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 prevention of water logging. This study took Zhongshan and Zhuhai as subjects, proposed Copula-based design a calculated most practical solution drainage, waterlogging rainfall based on Kendall’s Return Period, providing references for construction such projects.
