Evaluation of Dam Water-Supply Capacity in Korea Using the Water-Shortage Index

This study evaluates the dam water-supply capacity in Korea using water shortage index. The water-shortage index (SI) and generalized (GSI) used this are evaluated modified slightly by considering both damage cost due to failure construction of systems Korea. indices then applied for performance evaluation 16 multipurpose dams Korea, whose results different units: each dam, river basin, all dams. In analysis level basin level, problems detected several some basins. However, SI GSI estimated found be lower than 1. result indicates that, even though total amount storage is enough satisfy design supply, resources not well spatially distributed It also that valid describe deficient regions during occurrence years major droughts. conclusion, can offer alternative ways evaluating supply under environmental conditions potentially help determine optimal water-storage
