The Great Zab River has a course of almost 400 kilometers and is categorized as the most water-rich and substantial tributary that feeds the basin of the Tigris River. Its primary geographical sources are located deep inside the Hakkari mountainous perimeter in the southeastern section of Turkey, at an altitude close to the value of 3,000 meters. Its course transits steep-walled defiles and hard-to-reach canyons, heading towards the Iraqi border, where it later crosses the Kurdistan administrative region. The catchment basin of the Great Zab totals a geographical area of approximately 26,200 square kilometers and receives enormous flows of water resulting from the rapid melting of the alpine snow layer during the spring. The tributary makes the connection with the Tigris riverbed at a distance of about 50 kilometers south of Mosul.
