Abstract

In this study, we used MRI-AGCM 3.2 S resolution of 20 km, which is a climate model provided by Program for Risk Information on Climate Change, to input to the land surface model SiBUC, and for multiple future scenarios, assessed the uncertainty of changes in land hydrological quantities due to climate change. We used SiBUC to calculate vertical water balance and used Hydro-BEAM to track spatial and temporal fluctuations. In the future, precipitation and rainfall were uncertainty around Aichi Prefecture and western Japan. At the future flow, in winter, the value changes dramatically, but the difference between models was small, so uncertainty was small. On the other hand, in summer, there were variations between models in any river and uncertainty was large.
