The paper introduces a coupling model to optimize flood mitigation of detention basin facilities. A flood routing simulation software (EPA-SWMM) is integrated with an evolutional optimizer (EPSO) for searching optimal side-weir height and pumping schedule. The optimum design and operation are applied to an urban case study in Seoul, Korea, for historical severe flooding event in 2010. The performance of the optimal facilities show the effectiveness comparing to present facilities in terms of flood damage reduction both downstream and in the detention reservoir area. Specifically, the peak water level at the detention pond under optimal conditions is significantly smaller than that of the current conditions. The comparison of the total flooded volume in the whole watershed shows dramatic reduction of 79% in severe flooding event in 2010. |
