Waterlogging Risk Assessment and Analysis Based on InfoWorks ICM
Based on InfoWorks ICM,a 1D and 2D coupled waterlogging and drainage model of a new district in Zhejiang Province was constructed.The drainage capacity and waterlogging risk of the pipeline network in the study area were analyzed and evaluated according to the simulated load state of the pipeline network,the depth of ground water and the time of ground water in the study area.The drainage capacity of the current pipe network system in the study area has not reached the design standard of once-in-3-years drainage,and the drainage capacity of the pipe network is mostly below 0.5 once-in-a-year.There are high risk areas of waterlogging under a 20-year design rainstorm,and the waterlogging risk areas mainly occur in areas where the underlying surface is hard,the terrain is low,the pipe network is missing and the pipe diameter is small.It is suggested to improve the drainage pipe network system in the blank area of the study area,and to reform the pipe network that does not meet the design standard.
