초록

상수관망의 수리해석 방법은 demand-driven analysis와 pressure-driven analysis로 구분할 수 있으며, 급작스런 용수수요증가, 관거파괴 등과 같이 비정상운영상태인 용수공급시스템의 수리모의에 demand-driven analysis를 사용할 경우 비현실적인 결과를 줄 수 있다. 특히 현재 국내에서는 비상상황에 대한 비상급수계획 수립 시에 demand-driven analysis를 사용하고 있으나, pressure-driven analysis의 적용을 통한 비상급수계획의 적정성 평가가 수행되어야 할 것이다. 본 연구에서는 pressure-driven analysis를 위해 최근 개발된 WaterGEMS모형을 이용하여 2007년 수도정비 사업을 계획한 J시의 비상급수계획의 적정성을 평가하였다. 적용 결과 소블럭의 용수공급 안정성 향상을 위한 방안 제시가 가능하였으며, 수립된 비상급수계획이 적합한 것으로 판단되었다.

Hydraulic analysis of water distribution system can be divided into demand-driven analysis and pressure-driven analysis. Demanddriven analysis can give unrealistic results to simulate hydraulic conditions under abnormal operating conditions such as sudden demand increase and pipe failure. In Korea, demand-driven analysis has been used to establish emergency water supply plan in many water projects, but it is necessary to use pressure-driven analysis for establishment of emergency water supply plan. In this study, WaterGEMS model that was developed for pressure-driven analysis is used to evaluation of emergency water supply plan of J city. As the results, it was able to draw up more efficient plan for water supply in small block, and established emergency water supply plan of J city was determined to be appropriate.
