There are two types of sewer systems in urban drainage systems: combined and separated. The waste water and the runoff caused by rain are drained in a single tunnel or pipe in the combined sewer systems; while the separated sewer systems use two separate systems of tunnels or pipes to drain waste water and runoff respectively. It has been indicated by many researchers that the performance of the sewer systems often can not reach its designed capacity when rainfall with larger return periods occurs. In the developed nations, real time control sewer systems are therefore applied to make the sewer systems more efficient for inundation caused by heavy rainfalls. The main objective of the research is to simulate the performance (e.g. reduction of the total overflow volume in the drainage system) of the current drainage systems under optimized gate operations without extra capacity imposed to them. This research uses the Zhongang, Shijian, and Baoyi drainage systems of the 4th drainage area of Taipei City to demonstrate the effectiveness of applying real-time control (RTC) in Taiwan’s urban drainage systems. For the purpose of RTC simulation, the multi-thread technology is employed to integrate the Storm Water Management Model (SWMM), developed by US EPA, and a genetic algorithm library, called GAlib, to simulate RTC in the case study areas. The simulated results show: (1) total overflow volume in each pumping system which gates are installed in the manholes reduced under optimized gate operations. (2) These pumping systems with gates installation connected by pumps reduced the total overflow volume under optimized operations.application/pdf720679 bytesapplication/pdfzh-TW國立臺灣大學土木工程學系暨研究所都市下水道系統即時控制基因演算法多執行緒urban drainage systemsreal-time controlSWMMgenetic algorithmsMultithread[SDGs]SDG11reporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/2894/1/932211E002041.pdf
