11. A simplified experimental method to evaluate equivalent roughness of vegetated river beds

Author

Abstract

In this paper a new method to experimentally evaluate roughness of vegetated river beds is proposed. Unlike the usual method of attaining uniform flow, the new method is based on measurements performed in boundary layer flows, conditions that in flow experiments with plants can be attained easier then in uniform flows. The described method can be applied either in case of smooth or vegetated walls. The friction factor f and Manning’s n values so obtained are in agreement with literature results.

Abstract

At the present time, the impact of free stream turbulence on fully turbulent boundary layer flow has been examined in numerous experimental, analytical and computational studies. Many of these studies [1]..[12] deal with the effects of the free stream turbulence on the main statistical turbulence quantities (for example mean velocities, turbulent shear stress, turbulent kinetic energy): in particular some workers have studied Length Scales, Skewness and Kurtosis, which will be used in this paper.
