Vertical-slot fishway is widely used in different shape of fish-way due to the adaptability to water level amplitude, the hydraulic characteristics of the vertical-slot fish-way of different scale has been extensively researched by researcher domestic and overseas, the energy dissipation mechanism and hydraulic characteristics of the fish-way in different scale under different inflow has been acquainted now. In this paper, the hydraulic characteristics of Vertical-slot fish-way of different size under water depth, inflow and slope is analyzed, influence of water depth, flow velocity, dissipation rating per unit volume and turbulent energy etc. On fish swimming ability is discussed, and design of fish-way is evaluated by relevant hydraulic factor of fish swimming characteristics. Finally the research method and experience abroad is summarized in the paper.
