沙质海岸河口航道回淤计算方法及其应用

从沙质海岸的水流泥沙运动基本理论出发，提出了沙质海岸河口泥沙回淤计算模式，推导出了适合闽江通海航道挖槽回淤计算的稚移质输沙率公式和悬移质回淤强度计算公式，利用该公式计算闽江口二期航道回淤的结果与实际情况一致。对闽江口深水航道回淤进行了预报计算。

Siltation Predication for Estural Navigation Channels on Sand Beaches

On the basis of basic sediment theory, a siltation calculation model is built, formulas of bed load transport rate and the intensity of suspended sediment siltation are derived, which are suitable for Mingjiang estuary. Navigation channel siltation for the second phase project at the entrance of the Minjiang river is calculated, and the results show a good agreement with real siltation. On this basis siltation prediction is made for water depth of the navigation channel at the entrance of the Minjiang River.
