Abstract: 

This chapter analyzes the effects of wave energy converter farms on storm-induced coastal flooding under three sea-level rise scenarios: present situation, optimistic projection and pessimistic projection. For that, the Delft3D-Wave and XBeach-G models were jointly apply to a gravel-dominated coast in southern Spain. The results show that the wave farm induces redutions, for the three scenarios, in breaking wave heights (about 10% and 25% under westerly and easterly storms, respectively) and total run-up values (8% and 10%, respectively). This leads to reduction in flooded cross-shore distances and dry beach areas. The decreases in flooded dry beach areas for the three sea-level rise scenarios are between 1400 and 3900 m2 under south-westerly storms, and between 2100 and 3400 m 2 under south-easterly storms. Therefore, wave farms are efficient management strategies to mitigate coastal flooding even under sea-level rise conditions.
