摘要：
Based on the MIKE FLOOD platform, MIKE URBAN and MIKE 21 model were coupled to establish an urban waterlogging model. Taking Xinhua County in Hunan Province as an example, the typical regional drainage scenarios are simulated, and the results show that the model is suitable for urban waterlogging risk assessment and management. The evaluation results show that there are still some unreasonable pipe sections in the urban pipe network built in Xinhua County. Water is difficult to be discharged into Zijiang River or Huashan fishing ground immediately, which limits the overall drainage capacity of the old urban area, and some areas cannot meet the design and planning drainage standards. The main storage lakes and culverts in the city can meet the design standard of 20-year return period. Although the existing pumping station system can meet the needs of drainage, the corresponding treatment scheme is still needed for the five waterlogging prone points in the area. © 2021, Editorial Board of Water Resources Protection.
