| 摘 要： | 根据长江口南支下段新浏河沙、新浏河沙包、宝山南、北水道的形成发育过程分析,落潮流北偏,河道放宽率较大、沉积物抗冲性差以及丰富的物质来源是形成浏河口外主槽内浅滩沙洲的主要原因.在落潮流控制下,新浏河沙、新浏河沙包以125°方向朝下游移动.自2004年以来,新浏河沙包北冲南淤趋势加剧,增加了南、北港分流口河段的不稳定性,为确保宝山南、北水道10m以上水深,对新浏河沙包实施动态治理.

| Abstract: | Evolutions of Xinliuhe sand shoal and sub-Xinliuhe sand shoal and Baoshan south and north waterway at the lower parts of the south branch of the Changjiang Estuary were studied.The results suggest that main factors controlling development of the sand shoals in the main channel of Liuhe river mouth be the shift of ebb tidal currents northwards,the larger widening ratio of river channel compared with those of the upper and lower parts of the south branch,and the abundant supply of sediments from the Baimao an... |
