PROBLEM TO BE SOLVED: To provide a method of determining the optimum charging position of sediment by accurately simulating the movement of the soil by the flow of beach after the sediment dredged from the stacked position of a seabed is charged to a place different from the eroded position. SOLUTION: This method of simulating the movement of particles in a sand recycle comprises the step of setting the geographic conditions and wave conditions at a place where the sand recycle is performed and the initial conditions of the particles, the step of calculating a plane wave field and a beach flow field in the position from the graphic conditions and the wave conditions, the step of calculating an external force field applied to the particles from the plane wave field and the beach flow field, and the step of calculating the moving position of the particles by the external force field through a probability course.
