Research on the compatibility and connection between urban municipal drainage and hydraulic flood control and drainage standards
Flood disaster occurring frequently in urban cities during flood season has affected the lives of residents,and has been widely concerned by society in recent years.A seemingly simple drainage problem is actually a compatibility and con-nection problem between municipal drainage and water conservancy flood control and drainage standards.Taking Kunshan City in Jiangsu Province and Cixi City in Zhejiang Province as typical objects,this article deeply analyzes the three ele-ments of design rainstorm,runoff flow and discharge water level under the two system standards,and puts forward the com-patibility connection method of each element under the two system standards.Furthermore,it also construct compatibility measures for flood prevention and control in Cixi,and evaluates the significant reduction of waterlogging risk after the implementation of the measures based on a refined coupling flood model between the pipeline network and the river net-work.The research results contribute to the construction of a compatible and coordinated municipal drainage and flood con-trol system,and are helpful to urban waterlogging management.
