	abstract = {<div>The 7 kilometers long coastline of Marathon Gulf (East Attica, Greece), has been chosen for this\&nbsp;study, in order to classify its coastal erosion, using the Coastal Vulnerability Index (CVI) through GIS\&nbsp;technology, since several incidents of erosion have been identified during the past decades in the area.\&nbsp;The CVI index is used for assessing the vulnerability of a coast to an anticipated future sea-level rise.\&nbsp;It relates geological (coastal geomorphology, historical changes of coastline{\textquoteright}s position, coastal slopes)\&nbsp;and oceanographic (wave height, run up and tidal range) variables in a semi-quantitative manner. We\&nbsp;combined different kinds of datasets extracted from high resolution panchromatic aerial photographs\&nbsp;of several time periods (1960-2010) and traced the contemporary shoreline by high accuracy\&nbsp;surveying with Real Time Kinematic (RTK) GPS equipment. The interpretation of all shorelines\&nbsp;required geo-statistical analysis in a Geographical Information System, in order to estimate the rate of\&nbsp;shoreline change for a period of 53 years.\&nbsp;Retreating rates were calculated for each section reaching the value of 0.6 m/yr. According to the\&nbsp;produced CVI values (10.61- 39.52), it is found that 46\% of the coast has very high vulnerability, 20\%\&nbsp;high vulnerability, whilst 29\% have low vulnerability. The area named {\textquotedblleft}Plesti{\textquotedblright} at the southern part of\&nbsp;the study area, a large segment at the coast of Nea Makri, the northern part of Agios Panteleimonas\&nbsp;beach and the eastern estuary of the Inois river are those with the higher risk. These conclusions are in\&nbsp;full agreement with the field observations.</div>},
