Abstract: With the rapid development of urbanization in China, urban waterlogging has become a significant problem in constructing the safety of the human environment. As an essential manifestation of the modernization of the urban governance system and capacity, the city physical examination establishes a multi-criteria evaluation system for problem diagnosis, rectification, and improvement. In order to accurately identify the risk of urban waterlogging, the concept of special physical examination of urban waterlogging risk was established, and the evaluation mechanism and indicator definition were improved on the basis of the “four-factor method” of flooding disaster assessment. From the perspective of urban basin flood control capacity, background disaster-bearing conditions, “Major-Minor-Micro” drainage system capacity, crucial locations and personnel protection, and emergency management capacity, twenty-four indicators in five categories were selected. The interaction between multiple factors is considered to establish a special physical examination indicator system as a characteristic evaluation mechanism of waterlogging with the goal of urban safety and resilience. The results of the study could provide theoretical and technical support for the diagnosis of urban waterlogging risk problems and the formulation of prevention and control strategies.
