This study presented a method for estimating the environmental flow in a stream using the physical habitat simulation. The study site is a reach of the Naeseong-cheon Stream downstream from the Youngju Dam in Korea. The study reach is 20 km long, extending from the Mirim-gyo Bridge to Miho-cheon Station. The physical habitat simulation was carried out for Zaceo platypus, the target fish. A ID flow model and habitat suitability curves were used for hydraulic and habitat simulations, respectively. Using the simulated results, the weighted usable area versus discharge was given, and the environmental flow was estimated. In the present study, the environmental flow was defined by the discharge that produces 80% of the maximum weighted usable area. The environmental flow was presented and compared with those from the hydrological and hydraulic rating methods. It was found that the environmental flow from the physical habitat simulation is the largest, followed by those by the hydraulic rating method and the hydrological method.
