چکیده مقاله
In this research, a bend channel with a 180 degree central angle curvature radius to channel width equal to 2 was designed and built in the hydraulic laboratory of Persian Gulf University in order to help better understand complicated flow pattern in a sharp bend Vectrino velocimeter was employed to measure velocity components and determine bed shear stress This paper studied the effect of the length of L shaped spur dikes on the Reynolds shear stress variations The results of such experiments indicated that a 67% increase in spur dike length would cause bed shear stress to increase by about 53%
