This study aims at integrating the natural and anthropogenic factors a/fecling the Korissia lagoon. It is a shallow coastal lagoon, communicating with the sea via an artificial channel. The area around the lagoon consists o.j' alluvial sediments hosting, in places, newly formed and/or "old" (pre - Holocene) sand-dunes, The broader area constitutes a post alpine sedimentOl)' hasin characterised by smooth morphological reliet' The lower stratigraphic unit of the post-alpine sequence L\ a Pleistocene marly formation, which was detected as the hasement (5-15 Ohm,m) by the geophysical survey.
