Abstract

In this paper a phased methodology of risk assessment associated with the occurrence of landslides in the rocky cliffs along the coast between Sines and Zambujeira do Mar is proposed. In order to do so, a surveying on potential risk areas already diagnosed by ARH-Alentejo, now a part of the Portuguese Environmental Agency, was performed. Field observations were made during the time gap of 2010-2013, so as to assess the geotechnical and geological characteristics of the rock masses and evidence of instability mechanisms, as well as the associated preliminary risk. In a second phase, the preliminary risk was re-assessed at prioritized areas while commenting on possible mitigation measures.
