The paper considers a stationary translational sediment carrying flow. Correlation with experimental data enables to single out reliable solutions from a number of traditional ones which are based on the concept of equality of moment transfer and sediment diffusion coefficients. By making use of energy considerations it becomes possible to delineate the area of applicability of the traditional diffusion model. An empirical expression is proposed to describe the distribution of concentration in the near-bottom region. The combination of the singled out solution of the diffusion model with this empirical relationship allows to compile an expression describing the distribution of concentration over the entire depth of the flow, and to offer a suitable calculation procedure.
