The main causes of coastal erosion are anthropogenic.This paper focuses most intently on the geomorphological and sedimentological dynamic processes of the Bay which&amp;nbsp;forming the current situation. For this reason a number of tasks took place in order to determine the level of disturbances&amp;nbsp;of this dynamic equilibrium. This study included two phases of survey for two different periods (summer/winter). The&amp;nbsp;first phase deals with the geomorphological and sedimentological coast characteristics, and includes: i) long-term&amp;nbsp;geomorphological evolution of the coastal zone through the analysis of satellite images (Google Earth), in order to&amp;nbsp;estimate the intensity of coastal erosion. ii) topographic sections at the surface of the coastal zone, through D-GPS (Spectra&amp;nbsp;Precision SP80 GNSS Receiver), perpendicular to the coastline, iii) sediment sampling in the subaerial coastal area, iv)&lt;/div&gt;
&lt;div&gt;analytical recording and mapping of the summer and winter shorelines via the D-GPS, v) the situation of the potential&amp;nbsp;feeders of the shore with materials, necessary for the formation of an alluvial beach, and vi) recording of land uses (Fig.1).&amp;nbsp;The second phase, includes the geomorphological and sedimentological characteristics of the marine area, in particular:&amp;nbsp;i) topographic sections of the bottom surface until the depth of 1.5 m, through D-GPS, perpendicular to the coastline ii)sediment sampling in the subaquatic marine area, iii) data of the numerical recomposition of the wind and wave conditions&amp;nbsp;of the study area, iv) bathymetric eco-sonar data (Lowrance LCX-15MT), v) side-scan single beam eco-sounder (StarFish&amp;nbsp;450), to determine the seabed morphological features of the bay and, vi) substrate component mapping (Fig. 1).&amp;nbsp;Laboratory analyzes were followed by the methods of dry granulometry, in order to categorize it, in different types on the&amp;nbsp;basis of Folk &amp;amp; Ward (1957) method through GRATISTAT (v.8) software.&lt;/div&gt;</style></abstract></record></records></xml>
