Effect of Fenders on Local Pier Scour

Document Type: Proceeding Paper

Part of: Hydraulic Engineering

Abstract:

Physical model experiments were performed in the Hydraulics and Sediment Research Institute, Delta Barrage, Egypt, to determine the effect of fenders on the scour depth around circular bridge piers. The experiments determined the size of the scour hole around a circular pier with and without a floating box shape (open from the bottom ) fender. The fender was placed at different submerged depths. It was found that fenders decrease the depth of local scour around circular piers and the scour depths decreased with an increase of submergence of the fender.
