| Ecological instream flow was quantitatively calculated based on the river characteristics and fish habitat in the downstream of Yongdam Reservoir. The river bed and width did not change from 1988 before the am construction to 2004 after the dam construction, but the bed sediment size was attenuated a little in 2004. According to result that investigate fishes, 4 family 11 species including Acheilognathus koreensis were collected. Among them, Zacceo koreanus of cyprinidae was dominant, and Coreoleuciscus splendidus did sub-dominant. The habitat suitability indexes were estimated for two fish species Zacco koreanus and Coreoleuciscus splendidus using Physical Habitat Simulation System (PHABSIM) considering the river characteristics. In Gamdong and Daeti sites, the optimal ecological flow for Z. koreanus and C. splendidus were $13.90sim12.60;m^3;s^{-1}$ and $15.50sim11.60;m^3;s^{-1}$, respectively. In contrast, the optimal flow for the two species in Bunam site were $7.00;m^3;s^{-1}$. The ecological instream flow in the downstream of Yongdam Reservoir was between normal and high flow rate. |
