Impact assessment of climate change on water resources in the Kiso River basin using NHRCM5km data
抄録
This study evaluated the changes in river discharge due to climate change using an integrated water resource model. This model, a combination of Simple Biosphere Model(SiBUC), Rainfall-Runoff-Inundation Model (RRI) and Reservoir Operation Model (ROM), considers the impact of reservoirs on the hydrological cycle and allows description of water and energy at the basin scale. The results annual River discharge trends to decrease. But there are no obvious changes in winter though precipitation trends to decrease. The probable reason is an increase of snow melting. In the heavy rainfall season from June to September, the average monthly discharge will decrease from present to future excluding July. There is an obvious decrease in August from present to future. Peak flow in September seems to move forward from late of the month to early of the month. Extreme flow (daily maximum) tends to increase during the projected period. Generally, the decrease in total discharge and increase in extreme discharge will bring large challenges to future water resource management.
