| 摘 要： | 把长江口北槽深水航道内2012年洪枯季两次、大中小潮的观测资料以及对应时段的航道回淤量等实测数据，引入到常用的近底层泥沙通量计算模型中，通过选取和率定其中主要的模型计算参数以及率定人工维护条件下航道内底层泥沙的沉降概率，最终建立了一个适合长江口北槽深水航道回淤量计算的数值模型，并利用洪枯季航道回淤的实测资料对该计算模型进行验证，得到较符合的结果。

| Abstract: | This paper focuses on the relationship between the movement characteristics of flow(and suspended sediment)and erosion(and deposition)near bottom in the deep navigation channel of the north passage in the Yangtze estuary. Based on the model for calculating the sediment flux near the bottom and observation data,the key parameters,such as the settling velocity and settling probability of sediment,are selected and calibrated. Eventually the calculation model for back-siltation in the deep navigation channel of the north passage is established and discussed. The calculated results by this model fit well the measured data. |
