Abstract
The instability of a granular slope, with seepage flow and low tail downstream water level, has been experimentally investigate to point out the conditions associated to the formation of a debris flow, excluding the case of the debris flow triggered by a failure due to the toe erosion. Material employed were uniform glass spheres (d = 0.003 m) and two different gravel (d50 = 0.007 m and d50 = 0.0022 m).
