Application of Submerged Vanes to Control Scouring Around Rectangular Bridge Piers

Authors

Abstract

The present study examines the use of submerged vanes for reducing local scour at rectangular piers with circular nose. Experiments were carried out with piers aligned and skewed at and to the flow, and with submerged vanes at different arrangements. It was found that effectiveness of submerged vanes reduces by increasing the skewness of the pier. Maximum reduction of scouring was 45.57, 39.76 and 27.78% for submerged vanes with height 2.5cm on the bed and skewed at to the flow when was aligned, skewed at and skewed at to the flow, respectively.
