Investigation on scoring and determination of depth of scoring are among the most important issues in square pier designation with model ogival pier was measured in a laboratory flume with 180° bend with a relative curvature of bend of 4.67 under clear‐water. One ogival model pier was used for the study in different Froude numbers and positions were tested. Natural sand with uniform graining of d50 = 1.3 mm and uniformity factor of 1.4 were used as bed materials. The results of the model study indicated that the maximum depth of scour is highly dependent on the experimental duration. The results of this study show that, while ogival pier is placed in the bend, the maximum scouring depth is occurs in position of 60°. Also it was observed that in all positions, the scouring depth increases as the Froude number increasing.
