Abstract

An urban drainage system consists of two major systems : flood drainage facilities and operating practices. The facilities are composed of sewer networks, gates, and pumping stations and the operating practice consists of pump or gate operation. Then, a real time simulation system which is able to simulate urban runoff and the pump operation and to consider the backwater effect is required to operate efficiently the pump. With this system, the efficient pump operating rule can be developed to diminish the possible flood damage on urban areas. In this study, a real time simulation system was developed using the SWMM 5.0 DLL and Visual Basic 6.0 equipped with EXCEL. Also, for developing efficient pump operating Rules, two new Rules were suggested. The first Rule is designed to operate pumps considering the condition of sewer networks such as depths of each junction. The second is to discharge all the amount of inflow at each time step. Results obtained by those Rules were compared with one by the current pump operating Rule which is able to consider only the depth of the retard basin. The developed model was applied to Joonggok retard basin and verified their applicability.

일반적인 도시 내배수시스템은 시설물과 운영방법으로 구분된다. 시설물은 관거, 수문, 배수펌프장 등으로 구성되며 운영방법은 펌프 및 수문운영으로 구성된다. 이러한 내배수시스템에서 유역의 유출 및 펌프 운영을 실시간으로 모의하고 배수효과를 고려할 수 있는 운영 모형은 펌프를 효과적으로 운영하기 위하여 필요하며, 이러한 실시간 운영 모형을 통하여 도시유역의 침수 위험을 감소시키기 위한 효율적인 펌프 운영 기법의 개발이 가능하다. 본 연구에서는 SWMM 5.0 DLL과 Excel을 포함한 Visual Basic 6.0을 연계하여 실시간 운영 모형을 개발하였다. 또한, 효율적인 펌프 운영을 위한 두 개의 펌프 운영 기법을 제안하였다. 첫째는 각 맨홀의 수위를 통하여 현재 상황을 고려한 펌프의 운영이며, 둘째는 실시간으로 운영되는 각 시간단위별 유입량 전량을 배제하는 기법이다. 제안된 두 개의 기법은 현재의 펌프장 운영 기법인 유수지 수위에 따른 펌프 운영을 모의한 결과와 비교하였으며 개발된 모형은 중곡배수분구에 적용되었다.
