Geomorphology and Dynamics of the Aegean Coasts
摘要
The coastline of the Aegean Sea has a length of about 13,660 km, which belongs to Greece by 78.6% and to Turkey by 21.4%. The Greek coasts consist of hard rocks (43.0%), soft rocks (47.8%), and non-cohesive sediments (9.3%). Most depositional coasts are located in the northern Aegean, where relatively large rivers form extended deltas. At the same time, numerous small beaches (<1 km long) are situated between the rocky promontories of the eastern and northeastern islands. About 28% of the coastline is subject to erosion, with an average retreat rate of 0.3–0.5 m year−1. As sea levels are expected to rise in the coming years due to climate change, immediate action must be taken to increase the resilience of low-slope beaches.
