THE CONTRIBUTION OF LANDSLIDES TO LANDSCAPE EVOLUTION IN EUROPE

After a review of some analytical and conceptual models of slope evolu tion with the intervention of mass movements, a proposal is made of a series of indicators for the quantitative description of landscape evo lution in relation to mass movements. The ratio between landslide mobi lisation rate and downwearing rate is proposed as a quantitative measu re of the significance of mass movements in landscape evolution. A sub division of European regions with respect to their susceptibility to l andsliding as a process of landscape evolution is proposed. The role o f landsliding for the evolution of landscape in some regions is descri bed. The data presented show that landsliding may in some cases be the main contributor to landscape change.
