Evaluation of Sediment Gradation Effects on Clear-Water Pier Scour with Densimetric Froude Number
This study evaluates sediment gradation effects on clear-water scour at bridge piers. By considering the average erosion and deposition rates in a pier-scour hole, the normalized equilibrium scour depth is theoretically shown to be a cubic function of the densimetric Froude number. Comparisons with experimental data demonstrate that the cubic law achieves its best fit when the representative particle size is taken to be . The present prediction equation, which is founded on rational theoretical principles, provides an improved approach to evaluating sediment gradation effects on clear-water scour around bridge piers apart for pure empiricism.
