Abstract: Urbanization with the decrease of pervious area combining with climate change impacts has caused more flooding in the urban area. To dispose of flooded water, detention basins have been considered as one of the most effective measures. Recently, applying meta-heuristic algorithms to optimize layout and design of the detention system is well documented in literature focusing on flood reduction for the whole watershed. In fact, the urban area is flooded at many sites in extreme storm events and the overall optimizing approach may not satisfy for all inundation places. In this paper, a decentralized approach is proposed to analyze flood damages in the urban area. A controlled node network is proposed to comprehensively represent the effects of detention reservoir system. Instead of minimizing the total flooded volume, present study searches the optimal design of detention reservoir system to minimize flood peak at multiple locations. The proposed approach is verified by comparison with another optimization approach and current system design. The new detention design outperforms in terms of flooding mitigation and construction cost as well
