Hydroelectric power is sustainable and a pure domestic energy with low CO2 emissions. It is necessary to promote a further enhancement in the future. While it has been difficult to construct a new dam due to the environmental impacts and fiscal tightening, retarding basins have been recognized as leading plans for flood control in recent years. Because basically there is no submerged houses in basins and they are environmentally friendly. In this study, we recognize retarding basins are utilized not only for flood control but for water resources; enhancing effect of hydroelectric power is one of efficient and significant ways of their roles. This paper identifies the potential for the power development to examine increased power of the downstream power plant with assumptions of discharging water in accordance with the conditions. Experimental results from the Shinano River are being used as numerical model simulations to provide insights here.
