- Abstract:
- Guangzhou is located in the subtropical marine monsoon climate zone, which has the rainfall characteristics of high intensity, time concentration and high frequency due to special geographical location. A new emergency management model has been proposed based on the problems in waterlogging emergency management of urban drainage system to effectively deal with the impact of rainstorm and waterlogging on citizens’ lives and urban economic development. This model is optimized and innovated from the aspects of emergency command and dispatching system, early warning plan system, emergency deployment system and assessment and regulation of the waterlogging points after flood, which can build a huge city drainage security system with more tenacity. Guangzhou has effectively dealt with urban waterlogging caused by extreme weather through this model, such as super typhoon “Shanzhu”, “5·22 heavy rain”, historic “Dragon Boat Water”, astronomical spring tide, and achieved remarkable results in waterlogging prevention and control.
