Abstract
This study presents effects of downstream control point by coupled operation of dams and multi function weirs in the Geum River. Geum river basin that study area did authoritativeness high quality data to acquisition possibility. We applied the flow duration curve, flow regime coefficient, impounded flow index analysis to investigate the quantitative changes in natural flow regimes. In sphere that water supply is possible, this study applied believability that satisfy 95% at estimation year. Impounded flow index was calculated 0.292 by dam coupled operation and 0.297 by dam-weir coupled operation. The results indicate that the storage amount is increased by 29.7% as being added. Duration flow of downstream control point was improved because became coupled operation by regulation of dam and weir in the geum river.
