| Abstract |
Non-structural improvements to urban drainage systems are necessary to overcome the elevated levels of urban flood damage. Thisstudy proposed a type of automatic pump/gate operation technology for urban pump stations that takes reservoir inflows and riverwater levels into account and its performance is compared with the current operation using the concept of residual flow-based resilience. The proposed automatic operation relies on three pump operations and two gate operations. The water depth at the monitoring nodewas used for the pump operation, and the monitoring node was selected in consideration of the first overflow node and the maximumoverflow node. The target area is the Daegu Bisan urban pump station, and the rainfall data consisted of probability rainfall sets withdurations of 30 minutes, 60 minutes, 90 minutes and 120 minutes, and frequencies of 30, 50, and 70 years. As a result of the applicationof the proposed operation, differences in the resilience between the automatic operation and the current operation were at least 5.20E-05with a maximum of 8.07E-04. The longer the duration is, the greater the difference in the resilience. |
