Urban Drainage System Design Based on Combination of Storage Regulation Algorithms and SWMM Model——A Case Study of Flood Control System in Zhengpu Port New District,Ma'anshan
This study takes the drainage system of Zhengpu Port New District in Ma´anshan as a representative case to explore the application of urban drainage system design based on the combination of storage algorithms and SWMM models.Established in 2012,Zhengpu Port New District is positioned as a modern port logistics area,a modern port industrial area,and an integrated urban area,with an important strategic development function.Firstly,the study collects geographical,climatic,and drainage system data of the new district and applies storage al-gorithms based on water balance to analyze the drainage system and its scale.Then,the optimized plan is applied to the SWMM model for dy-namic simulation and analysis of rainwater runoff processes.The research shows that to achieve the flood control design standard of no water accumulation in a 20-year rainstorm,the study area needs an external drainage pump station with a total design flow rate of 111.9 m3/s.After deducting the total flow rate of the existing three pump stations,an additional 30.5 m3/s of external drainage flow rate is required.The results of this study provide a scientific basis for drainage and disaster reduction and drainage system renovation in the northern part of Laoxia River in Zhengpu Port New District,contributing to the development and people´s livelihood of the new district.Meanwhile,this research method can serve as a reference for urban drainage system design application studies based on the combination of storage algorithms and SWMM mod-els,promoting the development of urban drainage system design.
