실용적 농업용수산정기법을 이용한 K-WEAP의 적용

Application of K-WEAP using Practical Calculation of Agricultural Water

The agricultural water demand that is calculated in present is difference with practical one by various situations in field. And, by various change, agricultural water demand can not estimate by agricultural land area simply. Considering various situations in field, calculated practical agricultural water demand and applied it to Korea Water Evaluation And Planing System (K-WEAP) in this study. The studied area is Seongju. The studied results showed that agricultural water demand calculate about 5.8 percent higher than existing one, and the agricultural water demand that is applied to K-WEAP calculate about $4{\sim}5.5$ percent higher. Total Agricultural water demand increased about 0.5 percent until 2011.
