Abstract

The Sharifabad region in the northwest of Iran has responded to ongoing tectonic deformation and has shown characteristic geomorphological features. Due to Arabian–Eurasian collision the uplift and lateral tilting occurred in the study area manifested in avulsion, truncated streams and oriented drainage network. Such geomorphic features have been identified on the satellite images and interpreted through DEM and field observations. The fluvial features in the study area show uplift in one side of the Ghezel Ozan River which is caused lateral tilting in the area.
