Abstract: In the present paper, the hydraulic characteristics of the brush-type fish pass have been experimentally investigated. The hydraulic test results reveal that the brush fish pass fulfills the requirements of an efficient fishway by providing tranquil flows and sufficient flow depths for different fish species. Flexible hydraulic elements were referred to with three parameters as Cauchy number, the areal density of brush elements, and channel bed slope. The wall friction plays only a minor role in this process. The Darcy-Weisbach friction factor was derived from dimensional analysis and experimental measurements. By using the proposed formula, crosssectional average velocity and discharge can be estimated for the given channel geometry data. Bed slope appears to be one of the main parameters that control the magnitudes of energy dissipation and turbulent kinetic energy.
