Study on Copula-based Coordination of Urban Drainage system and Sewage system Design

The urban drainage system is co-regulated by various governmental departments, who adopt different standards in designing the system, an attempt not conducive to the prevention of water logging. This study took Zhongshan and Zhuhai as the subjects, proposed the Copula-based design of a drainage system, and calculated the most practical solution to drainage, waterlogging and rainfall based on Kendall’s Return Period, providing references for construction of such projects.
