Urban rivers in mountain areas generally have the characteristics of large runoff season variability, large rainfall and the like, and often cause the problems of high flood prevention risk in flood season, poor water quality in early rainfall period and the like. The aim of purifying water quality and creating landscape is the aim pursued by numerous designers and scholars, besides the functions of retaining, flood management, flood drainage and downstream protection of the traditional engineering is achieved. Any single traditional hydraulic building cannot meet the requirements at the same time, and the problem needs to be solved efficiently and at low cost by developing a superposition combination of multiple types of hydraulic buildings.

At present, the urban ecological landscape dam is commonly constructed by a plurality of types such as a sluice, a rubber dam, a steel gate dam and the like.
