SWAT 모형이란 무엇인가? | SWAT 모형은 미국 농무성 농업연구소(USDA Agricultural Research Service, ARS) 에서 개발된 일 단위 모의가 가능한 유역단위의 준분포형 모형이다(Arnold et al., 1996). | |
SWAT 모형은 어떤 지표들에 대해 각 수문반응단위(HRU) 별로 계산이 가능한가? | , 1996). 물리적 기반의 준분포형 장기 강우-유출 모형으로서, 대규모의 복잡한 유역에서 장기간에 걸친 다양한 토양과 토지이용 및 토지관리 상태에 따른 유출의 영향을 예측하기 위해 개발되었으며 물수지 방정식에 근거를 두고 강수, 증발산, 지표유출, 기저유출, 지하수, 토양수분 등에 대한 모의를 각 수문반응단위(HRU) 별로 계산 할 수 있다(Arnold et al., 1998). | |
SWAT 모형에서 일별 유출량과 잠재증발산량은 각각 어떤 방법을 통해 산정하는가? | , 1998). SWAT 모형에서 일별 유출량은 SCS(Soil Conservation Service) CN (Curve Number) 방법을 통하여 산정하며, 잠재증발산량은 Penman-Monteith 방법을 이용한다. SWAT 모형에서 사용되는 물수지 방정식은 다음과 같다(Neitsch et al. |
