Abstract: The hydraulic characteristics in the pool of vertical cross-set slots fishway with deflecting block were researched through 1∶10 partial fishway model test. The hydraulic factors such as flow regime, velocity distribution in the pool and the suitable upstream path for targeted fishes were observed, and the baffle shape, slot width and pool length were analyzed. The results verified the rationality of the baffle type, pool size, and parameters of the fishway. Through live fish experiment, we get the physiological characteristics and hydraulic conditions favorable for the breeding migration of four major Chinese carps.

Key words: fishway, migration, vertical cross-set slots fishway with deflecting block , pool room, flow velocity
