Mapping of landslide susceptibility of coastal cliffs: the Mont-Roig del Camp case study

摘要: The weathered and fractured conglomerate cliffs of Mont Roig del Camp constitute a rock fall hazard for the surrounding pocket beaches and, therefore, population that frequent them, especially over summer. Landslide susceptibility cliff has been assessed using Rock Engineering System method (RES). determinant triggering factors considered in this study include: wave exposure, shoreline variations, height, slope, geotechnical quality rocky mass, superficial runoff orientations favoring landslides. Geographic Information Systems (GIS) have employed to facilitate information analysis generate new maps. mass orientation are most interactive stability cliff. However, variations surface dominant system. Thus, determined be basic variable characterization because its high dependence on remaining factors. landslide map depicts predominance surfaces with moderate degrees concentrated mainly headlands, where combined actions subaerial marine processes control weathering eroding processes. Therefore, assessment based methodology allowed identification hazardous areas should future management plans.
