| Summary | Increasing electric-power production has been expected after the Great East Japan Earthquake. Utilization of unused water-energy on the established dams and power plants is effective in order to increase of electric-power by low costs and CO2 emission. Changing the operation of Multi-purpose dam reservoirs, to raise the water level or to use more deposited water quantity, will make some gain of the water generation power of the dam. We assume 4 patterns of changing the dam operation and calculate the amount of increase the water-power production. Furthermore, we estimate the impacts on the flood control or water resource management facilities and environment in reservoirs, and restrictions by the existing system, laws or regulations related dams, following the change of the reservoir operation. On the other hand, this study also evaluates the potential of the other measures of increasing water-power production, such as the establishment of the new small water-generations for dam management. |
