Flow pattern in a channel bend central angle of 90 ° (wide arc radius ratio (3 = (R / B))), rigid bed with lateral intake at the locations (30,45,60) degrees of arc, using Fluent software. Has been studied In this study,turbulentflow, three-dimensional and constant is assumed RSM turbulence model and the equations used to model the Reynolds stresses. The results show that location is the most suitable location for the intake side is 60 degrees. In this location, the width of the separation zone inside the lateral intake and sediment enters the intake is reduced.
