Abstract: Scouring endangers the stability of the hydraulic structures. Studies have considered varied parameters affecting scour around an obstacle. But no substantial work has been done on the impact of obstacle material type on local scouring. The present study analysed the impact of material type of the bridge pier and related parameters on local scour. Cylindrical pier shape was used to simulate the field conditions in the laboratory. Obstacles were made of brick, concrete, wood and steel. Results show noticeable effect of obstacle material on local scour. It was observed that the scour depth and surface roughness of obstacles were inversely correlated and similar was the relation of scour with water absorption. An empirical model was developed to ascertain the maximum scour depth incorporating obstacle parameters. The study will help in better accuracy of scour depth estimation and help in reducing local scour at certain critical junctions of the flow path.
