Measure and Classification of Agricultural Water Losses

농업용수 물손실 유형에 따른 손실량 재정립

Agricultural water is the main portion of water resources in Korea. And water loss of agricultural water is estimated 6% of all water resources. But studies and data for water loss aren't sufficient. We classified the agricultural water losses and measured the water losses in 6 experimental site. Measurements says that water losses ratio in main canal is 13.8%, water losses for distributing irrigation water is 31.1%. So, the total water losses is about 45%. But the water losses for distributing irrigation water is imperative factor for irrigation, So, it is not right that the water losses for distributing irrigation water is classified water losses and it is necessary to reclassify the agricultural water losses.
