Fuyang river system comprehensive control project includes Yinghe River Fenghuang wetland construction,in which emergent plants and submerged plants are arranged at Yinghe riverside beaches,forming the vegetation form of side beach vegetation.According to the analytical solutions for the velocity distribution of the double-layer vegetation at the beach simulating aquatic plants and submerged plants respectively which are verified by lab data,we find out the velocity distribution of the Yinghe river Fenghuang wetland.Combining with the results of velocity distribution,we verify the anti-scour design of the project and provide a method of beach vegetation flow of the ecological wetland design project.
