To predict shear stress distribution on stream boundaries is one of important problems in river hydraulics because shear stress causes erodible materials composing the boundaries to move and channel geometry to change. The boundary shear stress is ordinarily calculated from the streamwise component of weight of water column on boundary segment. This method brings in serious errors in the shear stress near the bank because internal shear stress due to lateral variation of velocity is neglected. In this paper, an accurate expression to shear stress distribution is derived from the formulation of similar cross-sectional profile of widening channel and of bed load on lateral and longitudinal slopes. Successful formulation of shear stress distribution makes possible to predict the channel widening process.
