Özet

In the present paper, several physico-chemical characteristics of dune sands in a rapidly prograding delta environment on the east coast of the Saros Gulf, northwest Turkey, are presented. For accurate characterization and classification of coastal dunes 4 km long and maximum 500 in wide, the pH, CaCO3 content, electrical conductivity, organic matter content, and x-ray fluorescence spectroscopy data were assessed. In terms of dune classification, our results showed the presence of three distinctive coastal dune types: (1) foredune, (2) semistable gray dune, and (3) stationary dark dune. Field observations combining with aerial photo and satellite image interpretations for the period between 1962 and 2007 also revealed dune loss and migration in the dunefield as a consequence of bidirectional effects of southwesterly and northwesterly winds and wind-force rise of lagoon waters.
