DESIGN METHOD OF TIME-DEPENDENT LOCAL SCOUR AT CIRCULAR BRIDGE PIER

A reliable prediction of local scour depth related to hydrologic characteristics such as peak discharge and time corresponding to the equilibrium scour depth are essential for the efficient design of bridge pier foundation. In this paper, a design method to predict the local scour depth with time is proposed. An experimental program was carried out using a cylindrical pier placed in uniform beds under clear-water flows. The pier scour depth was calculated on the basis of a sediment transport equation. Equilibrium local scour depth is reached when the bed-shear stress tends to critical bed-shear stress in the scour hole. Hence, changes to bed-shear stress at the circular bridge pier should be incorporated in the sediment transport theory. The proposed method follows experimental data of various sources.
