Energy dissipation over large-scale roughness for both transition and uniform flow conditions

Rock chutes are natural river training structures and are efficient energy dissipaters too. from the hydraulic andenvironmental point of view, rock chutes have become important structures in the natural river morphology. a physical studywas conducted and flow properties were measured over rough bed materials of a rock chute, which was assembled at thepitlab center of the university of pisa, italy. experiments were performed for slopes varying between 0.18≤ s ≤0.38, 0.03
