This article discusses granular flow on an inclined plane. Granular flow is modeled on the principles of conservation of mass and conservation of momentum. The equation obtained has a form resembling the equation of shallow water with friction and plane slope effects. This equation is solved numerically by a conservative momentum scheme on a staggered grid. The results show that this method is able to simulate the landslide phenomenon. Comparison with the analytical solution shows that this method is better if given a smaller spatial step.

granular flow, shallow water equations, roll waves.
