Abstract: The problem of coping with river basin exceeding-design flood in China is prominent, and emergency and risk management are facing complex and severe situations and challenges under the influence of multiple changing environments, such as global climate change, human activities and engineering scheduling. Applying the theories of catastrophology, informatics, management science and other disciplines, the characteristics and management ideas of river basin exceeding-design flood risk are analysed by means of system analysis and theoretical derivation. The international advanced risk management experience and successful practice of emergency management are summarized. The sufficient, necessary and constraint conditions of river basin exceeding-design flood emergency management are analysed. The whole process risk management guarantee system of pre-disaster risk zoning, risk regulation and control in disaster and post-disaster risk compensation is constructed. The response mechanism of five-span coordination and the whole process integration of prevention, resistance and rescue, and the construction scheme of "flood control command sand table" are put forward, which realizes the quantification and visualization of response measures, risks and potential under different water conditions and the trade-off between "protection and abandonment" decision-making relationship. The research results provide theoretical support for the management and control of river basin exceeding-design flood.
