Abstract: In this work an integrated methodological approach for the upgrading of coastal structures due to climate change impact is presented. The methodology includes the definition of the performance criteria of the structures and the specification of the climate change scenario for the structure' s service lifetime. Various concepts for upgrading existing emerged and submerged rubble mound breakwaters are studied and related costs are estimated. The proposed methodology is implemented for two specific coastal structures, located in Northern Greece; the rubble mound breakwater in the Port of Alexandroupoli and the submerged breakwaters in Paralia Katerini. It is shown that the influence of climate change is stronger in terms of sea level rise rather than the increase of the wave heights. Therefore the structures that are studied fail to fulfill the criteria related to wave overtopping and transmission but satisfy the stability criteria, under the climate change scenario. The final selection takes into account the upgrading costs for each alternative.
