Research On Stormwater Management Of Urban Parks Based On SWMM Model

There are many urban problems in the process of urban construction,including the stormwater management problem.And the construction of urban park stormwater management can promote the solution of urban stormwater,which conforms to the direction of sustainable urban development and improves the urban ecological environment.Nowadays the construction of stormwater management in urban parks becomes a new research direction of landscape architecture.The application of low impact development technology into urban parks might solve the problem of urban water security and improve the urban ecological environment.Firstly,this paper combs the theory of stormwater management and the technical measures of low impact development facilities,and summarizes the achievements of stormwater management in urban parks at home and abroad.In order to solve the problem of stormwater problem in urban parks more scientifically,SWMM is applied to realize the quantitative analysis of stormwater management in urban parks and assist the design of stormwater management in the parks.This paper clarifies the operation principle of SWMM model,explores the parameter setting of the model simulating stormwater runoff,and combs the construction process of SWMM model simulating hydrological situation in the urban parks.At the same time,this paper refers to the excellent cases at home and abroad that alleviate the stormwater problem in urban parks,and sorts out the planning concept of excellent cases and the specific solutions of stormwater management.Taking Mengzhou ecological park as an example,the design reasonably arranges various low impact development facilities to meet the requirements of stormwater management in the park.The design of the park complies with the park design specifications and excavates Mengzhou regional culture,so as to build a park with beautiful landscape,rich cultural atmosphere and significant ecological benefits.The SWMM model is used to simulate and verify the design of sponge system in Mengzhou ecological park through quantitatively analyzing the reduction of the park's stormwater runoff and the reduction of stormwater pollutants.Through visualizing the evaluation results of stormwater management in Mengzhou ecological park,the design of the stormwater management system can be improved effectively.
