Departamento de Ingeniería Civil, Escuela Politécnica Superior, Universidad de Alicante, Spain ABSTRACT: Various studies indicate that most of the slope instabilities affecting heterogeneous rock masses are related to differential weathering and erosion of the lithologies that outcrop in the slope. However...
