Ecological instream flow were calculated quantitatively based on investigation of the river characteristics and fish habitat in downstream of Yongdam Dam in this study. The river bed and width were not esarlt changed form 1988 to 2004 before and after the dam construction, but the bed materials were finer in 2004 as results of analyzing rrver characteristics. Total 4 families and 11 species of fish including Acheilognathus koreensis were caught and the Coreoleuciscus splendidus using PHABSIM (Physical Habitat Simulation System) considering the river characteristics. The optimal ecological flow for Zacco koreanus was 12.60~13.90 m3/sec and the flow for Coreoleuciscus splendidus was 11.60~15.50 m3/sec in Gamdong and Daeti area. In Bunam area, the flow for Zacco koreanus and Coreoleuciscus splendidus was 7.00 m3/sec. The ecological flow in downstream of the dam was between normal flow rate and high flow rate. |
