Abstract

The main aim of this study is to find a practical shape of bridge pier being a local scour countermeasure. Therefore, the semi-conical piers have been selected to make their usage applicable in the field. These piers have small side slope angles and rectangular cross-section. Also, the secondary aim is to increase the efficiency of the above countermeasure. So, the first experimental set has been performed using a vertical cylindrical pier (its side slope angle = 0) and three semi-conical piers with different side slope angles (2.860, 5.70 & 8.50). The results show that increasing the side slope angle leads to increase the Reduction Percentage of Scour Depth and Volume (RPSDV). The values of RPSDV are (18.33, 21.66, 25) & (40.2, 54.9, 60), respectively. Also, the second set has been done and consists of the three semi-conical piers that their leading edge are integrated or modified with devices. These devices are: openings, up-stream ladder, and curved face. The values of RPSDV are improved using these devices compared with the semi-conical pier without device. The RPSDV are (3.3, 26.7, 37.8) & (1, 53, 68), respectively.
