| Research Abstract |
Focused on extremes (droughts and floods), which are expected to increase in future, impact assessment of global warming on agricultural water use and drainage are carried out and countermeasures against those were evaluated by utilizing water management of reservoir operation and flood prevention function of paddies. In this approach, this water circulation model turned out to estimate the cropping area of rice paddies, the water requirements of paddy fields, at any location and time in the basin, as well as water availability as runoff amounts. In addition, the change of rainfall amounts in different durations due to global warming were examined, so that a systematic generation method for internal rainfall patterns was developed.
