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.
