Abstract

The Canary Islands have a long coastline with varying levels of exposure to severe sea conditions. Frequent states of alert and emergency in some parts of their coastline are commonly related to the occurrence of extreme wave conditions. Among the phenomena directly driven by the waves when reaching the shore are the wave run-up and overtopping. Both the study of the flood level, including its variability, and the associated risks are key tools in the planning and management of coastal zones. The aim of this research is to examine the probability of occurrence of run-up events capable of exceeding different topographical levels, for estimating the risk level associated with flooding of the different areas in which the Boca Barranco Beach can be divided, in terms of their nature and use. This beach is located on the island of Gran Canaria, Spain, and is part of the site of scientific interest of Jinámar. A large wave dataset is used as input to a high-resolution numerical model for propagating offshore wave conditions to shallow waters in the study area. Furthermore, the morphology of the study area is reproduced by combining different bathymetric databases. Finally, the probability of occurrence of different levels
