Estimation of water efficiency for the irrigation pumping area in the Han River basin

A term, $\ulcorner$Water Efficiency$\lrcorner$ was defined as a measure for the effective water management improvements in agriculture. To estimate the water efficiency, 7-year (1993∼1999) historical pumping records were collected from 59 pumping stations and water requirements of paddy fields for each station were estimated in the Han River basin. The water efficiency was estimated monthly and annually, and the assessment of the results was performed for each station and the associated branch offices of KARICO.
