ABSTRACT

With the improvement of people's living standards, the demand for water security, environmental protection, and water ecology is becoming increasingly urgent. Under the background of building “happy rivers and lakes” as proposed by governments at all levels, it is necessary to consider the planning scheme of artificial water bodies from multiple angles and directions. Therefore, in the new era of urban construction, urban artificial water bodies are given new characteristics and functions. Therefore, this paper mainly analyzes the problems of flood control and drainage safety and ecological water use caused by the change in urban underlying surface and discusses how to further improve the role of urban water bodies in water security and water quality by establishing regional hydrodynamic and water quality models to simulate the effect of urban water body application on the above problems.
