| Outline of Final Research Achievements |
Developing countries in Southeast Asia experience frequent floods and droughts, and advanced watershed managements from both flood control and water utilization perspectives are urgently required. This study aimed to develop an optimization method for reservoir operation rules through integrated management of multi-purpose reservoirs to effectively solve water problems, and to propose a protocol for integrated management of reservoirs to avoid water risks under climate change. We developed a distributed rainfall-runoff model incorporating multiple reservoirs to enable runoff calculations that expresses changes in runoff during dry and rainy seasons and reservoir operations. We also proposed a method for evaluating the impact of changes in water resources and water use period on the water supply-demand balance under climate change, and established a foundation for developing an integrated management protocol for multiple reservoirs, especially for avoiding drought risks.

治水と利水はトレードオフな関係にあることから，両面に対する問題をバランス良く効率的に解決する流域水管理手法の構築が求められていた．また，東南アジア流域では，流域水管理モデルの構築に必須となる各種データが低精度あるいは入手不可能なことが多く，データ寡少な中でもいかに定量的にモデリングするか，適用可能な手法を構築するかも重要な課題であった．本研究は，近年の気候変動が水資源や水利用に及ぼす影響も考慮しつつ，これらの課題解決を目指して実施されたものである．
