Abstract: Under the impact of climate change and human activities, urban flooding/waterlogging is becom⁃
ing serious in China year by year. Based on the study of urban hydrological cycle,hydrological and hydro⁃
dynamic models for the simulation of urban flooding/waterlogging processes should be developed. This kind
of model is a very important tool for the understanding of urban flooding/waterlogging mechanism, mitiga⁃
tion of flooding/waterlogging disaster and assessment of the mitigation effect of disaster for the sponge city
construction. In this paper, urban flooding/waterlogging and sponge city construction in China is reviewed,
and the principle for urban flooding/waterlogging simulation is analyzed. Hydrological models, hydrodynamic
models and coupled hydrological-hydrodynamic models are reviewed,and the widely used urban flooding/wa⁃
terlogging models are summarized. Then, hotspots related to urban flooding/waterlogging simulation are pre⁃
sented,and future prospects are investigated.
Keywords:urban flooding/waterlogging simulation;hydrological hydrodynamic model;integrated urban water
system;flooding/waterlogging forecasting and operation;smart water
