This article reviews the methods for calculating the distribution of river sediments in channels. As a result of the analysis, initial methods for the distribution of sediments on the channels was developed for straight and unstable rivers. A mathematical model that describes the distribution of river sediments during uneven movement in the structures has been developed. The distinctive feature of this model is that the distribution of sediments in the stream depends on the fractions. In the hydraulic structures, a mathematical model of turbulent flow was proposed during the uneven movement and based on this model; a method of calculating sediment distribution was developed in a non-linear motion. Comparative analysis of model of calculation of river sediments in constructions was verified with analysis of natural field conditions. The analysis of the results shows that the difference between the measured values and calculated values is 4-8%.
