Prof. LI Junqi’s team examines the challenges and barriers faced in building resilient cities, as well as the current state of resilience construction in China amidst global flooding issues. By analyzing the impact factors of urban flooding, a comprehensive urban flood resilience evaluation model is proposed, comprising spatial resilience, engineering resilience, and management resilience. Previous studies have not closely integrated the influencing factors with the flood disaster process. The CRITIC assignment method takes into account the correlation between the indicators while objectively considering the magnitude of the differences between them. Therefore, this paper adopts the CRITIC assignment method to categorize and integrate the evaluating factors, aiming to enhance the overall resilience to urban floods. The flood resilience evaluation factors are reassessed in this study to ensure that the various systems and segments of the city can prevent, effectively respond to, and efficiently recover from flood disasters while achieving sustainable development. The findings of this research have been published in the journal Water-Energy Nexus under the title “Urban spatial, engineering and management resilience capacity enhancement from a flood safety perspective”.

Title and authors

The research shows that In the process of preparing the construction program for a resilient city, it is important to consider the research of the target system, the construction of the technical system, and the improvement of the management system. This paper utilizes the CRITIC assignment method to closely examine the relationship between urban characteristics and flood disaster processes. It ultimately develops a flood resilience risk assessment index framework with eight evaluation indicators. The framework provides a scientific foundation for implementing flood resilience enhancement measures across these three dimensions. Spatial resilience, engineering resilience, and managing resilience, along with other collaborative flood prevention and comprehensive management methods, can effectively address both the symptoms and root causes of flood disasters. This comprehensive evaluation method ensures the overall coordination of spatial, engineering, and management resilience, providing multi-dimensional support for the construction of disaster-resilient cities.
