摘要：
To explore the influence of sea level rise on sediment deposition in the Yangtze Estuary Deep-water Navigation Channel, this article has simulated the change of flow velocity in North Passage in different situations of sea level rise with MIKE21 FM and calculated the threshold motion velocity of sediment in North Passage. The results show that as sea level rise, flooding and precipitating velocities in upside North Passage increase and in middle North Passage decrease. Precipitating velocities in middle North Passage are greater than threshold motion velocities of sediment and sediment is scoured easily. When precipitating the middle of North Passage is in the washed state and it is beneficial to the construction and maintenance of the Deep-water Navigation Channel in North Passage.
