수자원의 정량화, 확보 및 효율적인 관리가 시급한 이유는 무엇인가? | 기후변화로 인한 수자원 변동성이 증가함에 대표적인 극심한 물 부족 국가인 우리나라는 장기적인 가뭄으로 전국적인 물 부족현상이 가중이 되고 있어 수자원의 정량화, 확보 및 효율적인 관리가 시급한 실정이다(Kwon et al., 2009). | |
인간이 활용할 수 있는 물의 최대량이란 무엇인가? | 일반적으로 강수량을 통해서 인간이 활용할 수 있는 물의 최대량은 증발산량(강수량의 2/3)을 제외한 나머지 값이다. 이렇게 중요한 증발산량을 정량화함으로써 수자원에 필요로 하는 사용가능한 양을 파악할 수 있지만, 대기와 지표 사이의 여러 요인(토양수분, 식생, 기상 등)의 영향을 받기 때문에, 시간적으로나 공간적으로 정량화하기에 어렵다(Kim et al. | |
증발산량을 지금까지 어떻게 파악하고 있는가? | , 2018). 지금까지 단순 가정식 또는 경험식을 이용한 증발산 산정 방법 및 현장 실측 기기(lysimeter, flux tower)들을 사용함으로써 증발산에 대한 정량화 및 변동성을 파악하고 있다(Hong et al., 2008; Kwon et al. |
