Objective. The aim of the study is to model erosion processes in open channels. Method. A stochastic approach is applied to the calculation of parameters and the construction of models of individual stages of the erosion process: disruption, weighing and transport of eroded soil particles by a turbulent flow. Result. A technique has been developed for predicting the general erosion of riverbeds and canals, composed of homogeneous and heterogeneous non-cohesive soils. Approbation of the developed technique on the material of laboratory and field studies confirmed its satisfactory accuracy in a wide range of hydraulic conditions and soil granulometric compositions. Conclusion. The principles of developing a model of erosion processes in open channels, the modular structure of the calculation algorithms and programs compiled on its basis, allow us to continuously improve the methods for calculating individual parameters of the erosion process and make adjustments to the corresponding modules of algorithms.
