Due to the unique location and fast development, the main threat to the disaster management in Shanghai is the flooding event, caused by the combination of heavy precipitation, storm surge and astronomical tide. Historical events show that the flooding concentrates in the flood season from June to October and it is not related to the flooding in Yangtze catchment. The natural causes of Shanghai flooding is typhoon, rainstorm and storm surge. The human causes is regarded as the land use and land cover changes, the urban heat island and land subsidence. The flooding events are complicated and can be classified in two types: rainstorm-caused flooding and storm surge-caused flooding. The rainstorm-flooding makes big waterlogging in city center and bring great economic losses and sometimes casualties in old residence. The storm surge-flooding can happen in the nearby area along Huangpu River or Coastline due to the over-topping or breaching of flood wall s. The c ity center on both sides of Huangpu River is still the most sensitive because of the high density of properties.
The stakeholder mapping shows that Shanghai Flood Control Headquarters (SFCH) is taking charge of the integrated flood management system. And actually Shanghai is establishing its more robust management system, including engineering and non-engineering system. Therefore, this thesis will further analyze some other examples around the world and give a recommendation table on flooding governance based on several flood management framework.
