Scale effects arise due to force ratios which are not identical between a model and its full-scale prototype and result in deviations between the scaled model and prototype observations. This paper describes scales effects in vertical slot fishway flow by comparisons of turbulence behaviours measured in 1:4 scale laboratory model and full-scale fishway. Full-scale measurements are exposed. Flow topology, mean flow and unsteady velocity components features, turbulence kinetic energy profiles are evaluated and compared to measurements model.
