Understanding the processes that govern transformation of landscape through time is essential for exploring evolution a coastal area. Coastal landscapes are dynamic sites, with their strongly linked waves and sea-level variations. Geomorphological features in area, such as beachrock formations dune fields, can function indicators time. However, our knowledge chronological framework deposits on Aegean coasts limited. Optically stimulated luminescence dating techniques deemed to be very promising indirect sediments, especially when they archaeological evidence. The sediments from different sediment core depths, determined by method luminosity, allows us calculate rate deposition over Additionally, stability were studied 1945 until today, use aerial photographs satellite images. This paper presents 6000 ka years based geomorphological, archaeological, radio-chronological data. Based results, early stages Ammoudara beach field appear formed ~9.0 – 9.6 BP, while OSL ages 6 m depth represented timing its stabilization (OSL ~5–6 ka). indicates appears already have been long before Bronze Age (5-10 BP) became stabilized only localized episodes reactivation occurring, high erosion rates found modern times.
