Description :
The AA. examine the effects of roughness elements on the spatial variability of the mean flow velocity profiles and of the properties of turbulent flow structures at the reach scale. The experiment was carried out in 2 reaches of 25 m long in the Eaton North River (Québec). At the reach scale, the distribution of individual roughness elements does not greatly control the spatial variability of turbulent flow properties.
