The paper presents a specific application to a typical Mediterranean landscape (Punta Licosa headland) based on an advanced procedure of the hierarchical, multi-scale, object-based geomorphological mapping system in use at the Salerno University (Italy). The study area is a wide valley head characterized by shallow landslides and active stream erosion affecting Pleistocene landforms produced by diffusive processes (hollows, side-slopes, and noses). Based on simple geomorphometric parameters, from object-based geomorphological map obtained by supervised automatic landforms recognition, spatial analyses on target areas of the landscape have been performed. Results of the above analyses highlighted superposition landform components related to two distinctive morphogenetic controls. The proposed procedure allows the quantitative reconstruction of geomorphic events and scenarios in polygenetic/poly-chronologic landscapes, useful to assessing landslide and erosion hazard in a dynamic way.
