CLIMATE CHANGE IMPACT ON WATER SUPPLY FROM ANOU DAM USING LONG-TERM COUNTINUOUS CLIMATE EXPERIMENT

Abstract

 In order to clarify the impact of climate change on water supply from Anou dam, we used data from long-term continuous experiments under the RCP8.5 scenario of the MRI-AGCM3.2S of the Meteorological Research Institute of the Japan Meteorological Agency. Then, a water supply model simulation was performed using a runoff analysis model. As a result, it was found that in the future the number of days that water supply will be restricted will increase approximately 1.2 to 1.8 times compared to the present climate condition, and the number of days that water supply will be cut off will also increase approximately 1.5 to 2.0 times than the present climate conditions.
