Objectives of the study
Affected by global climate change and human activities, in recent years, extreme weather and urban waterlogging events have occurred frequently in China, with floods, droughts, and salt tides overlapping and coexisting. The defense situation is extremely complex, especially the significant casualties and property losses caused by the 7.21 and 7.20 floods in Beijing and Zhengzhou, which have exposed serious deficiencies in urban safety resilience in China at present. How should we build and repair our city in order to make it indestructible, stable in disasters, and protect our lives and property safety? By clarifying the characteristics and trends of flood disasters in changing environments, we can formulate flood prevention and control strategies tailored to local conditions and enhance urban resilience.
