Abstract: A depth-averaged model has been introduced for simulating the velocity distribution in curved open channels. The mathematical model consists of the depthaveraged moment of momentum equations and predefined velocity profiles. Based on the moment of momentum depth averaged model, simple equations for the estimation of the surface velocity and bed shear stress in radial direction in curved open channels are developed. The bed shear stress can be estimated by the product of the secondary surface velocity, channel roughness and a roughness dependent constant. Comparisons with experimental results are included.
