Abstract
This paper deals with the resistance law of open channel flows with suspended sediments over a smooth bed by means of the κ-ε model. The interaction term between the solid and liquid phase is taken into account in the κ-ε equations. The mathematical form of this term is considered by using of motion of a single sediment particle. Calculated results concerning the depth-wise velocity distributions and the friction factor are compared with the previous theoretical and experimental studies. These comparison indicate that the basic equations used here are applicable to the turbulent shear flow with suspended sediments to some extent, though further theoretical investigations of the basic equations are required.
