Abstract: A pilot study has been carried out at the vertical slot fish passage of Cataloluk Small Hydropower Plant (SHP), which is located in Ceyhan River Basin in Tekir River in Turkey. Accordingly, 3D velocities and turbulence quantities were collected at several points in the pool with Acoustic Doppler Velocimeter (ADV) for various discharges at the Cataloluk fish passage. The pool depth was measured continuously through the year by using Ultrasonic Distance Sensor (UDS). The UDS monitoring data revealed that pool depth is highly variable during operation that can have important implications for fish passage design. The fish movements were recorded continuously in the selected pool with underwater digital video cameras. The prototype measurements showed that by placing brush blocks in the vertical slot pool, the flow energy is effectively dissipated by the vibrations and bending of the bristles leading to an about 17% reduction in the spatially averaged turbulence kinetic energy. The proposed monitoring technique is cost-effective, efficient, and easy to implement in existing pooltype fish passages.
