ダムによる流量変化の特性分析

抄録

We analyzed characteristics of the change of amount of flow caused by dam operation in four views, decrease of disturbance, stabilized flow, trembling change, seasonal change. For the analysis, we proposed the index to represent the four characters based on the data of inflow and outflow and calculated the index of all dams managed by Ministry of Land, Infrastructure and Transport, and Incorporate Administrative Agency Japan Water Agency. Utilizing the index, we tried to represent the characters of every dam objectively and analyzed the reason why the dam has the characters based on the data of capacity for every purpose, facilities to discharge, and the rules for flood control.
