Abstract

The aim of these experiments is to observe directly the processes of granular flow interaction with various erodible and inerodible runout path conditions. Substrate materials with the least frictional resistance showed the greatest response to granular flow overriding, producing the longest runout observed with a unique deposit profile shape. With a smooth substrate basal contact, failure occurred along this plane and avalanche and substrate became coupled during runout. Reducing substrate thickness diminished the effect of basal contact roughness on granular flow runout and deposit length. Inerodible, non-deformable substrate conditions caused changes in granular flow behaviour from essentially en masse sliding on low-friction surfaces to increasing granular agitation over rougher paths
