Abstract: A design aiming to a river restoration may require the presence of weirs for reducing both bed slope and solid transport. Gabion stepped weirs have been largely used for this purpose because they are resistant, flexible and environmental friendly structures, but with regard of the hydraulics of these structures, few experimental data and consequently no universally design rules exist. A laboratory model of a gabion stepped chute, discharging up to 0.42 m~2/s, have been realized and tested in order to define the flow type properties. The flow characteristics and the dissipation rate of the gabion stepped structure are analyzed and commented.
