长江口南港北槽风暴回淤统计模型
A Statistical Model of Storm-induced Deposition in the North Passage,Yangtze Estuary
-
摘要: 作者通过对影响长江口南港北槽风暴回淤主要因子的分析比较，改进并优化了北槽航槽原有的风暴回淤强度公式，提出了用台风过程、风区长度、航槽两侧6m等深线跨度与潮差表示的航槽回淤计量公式，经9430、9711号等台风后报检验，该提出的北槽航槽回淤计量公式与实际有较好的一致。Abstract: By the analyses of main factors affecting storm-induced deposition in the North Passage,Yangtze Estuary, the previous storm-induced deposition formula has been improved,and a new formula has been presented in terms of the intensity and path of typhoon, the evolution tendency of local bedform and the tidal state.The handcast verification by use of No.9430 typhoon and No.9711 typhoon prove the calculated results from the new formula are in well agreement with the filed data.
