Abstract

The optimal water allocation pursues a reliable and economic supply of water resources to meet various interests in socio-economic- environmental aspects. The global water shortage has intensified due to climate change and population growth with limited water resources. Thus, the water management scheme has shifted to improve water use efficiency by proper demand management and water allocation planning. Here, a hydro-economic water allocation model, called WAMM (Water Allocation and Management Model) is introduced. The WAMM is equipped with an improved linear programming algorithm for optimal water allocation and estimates economic value of water supply as an objective of water allocation decision. The model is expected to be used as an engineering decision support tool for optimal water allocation and management.

최적화된 물 공급 계획은 물을 둘러싼 이해관계와 사회-경제-환경적 요구사항을 충족시킬 수 있는 합리적이고 경제적인 수자원의 배분 및 활용 방안을 의미한다. 하지만, 전 세계적으로 기후변화와 인구증가 등의 다양한 요인에 의해 물 부족 현상이 심화되고 있다. 최근의 수자원 공급 계획은 수원의 다변화와 더불어 수요 관리 및 물이용 효율을 높이는 방향으로 변화하고 있다. 따라서 한정된 수자원의 이용 효율을 높이고, 물 부족에 따른 분쟁을 해소하기 위한 공학적 도구로써 다양한 물 배분 모형이 개발되어 활용되고 있다. 본 연구에서는 수자원의 용도에 따른 경제적 가치와 물공급 안정성을 기반으로 물 배분 계획을 수립하는 수자원-경제 통합 물 배분 모형을 개발하였다. 개발 모형은 기존 물 배분 모형의 최적화 알고리즘을 개선하고, 목적함수를 다양화함으로써 효율적인 물 배분을 위한 의사결정도구로 활용될 수 있을 것으로 기대한다.
