2D numerical model of channel bed formed of randomly distributed spherical particles.
Abstract eng: The paper deals with the saltation mode of bed load transport. The saltation process modelling consists of two parts – deterministic motion of the particle in fluid and stochastic process of its collision with bed, which is the stochastic part of a Monte-Carlo simulation. The channel bed is formed by spherical particles of non-uniform size, the distribution of the particles (in the collision place and time) is determined according to Gaussian dense function. The numerical method for a bed forming and determination of collision coordinates and a collision angle is proposed.
