The variation in runoff due to global climate change and urbanization should be identified quantitatively because these two factors have been significantly accelerated during the last three decades in South Korea. However, only a few research to analyze the impacts due to two factors over different ...

유량자료란 무엇인가? | 유량자료는 특정 유역 내에서 발생되는 하천정비사업, 보의 설치, 준설, 도시개발사업 등과 같은 인간의 활동에 의한 변화 및 온도의 증가나 강수의 변화 등과 같은 자연적 요소에 의한 변화를 모두 포함한 결과로 볼 수 있으며, 시·공간적으로 변화된다. 물순환에 영향을 미치는 요인을 분석하기 위한 기존 연구는 수문학적 요인들과 자연적 요인 및 인위적 요인들 사이의 관계를 규명하는 데 초점을 두고 진행되었다(Pike, 1964; Nash and Gleick, 1991; Burn, 1994). | |
변동점 탐색은 어떤 통계량을 주로 이용하는가? | 이와 같은 급진적 변동을 분석하기 위해서는 변동점 탐색이 시행된다. 변동점 탐색은 Pettitt (1979)이 개발한 비모수검정통계량을 이용하는 경우가 많다. Rouge et al. | |
수문학적 민감도 분석의 시행을 위한 기초적인 이론을 제공하는 연구들에는 어떤 것들이 있는가? | 수문학적 민감도 분석 방법을 이용한 유량변동량의 산정 연구는 수문학적 민감도 분석의 시행을 위한 기초적인 이론을 제공하는 연구들이다. Koster and Suarez (1999)는 토양수분의 흐름을 단순구조로 파악하고 기초적인 변화를 탐색하는 연구를 수행하였다. Zhang et al. (2001)은 유역 단위에서 식생의 변화에 따른 연평균 증발산의 반응에 연구하였고, 연구결 과를 바탕으로 식생계수를 제안하였다. Arora (2002)는 건조 지수(aridity index)를 이용해 기후변화로 인해 영향을 받는 연유량을 평가한 바 있다. |
