The present study investigated the dam break flow containing the particles. To investigate the effect of liquid density, liquid density of wide range is considered in this study. Two region of the overlapping and divergent govern the time evolution of the particles and the free-surface. The overlapping regime shows that the front head positions of the liquid and the particles are almost identical and two dimensional behaviors. However, in the divergent regime, lower liquid densities derive that the front head of liquid is faster than that of the particle. Beyond the critical liquid density, the opposite divergent pattern to the low liquid density appears. Especially, the three-dimension effect on the distribution of the particles and the free-surface appears in the divergent regime.
