Basically turbidity flow is two phase flow which one flow move in another flow with different density. This paper presents a series of experiments in which saline gravity currents flowed through a sinuous channel model. This flume contains three successive bends with three different relative curvature radiuses: r/b=2, 4 and 6, 8.5 m length, 20cm width and 70cm height. The results show that the maximum velocity occur in inner bank until center of the bend then tend to outer band and also elevation of the interface at the outer bank is in every case greater than the one at the inner bank. Shear stress changes is in depend on velocity profile and maximum an minimum of it occur in inner and outer bank respectively.In moving bed conditions, generally increasing concentrations and thus increasing the flow velocity, the flow power has also increased and the bed roughness has been changed. Until by washing the form of the substrate, the roughness and shear stress also begin to decrease.
