Sediment from river is not the main source of the Rushan Bay now any more ,which leads to the change of balance of sedimentation power. Sediment will transport because of the drive of hydrodynamic elements in macroscopic view .Direction of suspended load is basicly the same as tidal current .Flood tide makes suspended load transport to tip of the inner Bay and to the Mouth in exterior Bay .The direction of longside sediment transport in two sides of the Mouth mainly focus in the Mouth .Because the coastline along the exterior Bay is very meandering and it belongs to the type of bedrock ,besides some sediment going into the inner Bay ,so actual net sediment discharge rate is less than calculation .It develops an ebb delta out of the Mouth and forms tidal sand ridge ,tidal washing canal ,barrier bar and marine physiognomy ;The result of model simulation disclosures that differences of sediment erosion and siltation between single tidal action and wave-current action are very big .From the analysis of sediment composition、sediment sources and stability of beach and ridge ,this article gets the conclusion that the channel has the possibility to silt ,though the course maybe very slow.

通过分析研究文章得出如下结论:沉积物平面分布与水动力的时空变化存在很好的相关性;口门外发育落潮流三角洲,形成潮流沙脊、潮流冲刷槽、浅滩、拦门沙等水下动力地貌;乳山湾河流来沙已不是湾内泥沙主要来源导致沉积水动力平衡发生改变,宏观上表现在泥沙受水动力驱动发生不断运移;悬沙运移方向与涨潮流方向基本一致,湾内涨潮流带来的悬移质泥沙向湾顶运移,湾外悬移质泥沙主要向口门方向运移;湾口两侧岸段沿岸输沙方向均指向口门方向,由于乳山湾外海岸线曲折,两侧岸段以基岩为主,加之部分泥沙进入湾内,实际净输沙量小于计算值;数值模拟发现潮流单独作用与波流共同作用下泥沙蚀淤模拟差别较大;从沉积物组成、泥沙来源及滩槽稳定性三个方面分析,文章认为研究区存在航道淤积的可能性,但过程相对较慢。
