This paper presents a stochastic, discrete fracture model to investigate the distance-dependent dispersion phenomenon in fractured rock. Under imposed boundary conditions, the dispersion behavior of particles is observed. Simulated results demonstrate that the coefficient of anisotropic dispersion tensor increases with an increasing traveled distance. The anisotropic ratio of dispersion tensor is small and almost increased linearly with migration distance at early migration. The anisotropic ratio has the trend to maintain constant or small variation after a specifietl migration distance. It was also noted that the plume of particles is elliptic.
