Recently, floods have caused many disasters in worldwide cities due to frequent heavy rainfall and hydrological events resulting from extreme climate.The frequency of short-duration heavy rainfall increases, resulting in increased floods. Thus, the original stormwater drainage systems are overloaded and should be upgraded their drainage capacity. This study focuses on the design of stormwater drainage system inlets to investigate the impact of drainage capacity based on experimental and numerical analyses.
To reduce flooding disasters and their impacts due to overloaded stormwater drainage systems caused by heavy rainfall., in addition to engineering methods as countermeasures, non-engineering methods for disaster prevention and response must be able to update information in real-time and accurately for decisionmakers to make subsequent decisions. Therefore, it is important to develop relevant technologies such as the hydraulic parameters of hydraulic structures, including inlets, side ditches, catch basins, and connecting pipes, in the stormwater drainage systems combined with rapid flooding simulation technology that can immediately reflect surface hydrology and hydraulics. Realtime simulation of conducting stormwater drainage systems and flooding simulation systems can provide quantitative evaluation for the operation of flood control facilities, thereby improving flood disaster analysis and emergency decision-making capabilities, and is expected to reduce disasters and losses of life and property. The present project performs drain inlet experiments to discover essential factors for drain inlets. Real-time urban flooding evaluation is then conducted to find the practical ranges and settings of these parameters in Taiwan’s urban areas.
