The Estimation of Daily Evapotranspiration in a watershed by the modified Beken's formula

변형 Beken식에 의한 일별 유역 증발산량 추정

It is important to calculate runoff, percolation and evapotranspiration in process hydrological cycle. Especially, a evaportranspiration in watershed has a very important effect on hydrological cycle. In the study, the watershed evapotranspiration was calculated by the water balance and a daily evaportanspiration coefficient(CE) was calculated by the modified Beken's formula.
