Abstract: Global climate change and rapid urbanization had broken the original balance of urban precipitation, catchment and drainage, and worsened the urban flood problem in China, resulting in huge loss of life and property. Therefore, it is urgent to explore accurate and efficient urban flood forecasting approaches to strengthen urban flood prediction and mitigate impacts of this disaster.However, the complexity of urban meteorological and hydrological processes makes the study of real-time urban flood prediction face many challenges.Based on detailed reviews, this paper summarizes the main causes of frequent urban flooding in China, and elucidates progress in data and models for real-time urban flood prediction, with descriptions of existing problems and challenges, and future developments.

Key words: urban flood, real-time forecast, scenario simulation, meteorological hydrological coupling, multi-source data
