The Urban Storm Flood (USF) has a higher frequency and is affected by global climate change and urbanization. The difficulty of rainstorm forecast and great harmfulness of urban flood disaster have been goten great attention and wide public concern, which makes it a research focus in the field of urban flood control and disaster reduction areas. Taking the USF under changing environment as research object, the paper reviewed the domestic and abroad research processes from four aspects such as simulation, characteristics, formation mechanism and response management.The paper pointed out some existing problems and prospected the future research,and proposed research idea which focuses on the characteristics and response mechanism of the USF under changing environment. This study should be beneficial to scientificly understand the USF and improve the rapid response ability to USF and reduce disaster loss of storm flood.
