This paper reports the studies carried out on afflux at bridge piers on rigid bed, at Indian Institute of Technology, Kharagpur. Four different shapes of piers, each having the same tail and nose, were chosen for investigation. The experiments were conducted to determine the efficient type of pier. It was observed that the piers with semi-circular and 60° triangular ends showed minimum afflux. It Was also observed that the afflux increases with discharge and decreases with the increase in downstream depth.
