[ 1 ] - Effect of Collars and Bars in Reducing the Local Scour Around Cylindrical Bridge Piers

In the present work, the efficiency of single and double collar in reducing scour rate and depth around cylindrical bridge piers was studied experimentally. In order to reduce the strength of wake vortices, different numbers of bars were also installed at the downstream face of the pier in combination with a single collar. The best result was achieved for double collar when the collars were ins...
