摘      要：This paper numerically investigated the two-dimensional motion of a bead in shallow water down a steep rough bed via smoothed particle hydrodynamics（SPH）.The motivation of this work is to study the mechanism of particle transport in shallow *** simulated results show agreement with the experimental data which also verifies the validity of ***,a series of numerical experiments are carried out to discuss the influences of bead material,slope gradient on the characteristics of bead motion and the state of shallow flow.
