Abstract

The coastal line of Ceuta is more than 25 km length, where a great amount of population is placed. Along this coast many geological processes have been described and imply a great threat for both human and infrastructure. The aim of this work is to analyse these processes by means of geological hazard mapping focused on flooding and flash flood, landslide and rock fall, storms, tsunamis and sea-level rise. These maps are valuable tools to predict and reduce the response-time with respect to catastrophic natural processes and territorial management. Although approximately only 15% of the Ceuta territory is exposed, more than 70% of its coastal area is exposed to geological hazards. Zones of higher hazard are located where several -high to very high degree- hazard processes could take place even simultaneously. This scenario is mainly found in relatively flat coastal sectors but attached to steep zones, where stream mouths and gorges are placed and display a strong seasonal behaviour.
