| 摘 要： | 从实测资料出发,分析长江口北支近期岸线与主流线的变化,并就滩涂围垦对北支河势的影响进行深入探讨.认为目前北支航道500 t级船舶基本可以达到全潮通航,1 000 t级船舶乘潮保证率也可达90%,若采取一定的工程措施,对局部浅段进行疏浚和整治,早日开辟北支1 000 t级航道是可行的.

| Abstract: | The North Branch of theYangtze River estuary was historically the main channel of the Yangtze River to the sea.The channel has been depositing and gradually turning into a tide channel under the impact of natural stream evolution at the estuary and man-made blocking dams since 1950's.Due to the sediment deposition in the mid of 1990's,the channel has not been navigable.Currently only experienced mariners lead native boats through the channel during tide flow.Based on the surveyed data,the paper presents the... |
