Abstract: This study investigates the effect of bed load transport on the equivalent roughness of a flow. To do so, a series of aggradation experiments with supercritical flow are performed in a laboratory channel and corresponding numerical simulations are run. Matching the experimental and numerical profiles, calibrated values are obtained for the Manning coefficient and a bed load factor. The calibrated Manning coefficient is larger than that estimated in preliminary experiments without sediment transport. Engineering, 147 (10): 4021034
