  • This paper investigates how to operate existing dams as an adaptation to climate change. In cold, snowy regions, climate change is causing temperatures to rise and snowfall to decrease. This is expected to shift the snow-melting season earlier, to decrease river discharge and, consequently, to influence water. We estimated future changes in hydrologic processes and average annual water levels for dams in the Toyohira River catchment area. Using reproductions (1981-2000) and future estimates (2081-2100) provided by the Regional Climate Model of the Japan Meteorological Agency (RCM20), we estimated the future hydrological cycle of the Toyohira River basin in order to estimate changes in water levels of statistically normal dams. The simulation shows that a reduction of snowmelt runoff will cause dam discharge to decrease, which may result in water supply shortages. However it also suggests that coordinating the discharge operations of two dams can effectively address those water shortages.
