Abstract
Allocated water storage of dam at the planning and design stage does not seem to be maintained well at the operation stage because of unexpected critical reasons. A dam is likely to be subject to negative effects caused by changes of dam operation conditions and it is hardly avoidable. Therefore, it must be timely improved to recover its original functions and looked for better alternatives to keep its original roles. Specifically the improper management of river condition degrades flood control capability in a dam and river eco-system. The dam downstream river improvement work is needed for normalizing dam functions and its valuations. This study focuses on estimating water use benefits from recovering its own effective storage buffer restricted for flood control. As the results, the water supply and the hydropower benefits in Imha, Daechung and Youngdam Dam are recovered totally by 19.9 million $m^3$/year and 20.8 GWh/year respectively. Also those results are used for the basic information of the economic analysis in the dam downstream river improvement work.
