This study aims to propose improvement measures of flood control and water use for existing multi-purpose dams. Functions of dams will be enhanced by temporary change of a capacity from water use to flood control, while that from flood control to water use as well as environmental recovery and small hydro-power. Improvement of functions of the existing facilities gives a promise as an effective measure because unexpected flood and drought due to future climate change are expected as well as new facilities are difficult to be developed.The former means an operation to enhance the flood control capacity by prior releasing from dam reservoir when flood is predicted, while the latter means an operation to keep more water than the normal capacity for water use for utilization to small hydro-power etc. Both are required an accurate prediction of rainfall and inflow to dam reservoir, thus improvement measures of dam functions using such information were proposed.

本研究旨在对既有水利枢纽的防洪用水提出改进措施。从用水到防洪、从防洪到用水以及环境恢复和小水电的临时能力变化，将增强大坝的功能。现有设施的功能改善是一种有效的措施，因为预计未来气候变化导致的意外洪涝和干旱，以及新设施的开发难度。前者是指在预报洪水时提前从大坝水库放水来提高防洪能力的操作，而后者是指将超过正常用水能力的水保持更多用于小水电等的操作。两者都需要准确预测降雨和入库流量，因此提出了利用这些信息改善大坝功能的措施。
