This study uses web-based information to explore the spatial and temporal trends of reported city flood events for all mainland China cities from 1984 to 2015. Panel data were compiled on flooding (or the lack thereof) within China’s cities for every year in this period, and the relationship between the annual number of cities with reported flood events and possible influencing variables was analyzed. Few cities experienced flood events before 2001, but this situation then increased dramatically after 2010. In 2015, approximately 60% of China’s cities experienced a storm-flood event, which is three times as many as the government estimated in 2011.
