, we are conducting a field observation of sediment transport and deposition. In addition, we have developed a numerical simulation model based on the results of the field survey for evaluated the countermeasure against the port sedimentation. We introduce the knowledge about sediment transport obtained through multiple operations.
