  • This study investigates small-scale hydropower generation utilizing the dam water currently released solely for maintaining the river discharge. Toward improving such small-scale hydropower generation, a method for flexible operation of dams is proposed. In flexible operation, a portion of the flood control capacity is allocated to water storage. When a flood is forecasted, it is necessary to release that amount of water to recover the dam's flood control capacity. In conducting such release, accurate forecasting with sufficient lead time is desirable. This study examined the possibility of determining the necessity of water release ahead of forecasted rainfall by estimating the amount of water flowing into the dam reservoir based on forecasted cumulative rainfall computed from numerical weather prediction models (RSM and GSM).The examinations clarified that by employing the proposed method it would be possible to secure water which is about 8 times that currently used for power generation.
