초록

우리나라는 여름철에 강수량이 집중되고 동고서저형의 지형을 가지고 있다. 이러한 지형과 조건을 가진 나라는 기본적으로 하드웨어적인 대책이 뒷받침되어야 한다. 하지만 점차 그 적지는 감소하고 있고 국가 수자원 정책에 대한 시민 및 언론의 반발은 거세지고 있는 상황에 처해있다. 이러한 상황에서 기후변화는 수자원에 많은 영향을 주고 밀접한 관계를 가지고 있다. 따라서 본 논문에서는 기상청 기후변화 시나리오인 RCP 4.5와 8.5 시나리오를 검 보정한 SWAT모형에 적용하여 밀양다목적댐 유역의 미래 유입량을 산정하고 이에 대한 분석 결과를 바탕으로 댐을 운영하는데 있어 미래 방향을 제시하였다. 기존의 봉우리형 강우패턴에서 겨울철에도 비가 오는 평탄한 형상으로 변화할 것으로 예측되었다. 따라서 기존의 운영룰에서 변화하는 강우 패턴에 맞는 방향으로 댐의 운영룰을 수정하고 이에 대처할 수 있는 방안의 마련이 필요할 것으로 판단된다.

The Korea Academia-Industrial cooperation Society. The Korea Academia-Industrial cooperation Society. In Korea, the territory has east high west low type and the rainfall is concentrated in the summer season. A nation having these topography and precipitation condition like Korea has to basically needs support of hardware alternatives. However, the right places decrease gradually and the resistance of the public opinion for national water resources policy stiffens gradually. The climate change has an effect in water resources fields and has a close relation. In the present study, therefore, future inflow of Miryang multipurpose dam basin is estimated by using SWAT model applied RCP 4.5 and 8.5 scenarios of "Korea Meteorological Administration" and considering the results, the future direction is purposed to operate the dam. As a result, the rainfall pattern is changed from traditional peak form to flat form. The dam operation rule in accordance with changing precipitation pattern has to be modified from the conventional operation rule and a new plan has to be established to meet a situation.
