The&amp;nbsp;fieldwork was conducted in April 2018 and September 2018 including mapping of beach&amp;nbsp;morphology in seasonal scale through topographic monitoring of shoreline, coastline and&amp;nbsp;fixed cross sections in the sites under investigation using a differential GPS. In addition,&amp;nbsp;sediment sampling was carried out along selected cross sections in beaches of Mylopotas&amp;nbsp;(three) and Manganari (two). Grain size analysis and statistical processing were realized to&amp;nbsp;reveal spatial and temporal changes of sediment parameters, such as sorting, skewness,&amp;nbsp;mean and kurtosis. The results indicate a rather homogenous grain size distribution at each&amp;nbsp;study area, with the majority of samples being classified as slightly gravelly sand. DGPS&lt;/div&gt;
&lt;div&gt;measurements of shoreline position in Manganari Beach indicate changes that vary between&amp;nbsp;2.50 m and 4.70 m, with the maximum displacement to be observed in the southern part of&amp;nbsp;the beach, where the shoreline is retreated during spring period. Seasonal variations of&amp;nbsp;shoreline position in Mylopotas Beach are up to 4.50 m with the shoreline to be advanced&amp;nbsp;during spring period in the southern and northern part of the beach, while the minimum&amp;nbsp;changes are measured in the central part, where a beachrock formation occurs. Occasional&amp;nbsp;human interferences, such as small-scale beach restoration and nourishment projects,&amp;nbsp;installation of leisure facilities and reshaping of sand dunes, conducted mainly during spring&amp;nbsp;period, alter the coastal sediment budget and transport reinforcing shoreline retreat.&lt;/div&gt;</style></abstract></record></records></xml>
