The present contribution examines the various geomorphological, sedimentological and coastal hydrodymamic conditions that are related to the present erosive situation along the broader coastal area of the N/NW coast of Samos Island. The extended erosion, particularly evident during the past 2-3 decades, is attributed to the rise of sea level (>10 cm over the past 100 years according to IPCC report of 2007) in conjunction with the incoming relatively high wave energy, which favouring the offshore transfer of fine-grained beach material. In addition, the various man-made constructions either inhibit the terrigenous sediment fluxes to reach the coast and/or by altering coastal hydrodynamics contribute to erosion. Finally, the existed defence constructions seem to have served only to the stabilisation of the coastline and not to its natural recovery.
