In recent years

China's urbanization process has slowed down

extreme high temperature and rainstorm weather events have increased and intensified

urban infrastructure construction has lagged behind and lost the support of “land finance” dividends

urban flood prevention is facing the dual pressure of reducing risks and restructuring balance

and it is urgent to explore the way to improve the overall planning and resilience of river basins in transition to high-quality balanced development under the guidance of the concept of ecological civilization. Based on the investigation and analysis of major typical flood disasters and the comparative study of flood management concepts and practices between China and foreign countries

this article elaborates on the basic characteristics and evolution laws of urban flood risks under changing environments from the perspectives of disaster science and disaster prevention

explores how to build an urban flood prevention and control system

risk management model

comprehensive water control strategy

and resilience enhancement strategy that are compatible with the development needs of the new era. The discussion in this article helps to enhance the ability to foresee the evolution prospects of urban flood risks

the overall planning ability of the integrated flood prevention and control system between urban and rural areas in the basin

and the resilience response ability to classify and handle flood disasters and turn harm into benefit.
