Abstract:

Naxos is the largest island (430km2) οf Cyclades complex. The relief of the island is mountainous, with a central mountain chain crossing it from the north to the south.
The geology of Naxos is characterized by a migmatite irruption, metamorphic rocks (schist, gneiss, marble), and sedimentary rocks (Neogenic and Quaternary deposits). Erosion is a complex procedure, which takes place after the forming of
weathered surface material. In this study, an erosion risk map was created, with the use of GIS technology. For this purpose, the maps and fieldwork data concerning the geology of the island, as well as the topography and the geomorphology (of the area) were imported into the GIS. Subsequently, the input data of the final thematic
map were modified with the use of fuzzy logic rules, which was considered to be
necessary because of the nature of the studied variables.
