套尔河是注入勃海湾西南岸的最大河流,河道内具有良好的水深条件,但因河口存在拦门浅滩,给河道及其两岸的开发利用造成了致命的障碍.本文综合实地勘测资料,对河口的动力地貌特性、浅滩成因与演变趋势等进行了分析研究,并通过河口潮流物模试验,确定了整治拦门浅滩航道的工程方案. It is the largest river to inject into the southwest coast of Bohai Bay, with good water depth conditions in the river channel, but the presence of shallow barricades in the estuary has caused a fatal obstacle to the development and utilization of the rivers and the two sides of the river.Based on the field investigation data, The dynamic geomorphological characteristics of the estuary, the causes and evolution of the shoal were analyzed and studied. Through the tidal current model test, the engineering scheme of rehabilitating the shoal shoals was determined.
