Abstract
In low-lying districts of urban areas, drainage pumping stations were built to protect urban inundation by the heavy rain and, in the station, the pump operation is performed by only reservoir depth. But the effect of pump operation can be improved by various pump- ing rules. This study would like to analysis the reduction effects of urban inundation by early operation of pumps. The various design rainfall events were applied to Gasan 1 pumping station in Seoul and then, the most effective period of early operation was 10 min- utes. Also, the maximum water levels of reservoir simulated by early pump operation were 10~70 cm lower than results by the exist- ing operation rule and the overflow volumes in upstream sewer network were reduece by about 50%. Therefore, in urban areas, the flood control stability can be improved by efficient operation of the existing pumping station.
