Outline of Final Research Achievements

Focused on extremes (droughts and floods), which are expected to increase in future, a Seamless DIF (Distributed Water Circulation, Inundation and Flood) model to consecutively simulate agricultural water use and floods was developed. In relation to long-term analyses of agricultural water use, events of floods and droughts have been analyzed independently as separate short-term phenomena, although these now cause severe disasters in many places. Yet, the necessity for their replication over their expanded areas and for the integrated basin-scale management of agricultural lands and water use facilities requires us to handle water use and floods continuously. By establishing a model to seamlessly track both, we extended our outcome application to adaptive watershed management against devastating calamities that initiatively utilizes flood prevention functions of paddies and to propose “basin-scale irrigation planning” in the areas applied despite the scarcity of data.
