Abstract

Transportation of bed-load is mainly governed by the flow velocity and impinging phenomenon of moving particles on the bed particles. Since the impinging phenomenon has stochastic features, the authers construct the reasonable stochastic model for impingement, and propose the simulation model for bed-load transportation together with the dynamic equations of particle movement in the flow. This model is verified by the experimental data, and the characteristic of transportion mechanism of bed-load is studied by this model.
