The paper discusses first the effect of rainfall on the stability of slopes and it focusses on the role of permeability. Existing or induced discontinuities are shown to have a remarkable effect on the slope safety. Also, the relevance of changes in hydraulic properties in weathered profiles is discussed through a real case. The performance of modern “Lagrangian particle” methods and their capabilities to deal with large displacements is presented. The cases solved refer to brittle materials, a common situation in overconsolidated high plasticity clays.
