Abstract
Objective. The aim of the study is to develop a model for the erosion of noncohesive soils that are heterogeneous in size in river beds.
Method. The mathematical model was developed using the theory of probability and the theory of outbursts of random processes, taking into account the normal law of distribution of the horizontal and vertical components of the instantaneous flow velocities and the Rayleigh law for the distribution of their maxima.
Result. Statistical analysis of various models of erosion of non-cohesive soils heterogeneous in size in river channels was performed.
Conclusion. The basic principles of studying various models of erosion of heterogeneous noncohesive soils in river beds, as well as the structure of calculation algorithms and programs compiled on its basis, allow us to continuously improve the calculation method and make adjustments to the corresponding modules of algorithms and programs.
