The characteristics of clastic grain flow along a non-uniform slope have been discussed based on the controlling equation presented by Savage. The effects of bed friction coefficients
internal friction angles of clastic flow
initial velocity and the slope angle are mainly analyzed. It is shown that the movement of clustic flow is obviously different under different combinations of factors. The internal friction angle and the slope angle affect the movement configuration and the maximum movement distance obviously. However
the bed friction affects the maximum distance little because it only affects the grains near the bed.
