농업용수 공급량과 관련된 연구에는 어떤 것이 있는가? | , 2012)가 수행된 바 있다. Yoo et al. (2013)은 기후변화와 이에 따른 토지이용 및 생육시기 변화를 고려하여 미래 농업용 저수지 수요량을 산정하였다. 여기서, 관개효율은 지역별 특성을 고려하여 저수지별로 80∼90%가 적용되었으며 시간에 따른 변화는 고려되지 않았다. 또한, Song et al. (2013)은 농업용수 공급량 모형과 논 광역 배수량 모형을 연계하여 복합영농 관개지구의 배수량을 모의하였으며, 여기서 송수 효율은 95%, 그리고 배분 효율은 현장의 실측치를 반영하여 73% 가 적용된 바 있다. 이상의 연구들은 농업용수 공급량에 대한 정확한 추정이 기반되어야 하며, 이는 장래 용수수요 추정, 용수수급 계획, 관개조직의 운영 등 수자원 관리계획 수립에 있어 중요한 요소로 작용한다. | |
농업용수 공급량이란? | 농업용수 공급량(agricultural water supply)은 관리자가 수리시설물에서 관개지구로 실제로 공급하는 용수량을 의미하며 농경지에서 작물재배를 위해 이용되는 필요수량 (irrigation water requirement), 수로에서 손실되는 송수 손실 수량(conveyance loss), 그리고 포장으로 유입되지 않고 하천으로 직접 회귀하는 배분관리 용수량(delivery management water requirement)을 포함한다(Song, 2013; Song et al., 2015). | |
농업용수 공급량 조사를 위한 가장 정확한 방법은 무엇인가? | 농업용수 공급량 조사를 위한 가장 정확한 방법은 용수로의 시점부에 장비를 설치하여 연속 측정하는 것이다. 최근에는 농촌수자원 스마트 물관리를 위하여 첨단 센서 네트워크를 이용하여 실시간으로 농업용수 공급량을 측정하는 지역이 있으나(Park et al. |
