DEVELOPMENT OF ECO FRIENDLY FISHWAY OF INSTALLATION FOR DAM

摘要

PURPOSE: A fishway facility installed in a dam is provided to prevent fish species from being depleted, since homing fishes freely moves to the upstream and downstream of the dam through a fishway. CONSTITUTION: A fishway facility installed in a dam comprises a fishway water supply unit(130), a reservoir wall(111), a fishway(100), and a hydraulic pressure absorbing unit(112). The fishway water supply unit is installed on the upstream of the dam. The reservoir wall is installed on the downstream of the dam and is formed with grooves. The fishway connects the water supply unit and the reservoir wall and is installed with partitions(114). A hydraulic pressure absorbing unit is installed between the reservoir wall and the fishway.
