【Background】 Floodplain is the ecological cradle of alluvial rive to provide a buffer to flooding. Rivers naturally function to transport runoff and sediment, making the river have the double section characteristics of river trough and beach to meet the needs of water and sediment transportation in different periods. There are also villages in the floodplain of many rivers. There will inevitably be some contradictions between the needs of human activities (such as agricultural irrigation, transportation and social development) and river functions (ecology, flood and sediment transportation). If there is no scientific coordination between the two aspects, it will lead to mutual restriction affecting the ecological health of the river as well as the Sustainable high-quality development of the beach area society. It has become an important challenge for river managers to plan traffic routes in wide floodplain areas with less environmental impact. In order to implement the protection of river health in river proj
