The stochastic method based on the concept of contact zone is used for the calculation of particle-bed collision. Some examples of calculation are presented, in particular, the lateral dispersions of the particles, which can be used for the particles sorting. The beams of the trajectories of particles starting their saltation from one point were calculated. It was found that the centrelines of the beams can be approximated by straight lines for low and moderate values of the bed transverse slope and the angles between centrelines and the stream direction depend on the lateral slope of the bed.
