| Research Abstract |
One of the techniques used to prevent heat damage to ripening rice is water management during the summer. There is, however, little knowledge about changes in the temperature of water running through irrigation canals. In this study, the spatial distribution of water temperature in irrigation canals, which are pipelines and/or open canals, was investigated. It was shown that the temperature of downstream irrigation water is about the same as that of water at the upstream source. In contrast, at the observation points in open canals in the study area, there was a wide variation in the day-night differences in water temperature.
