On the basis of sediment concentration field, the annual back silting intensity on the approach channel of 70000 DWT at Lianyungang Harbor was also simulated, and the calculated results was coincident with actual data.

• 鉴于进港航道回淤量是当地海域潮流、波浪、泥沙长期共同作用的结果，建议采用年平均含沙量场进行回淤计算，并在此基础上模拟了连云港7万吨级进港航道的年回淤强度，计算结果与实测资料吻合较好。
