Performance Evaluation of Scour Protection around a Bridge Pier through Experimental Approach

Bridge pier scour threatens the stability of bridges. Several approaches practiced counterbalancing the base of piers from scour, but the use of a collar with protection is considered as effective countermeasure. Present study examines the scour around rectangular cross-sectional pier by applying a...

Several approaches practiced counterbalancing the base of piers from scour, but the use of a collar with protection is considered as effective countermeasure. Present study examines the scour around rectangular cross-sectional pier by applying a rectangular hooked collar, under clear water condition.
