Appropriate amount of water supply to paddy fields in proper time is important to achieve efficient agricultural water management.
The purpose of this study is to evaluate the irrigation water supply adequacy for paddy fields using water level data in irrigationcanals. For the evaluation, the real-time water level data were collected from main canals in the Dongjin irrigation district for 2years. Using the water level data, delivered irrigation water amounts at the distribution points of each canal were calculated. Thewater balance model for paddy field was designed considering intermittent irrigation and the irrigation water requirement wasestimated. Irrigation water supply adequacy was analyzed from main canals to the irrigation blocks based on the comparison betweenestimated requirement and delivered irrigation water amounts. From the adequacy analysis, irrigation water supply showed poormanagement condition in 2012 with low efficiency except the Daepyong canal section, and the adequacy in 2013 was good or fairexcept the Yongsung canal section. When irrigation water for paddy fields was insufficient, water supply adequacy was affected byirrigation area, but when irrigation water was enough to supply, adequacy was affected by distance from main canal to distributionpoints. These results of the spatial and temporal dimensions of the irrigation adequacy could be utilized for efficient irrigation watermanagement to improve the temporal uniformity and equity in the water distribution for paddy fields.
