| Abstract: | According to the observed hydrological data and the bathymetric charts,the siltation characteristics of navigation channel in the Oujiang estuary were analyzed in this paper.The results show that tide in the engineering sea area is normal semidiurnal tide with average tidal range over 4 m,and the tide is strong in this area.Tidal current in the engineering sea area belongs to shallow sea abnormal semidiurnal tide current and assumes to-and-fro current.The sea bed generally remains stable with little erosion and deposition.The siltation of the navigation channel in the Oujiang estuary mainly occurs during flood discharge and typhoon,that is,the sudden siltation,while there is little sedimentation during other times. |
