This paper studies the river bed evolution, the layout plan of Chaotou diversion dike and its protective measures by means of data collection and consolidation, integrated bed fixing and dynamic bed physical model as well as general technical means of generalized tank test. The structural type and other key issues. Collecting and collecting the information of terrain, sediment and sediment of Baguazhoudao section for many years and clarifying the existing problems of the section of the river and its treatment ideas. The physical model of river bed fixing work of Bagua Chau Road was established and the plan of layout of Chaotou diversion dike was studied. Established the whole Bagua Chau Road section of the movable bed river physical model, the study of the first head diversion dike after the implementation of local
