Abstarct: Scouring is one of the important issues in the stability of bridge abutments. Large and deep foundations are employed in order to resist the instability due to potential scour. Other less expensive engineering measures are sought in order to reduce the cost while a higher degree of confidence in the stability of the bridge is achieved. The abutment constructed in flood plain are exposed to the river current a couple of times in the period of their designed life time. Spur dykes are examined in this research as a corrective measure for reducing the dimensions of scour hole and more specifically the depth of scour. Variety of discharges was applied to the abutment which was installed in a flume with moveable bed and composite cross section. A spur dyke was placed upstream of the bridge to form the incoming flow in the way it causes the minimum scour around the bridge abutment. The variation in length and the distance from the main structure was investigated for the best result in each discharge. A total number of 158 tests were run and appropriate graphs were plotted. The dykes proved to be a successful measure since they could reduce the scour depth down to zero although the dyke itself faced scouring process around its toe. Since the abutment located in flood plain where the flood is not always present, the damage to the dyke can be easily and inexpensively repaired.
