In this study, the scour depth and dimensions of the scour depth around different shaped piers were compare. Maximum and Minimum scour depth were find out. The experiments were carried out by using sharp nose, elliptical, Oblong rectangular piers to compare the various scour hole geometries at the same flow conditions. Numerous experiments were conducted in a rectangular flume (25.0 m long, 0.95 m wide and 1.00 m deep) with bridge pier having length and breadth ratio were 2 and 4. The flume bed of 20 cm thickness consists of non uniform graded material with d50=0.65 mm. The experiments were carried out in clear water conditions. The equilibrium scour depths at lateral sides and downstream of the piers were also measured. The shape factor values were also investigated based on the experimental findings and the obtained values were compared to those available in literature. The performance of the obtained empirical relation for circular pier was tested by using limited experimental data available in the literature. The smallest scour hole was observed for the rectangular with sharp noses pier. The increase in the scour hole dimensions for other crosssections was in the following order: sharp nose, elliptical, Oblong rectangular piers.
