Analysis of Irrigation Effect in the Paddy Plot Irrigated by Pipelines With an Automatic Hydrant

관수로 자동급수전의 관개효과 분석 -충북 보은군 학림 관수로 지구를 대상으로-

In this study, we investigated irrigation effect for the paddy plot irrigated by pipeline with two types of hydrants: automatic and manual. The automatic hydrant have been introduced to the paddy field to save water and reduce the labor for water management. The automatic hydrant is automatically opened and closed according to the water depth of a paddy plot. The water management labor to close manual hydrant in the afternoon of every three days can be eliminated when we use the automatic hydrant. The water requirements for the automatic hydrant plot 3.26mm/d are much less than those for manual hydrant plot 9.99mm/d.
