A Random Trajectory Model (RTM) for solid liquid two phase flow based on the Lagrangian Method is presented in this paper. The effects of water drag force, pressure gradient force, buoyancy and virtual mass force on the particles were included and the turbulent dispersion was modeled by random method. Three dimensional k ε model was used to calculate the flow field. A pumped storage power station, with a natural lake as its upper pool, was taken as a case for the study. Averaged movement trajectories, velocities and the volume concentration distributions for 5 groups of sediment particles, were predicted with RTM. The possible silted locations in the lake were also predicted.
