The Yangshan deepwater harbor locates in the Qiqu Archipelago with many islands and tidal channels. The cyclic tidal flow with strong velocity of 1.0m/s is the major dynamic force for maintaining the stability of the way and the sediment in flow is always under the combining action of waves and tidal currents. The seabed evolution is aroused by suspended sediment transport. The suspended sediment concentration is more 1.0 kg/m3. Based on the measured data of Oct. 1996, 1999, 2004 and 2006, and the measured surface suspended sediment concentration data from 1998 to 2007, the change characteristic of suspended sediment concentration was analyzed. Moreover, it was discussed to the causes of the variation of suspended sediment concentration, 〖JP2〗the effect of suspended sediment diffusion of Changjiang river mouth to Yangshan, and the “channel effect” to high suspended sediment concentration in Yangshan sea areas.
