Abstract

In recent, the integrated water resources management should consider not only existing management objects such as water supply, power generation, and instream flows but also new management objects such as water quantity, water quality, and water habitats which management system is large and complex. Moreover, integrated basin plan or operation are needed for solving conflicts problems between basins and between water usages and to maximize water resources usages. To increase use of optimization method for actual operation and apply various objects, a reservoir operation rule was developed and the KModSim's hydrologic states for integrated water resources management were tested in this study. The simulation results show that the developed operation rules applied in hydrologic states good represent the actual storages of both the Yongdam and the Daecheong Reservoirs so, it is possible to improve the water allocation method usually used in the basin management and manage the integrated basin water resources if new operating rules are applied in optimized programming.

최근의 유역통합관리는 용수공급, 수력발전, 그리고 유지용수 등과 같은 기존의 운영방안과 더불어 수량, 수질, 생태계 보호를 함께 고려해야만 하는 등 운영목적이 복잡해지고 시스템 또한 대규모화 되고 있다. 더불어 용수이용 혹은 유역간 서로 상충되는 이해관계가 발생함에 따라 물이용의 효율성을 극대화할 수 있는 범 유역 단위의 수자원 계획 및 운영이 필요하게 되었다. 최적화 모형의 현실 활용 기회를 높이고, 수자원관리의 다양한 운영목적을 수자원 운영에 반영하기 위하여 본 연구에서는 저수지 운영률을 개발하고 이를 적용하기 위한 KModSim의 수문학적상태방법에 대한 적용성을 검토하였다. 본 연구에서 개발된 운영률은 전체적으로 용담댐과 대청댐의 실적저류량을 잘 재현하는 것으로 나타났으며, 이를 최적화 모형에 활용한다면 관행적으로 적용해온 물수지 분석 방법을 개선할 뿐만 아니라 유역통합수자원관리가 가능할 것으로 기대된다.
