There are two sewer systems in urban drainage systems: combined and separated. The waste and runoff caused by rain are drained in a single tunnel or pipe in the combined sewer systems. However, the separated sewer system uses a different kind of tunnel or pipe to drain waste water and runoff. It is indicated by many researches that the performance of the sewer systems would not reach its designed capacity when rainfall with larger return periods occurs. In developed nations, real time control sewer systems are widely applied to anticipate the probability of inundation caused by heavy rainfall. The related researches of real time control in urban drainage systems are rarely referenced. Despite the integration of water resources engineering researches, the decision support systems with real time control in urban drainage systems are still seldom found. The main purposes of this research are: (i) construct a real time control system that provides real time control strategies for decision makers. (ii) Construct a decision support system that incorporate the urban real time control drainage system to the contribution in research and applied engineering.下水道系統即時控制支援決策系統sewer systemsreal time controldecision support system
