摘要

The present contribution provides an initialassessment of the impacts of the longterm (climatic, i.e.sea level rise) and episodic (meteorological) on the sandybeach zone along the coast of Katerini region (NW AegeanSea). Thus, the future retreat of the coastline, due to sealevel rise (SLR) induced by climate change, has beenestimated on the basis of an ensemble of 5 coastalmorphodynamic models. Model's outputs showed thatshoreline retreat range between 7.9-27.3 m and 23.5-70.0mfor SLR of 0.38m and 1.0m, respectively. An initialassessment of coastal flooding has been examined afterconsideration of the astronomical tidal range, storm surgeestimates and calculations of wave runup for intensivewave conditions (Ho>4 m). The results showed that thelocations adjacent to Paralia and Olympiaki Aktiresidences are the most vulnerable to coastal flooding,whilst in the case of future sea level the study area couldbe subjected to coastal flooding.
