چکیده مقاله
Scouring is a natural phenomenon caused by erosive action of flowing water on the bed The formation of a scour hole around bridge piers has been the subject of intensive research for many years Researchers have been introduced a lot of techniques to prevent and reduce local scour at bridge piers In present study, a new method to reduce scouring around piers has been assessed A bubble screen located around the pier are used to counteract the downward flow and avoid the initiation of scour In addition the capability of bubble screens in front half of the pier has been assessed and compared with a complete bubble screen around the pier Results indicate that the complete bubble screen is more efficient than the bubble screens in front half of the pier
