Abstract
Urban flooding due to rapid urbanization has recently become frequent. In this study, a hydraulic model experiment was conducted on Shinwol rainwater storage and drainage system constructed for the first time in South Korea to prevent urban flooding. Experiments were preformed for 55 scenarios, of which 19 overflows occurred. In addition, the video analysis for the scenarios where the overflow occurred showd that the overflow occurred during the process of exhausting the pressurized air in the facility and the undular bore were moving. Results of this study, it was judge that it would be advantageous to maintain a completely drained or full-pipe condition for stable operation of the Shinwol rainwater storage and drainage system for continuous rainfall in the future. And it is necessary to additional research on the correlation for the magnitude of inflow discharge, overflow and undular bore.
