滨江船厂出港航道水文泥沙条件分析

Analysis of hydrological and Sediment Conditions in the Exit Channel of Binjiang Shipyard

通过对倒套区的泥沙来源、江床底质分布、含沙量变化规律以及潮流输沙分析认为，受地形影响倒套区产生的潮汐往复流，是倒套赖以生存的条件。从水动力特性的分析，倒套区无底沙输移，对维持航道水深有利。

By analyzing the source of sediment in the shaped meanderingchannel, distribution of bottom sediment, laws of sediment concentration variation andsediment load -transported by tidal now, a conclusion is drawn that the reciprocating tidalflow affected by the topography is the main factor that keeps the Ωshaped meanderingchannel stable for a long time. Based on the analysis of hydrodynamic characteristics, itcan bee seen that there is little bed load transport in the region, and that partial suspendedload may be carried out by the ebb-tide flow, which is favorable to maintaining the depthof channel.
