Impact of climate change on operation of reservoir systems for water supply and hydropower in the Tedori River basin, Japan, was investigated to understand possible climate change impacts on water resources management in heavy snowfall areas. Through the simulations of reservoir operation using the 150-year continuous climate experiment projected by MRI-AGCM3.2S of Meteorological Research Institute, Japan, based on RCP8.5 scenario and SST ensemble mean condition of CMIP5 models, it was shown that deficit of water supply significantly increased from summer to fall in the late 21st century, corresponding to relatively great change in seasonal pattern of reservoir storage. The results also showed that power generation by run-of-river power stations may be more affected by climate change than storage stations.
