- Abstract:
- The combination of “storage & discharge” is an essential measure to handle the looming pluvial flood risks in Chinese cities. Therefore, how to quantify the required urban storage capacity becomes the priority for the implementation of “storage & discharge” strategy. This paper summarizes storage capacity calculation methods from urban planning of three countries, and compares them with the relevant Chinese standard and guidelines. The applicability of these methods is then assessed in the context of resilient pluvial flood protection planning.The result shows that the Dutch UWBM-SDF method aligns the principle in the Chinese standard of pluvial flooding prevention, which requires a city free of pluvial flood events under certain return period. UWBM-SDF can facilitate the quantification of long?term overall required storage capacity, and it has been applied in two Chinese case studies. In the end, the paper provides the future research direction towards the quantification method of storage capacity which fit the requirements of pluvial flood protection in Chinese cities.
