The effect of non-uniformity on the shear stress distribution in open channels was investigated using a polynomial approximation of the shear stress profile. The features of the shear stress distribution were revealed in non-uniform gradually varied turbulent and laminar flows in open channels. The parameter of non-uniformity determining the shape of the shear stress profile in accelerated and decelerated flows was obtained. It was revealed that in the accelerated flow, the shear stress reaches its maximum at the bottom, while in a decelerated flow, it can be maximal both at the bottom and at some distance from the bottom.
