Abstract: In this study, examines Gapcheon, located in Korea, divided the habitats of organisms living in the river as a habitant ground into 10 types, Then, using a two dimensional hydraulic model RIVER2D, the potential value of aquatic physical habitat for different flow conditions was evaluated by weighted usable area in "Channel Connected Pool. " Physical habitat evaluation was carried out for one week flow with comparison between the natural flow regime and the artificial variations due to hydro-peaking generation. Through this study, 2-Dimensional model RIVER2D can be adapt to estimate the aquatic physical habitat condition for identified fish in the stream. The channel connected pool has value of more than average as a fish habitat, it is verified by target fish Zacco platypus. For operating this model usefully, it is necessary that HSI to be founded by plentiful field data accumulation of varied fish. Also the variations of water level by seasonal influence and the difference of regional conditions to be considered.
