It is thought that the channel bay line evolution processes can be divided into four stages. The first stage is soon of the sea level stable when the bayhead mountines are eroded and developed abrasion geomorphy and the productive materials were transport into the bay deposition by the tidal current and wave current and were reworked into gravel dams. The second stage is characterized by the fluvial output sediments and eroded sediments mixed deposition in channel bay and developed marine accumulation plain and sand riges in the plain under the wave reworked. The third stage developed clay silt marine accumulation plain under the action of the channel current and the wave action is very limited. The fourth stage is marked by human being reclaim which result in the channel bay filled and evoluted into a strait arce coast.
文章认为，峡道海湾的充填经历了四个阶段，第一阶段以峡道海湾湾顶山体在波浪作用下产生的侵蚀物质充填为主，发育了海蚀崖、海蚀洞、海蚀穴等侵蚀地形和湾顶砂砾石堤等堆积地形交替的峡道湾顶地貌，第二阶段以河流输出物质和峡道湾岛屿、礁石侵蚀物质在潮流作用下向峡道湾输运，由潮流和波流共同沉积为特征，发育海积平原，部分粗颗粒泥沙在波浪的改造峡，发育平原沙堤，第三阶段以河流输出物质为主，在涨落潮流搬运下进入峡道和峡道湾沉积，在峡道湾中发育以淤泥质粉砂为主要物质的海积平原，第四阶段以人类围涂造田为标志，加速峡道湾的充填过程，使峡道海湾最终趋于夷平，形成顺直均衡的弧形海岸。

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。
