All cohesionless soils assume an angle of repose. On the other hand, when the soil possesses some cohesion the natural slope can be made steeper. A study of the phenomena and mechanics involved in the failure of earth slopes is reported in this paper. In the model studies of sand slopes used to investigate the slide phenomenon, the angle of repose of cohesionless soil was found to be an entirely superficial phenomenon and independent of the height of the slope. However, the inclination and the height of a bank of cohesive soil were found to depend upon cohesion. A technique to create an equivalent cohesion in a cohesionless soil was developed to reproduce actual sliding failures on a smallscale model. These laboratory failures were found to be remarkably similar to those observed in nature; and they proved ideal for studying the mechanics of failure.
