This study aims to analyze the geomorphological and geological features of Duhok Dam's sites and interpret the landforms and geological structures in this area. Field (observation) investigation, Satellite images and the data obtained from previous studies of this area have been facilitated in this study to make a compilation with each other to conclude a geological and geomorphological interpretation of landscapes. A Geomorphological map is prepared of the most dominant features. The Germawa strike-slip faults and their relation with the gully Duhok strike-slip fault are determined by their effect on the dam site. Sediments from erodible formations could decrease the dam reservoir capacity and flood waves during heavy rain and snow season could impact high pressure on the dam body so several sites were suggested to construct precautionary dams in anticipation of these risks. A seismotectonic situation for the dam area was also studied and determined, requiring officials to continuously monitor the dam body and its foundation.
