Description :
The mechanism for instability of a cliff made of soil mass due to downcutting was examined through an experiment using a new apparatus having no side walls. The cliff is made by piling an assembly of wetting aluminium rods. The following points can be concluded: 1) shearing failure occurs just after a tension crack develops in association with increasing cliff height; 2) the critical height of a cliff increases with increasing cohesion of the cliff material; 3) the encroachment distance is always smaller than the critical cliff height.
