Investigating the Effect of Circular Bridge Piers on Local Scouring at 60° Channel Junctions Using SSIIM1 3D Numerical Model

Insertion of different water structures such as bridge piers in the flow path contracts the flow cross section and causes backwater at upstream sections. The velocity and turbulence of flow increases around these structures and bed scouring will occur. To discover the effect of different structures...

Summary:Insertion of different water structures such as bridge piers in the flow path contracts the flow cross section and causes backwater at upstream sections. The velocity and turbulence of flow increases around these structures and bed scouring will occur. To discover the effect of different structures in the vicinity of channel junctions on flow and sediment patterns, precise studies should be conducted. The effects of bridge pier on flow and sediment patterns in stright and curve open channels have been investigated (Salaheldin et al., 2004, Tabib zadeh et al., 2005). However, its effect on flow and sediment patterns at open channel confluences has rarely been studied.
