Sediment-flow interactions and effects on bed forms mechanism

Risultato della ricerca: Other


Recent experimental works conducted in mobile bed rectilinear flume seem to verify the existence of a correspondence between the spatial periodicity of horizontal turbulent structures evolving in streamwise direction and the wavelength of bed forms (alternate bars) observed on the bed. In this study, the effect of the variation of the bed roughness conditions on the evolution of such horizontal turbulent structures is analyzed. Peculiar results obtained by using flow velocity data collected along the flume both with flat bed and with deformed bed are reported.
