TRANSITIONAL IMPACTS OF ENSO ON WAVE CLIMATE IN COASTAL REGIONS. (2020). Coastal Engineering Proceedings, 36v, waves.22.


Amongst all the factors involved in coastal risk assessment, climate variability is key, due to its potential for modifying the coast, particularly through increased seasonal risk of erosion-flooding on the coast (Toimil et al. 2020; Wahl and Plant 2015). The principal driver of interannual variability of the wave climate around the world is El Nio-Southern Oscillation (ENSO). Many researches have focused on the analysis of this phenomenon globally ( Stopa and Cheung 2014), its impacts on regional wave climate (Barnard et al. 2015, 2017; Oderiz et al. 2020; Reguero, Mendez, and Losada 2013) and their local coastal effects ( Mortlock and Goodwin 2016). This interest in ENSO impacts in wave climate is motivated by its capacity to cause coastal erosion (Barnard et al. 2015). Particularly, the temporal and spatial transition of ENSO is nowadays a current issue (Ha et al. 2012). On the worlds coasts, the ENSO impacts delay is not yet fully understood, nor integrated into engineering practices.
