Abstract :The scouring problem caused by the flow movement in the downstream areas of hydraulic structures is an issue that keeps its actuality. In order to prevent these scouring to occur in the downstream, various typed energy dissipaters are placed on the downstream of the hydraulic structures. Factors such as sediment type, the velocity of the stream, and flow regime play an important role in scouring. In order to prevent scouring, the flow’s energy must be dissipated before meeting the sediment. In this study, it is aimed to reduce the amount of scour occurred at the downstream of the weir by using energy dissipaters with different geometries. The flow and scouring events on the weir were modeled in two dimensions using Computational Fluid Dynamics insert ignore into journalissuearticles values(CFD);. The findings were compared for different downstream conditions and the results were discussed in this respect.
