A FUNDAMENTAL STUDY ON CLIMATE CHANGE IMPACT ON SEASONAL RESERVOIR OPERATION IN HEAVY SNOWFALL AREA USING 150-YEAR CONTINUOUS CLIMATE EXPERIMENT

Abstract

 This paper investigated the potential impacts of climate change on seasonal operation of the Tedorigawa Reservoir in the Tedori River basin, a heavy snowfall basin in Japan, through the simulation of long-term reservoir operation using a single run of 150-year continuous climate experiment projected by MRI-AGCM3.2S of Meteorological Research Institute, Japan, based on RCP8.5 and SST ensemble mean condition. As a result of investigation, it was shown as a possible future trajectory under climate change that non-negligible changes could be seen in seasonal operation of the reservoir in the late 21^st century, due to changes in snow processes as well as those in streamflow after summer season.
