The local scour depth is a key parameter in the design of levee engineering. Based on experiment data, a nondimensional analysis for the prediction of local scour depth is related to the approach flow velocity, flow depth, flow angle, scope of levee and the particle size of the bed sediment. The results of this study indicate that the local scour depth increases with the depth averaged velocity and junction angle. Finally, an empirical formula of predicting the gravel channel maximum scouring depth was developed and tested with the experimental data. © 2012 Published by Elsevier Ltd.
