Weathering includes all the processes of chemicalalteration and physical breakdown of rock masses at, or near, the Earth's surface. Intense and/or continuous weathering processes may result in thick sequences of complex and heterogenous materials characterized by physical and geotechnical properties which have been strongly altered by the action of weathering. As a consequence, they may be prone to slope failures,erosion and landslides. In addition, availability of large amounts of weathered materials and loose debris in catchment basins may represent a serious hazard during, or following, intense rainfall, contributing significantly to the transport of sediment and debris during floods.
