Study on maximum scour depth of slanting stream in gravel channel

The local scour depth is a key parameter in the design of levee engineering. Based on experiment data, a non-dimensional analysis for the prediction of local scour depth of slanting stream is presented. The maximum scour depth is related to the approach flow velocity, flow depth, flow angle, slope of levee and the particle size of the bed sediment. The test experience formula for estimation of the local maximum depth in gravel channel is also given, it can be employed for engineers in the determination of the levee engineering design.
