Modeling and analyzing of waterlogging in typical urban area

With the acceleration of urbanization, urban waterlogging has become a difficult problem, which restricts the sustainable development and urbanization in China. This paper evaluates, analyzes and summarizes the current waterlogging research in China from three aspects: waterlogging control standards, waterlogging control models and methods, and current research difficulties. We take the Jiangbei District, Fuzhou City as an example. A waterlogging model was established to obtain the stage hydrographs and design flood flow, comprehensively evaluating the waterlogging situation and the comprehensive waterlogging prevention capacity. The results show that, accurate waterlogging simulation plays an important role in the construction of urban waterlogging prevention. While addressing the existing controllable difficulties, the research on urban waterlogging in China should actively work on coping strategies for uncontrollable difficulties, and enhance the ability of the regional waterlogging management system to deal with various extreme weather conditions and human activities.
