Abstract
This study involves the geomorphological and morphotectonical Investigation of the Tawuq sub-basin located at the Kirkuk Governorate in North Iraq. The geomorphological analysis and mapping of the area was carried out using aerial photographs and geological data landforms were classified into three groups depending on their shapes and formation processes such as the denudational- structural, denudational, and fluvial. The longitudinal profile analysis of the Tawuq Chai River revealed that the structural and lithological factors were controlled by the changes in the river gradients as the result of the tectonic activity.
