Approximate position of the Hezil Suyu river (red line) tributary of the Little Khabur river (green line).
|Hezil Suyu river is not to be mistaken with the Little Khabur river|
The Hezil Suyu (or Hezil Çayı or the Nizil river, in Turkish language suyu means water of) is a river in south-eastern Turkey in the Eastern Anatolia Region which flows entirely in the Şırnak Province and is part of the natural border between Turkey and the Kurdistan region of Iraq. Just before it forms the border, it is dammed by the Silopi Dam. Just west of the city of Zakho in Iraq, it joins the Little Khabur river, which then forms the border.
The Hezil Suyu river is not to be mistaken with the Little Khabur river which is tributary to the Tigris river and flows east of Zakho city and goes through the Zakho city joining its tributary the Hezil Suyu west of Zakho city.
- Panoramio map which calls the Little Khabur river with the name of Hezil Suyu but this river is actually the Little Khabur river which is tributary to the Tigris river.
- Panoramio map showing the confluence between the two rivers. The river crossing the city of Zakho in Iraqi territory is the Little Khabur river not the Hezil Suyu river.
