気候変化の適応策としてのダムの治水・利水容量の再配分に関する考察-紀の川流域を例として

Using existing stock is important to plan the adaptation policy under climate change. This study is focus on evaluation about multi purpose dam volume reallocation from water use to flood control and "trade-off"problem. In kino river basin, we input bias corrected and temporal/special downscaling 10 GCM output data to hydrological model which can represent long-term water circulation and simulate dam storage. The simulation indicates that drought risk shift is not common trend in each GCM without dam, but it will decrease mutually with dam which can storage increased flood. In addition, reallocation method enable to avoid exceedance flood or to make evaluate delay time and ease peak flow.
