Geomorphology of the Ceyhan River lower plain (Adana Region, Turkey)

We present the geomorphological map of the lower plain of the Ceyhan River (Adana province, Turkey). We managed three field campaigns data and remote sensing observations in a GIS environment obtaining a 1:25.000 scale map. The area, mostly formed by alluvial sediments, is characterized by intense fluvial dynamics with superimposed severe agricultural activity. Erosional processes prevail on rocky ridges partially bordering the plain on the north-eastern side. The alluvial plain is flanked by large alluvial fans on its eastern side, whereas the western limit consists in a smoothed and rather undistinguishable watershed. Alluvial and deltaic deposits close to the river mouth are bordered southward by nested coastal dunes, lagoons, swamps and marshes punctuating the coastal belt. This area was a crucial site in the antiquity, as documented by several evidences of settlements from the Neolithic. This map could be a useful instrument to support further archaeological research.
