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 Researchershave been introduced a lot of techniques to prevent and reduce local scour at bridge piers In this paper reduction of scour around circular piers using cable have been carried out and compared with single pier for the case of clear water flow over uniform sediment The efficiency of cables, with different diameters and thread angles are studied through the experiments The result indicated that cable act as a roughness and transits the laminar flow to turbulent flow and pushes separating point to ward downstream and reduces the strength of wake vortex In addition cable reduces the strength of down flow and horseshoes vortex, therefore cable is shown to be effective in reducing scour depth The results showed that with increasing cable diameter and decreasing thread angles the reduction of scour depth increases
