Alwand River
river in Iran and Iraq
The Alwand or Halwan (Arabic: نهر حلوان, Kurdish: Çemê Elwen ,ڕووباری ئەڵوەن, Persian: رود الوند) is a river in eastern Iraq and western Iran. It rises in the Zagros Mountains in Iran.
The river flows west from the mountains to the city of Qasr-e Shirin, where it turns south and crosses the border with Iraq. It then divides the city of Khanaqin in two parts. It has played a significant role in land cultivation and in establishment of a strong rural society in the area, and is considered by the people of Khanaqin a symbol for their unity and Kurdish identity.
The river joins the Diyala River at Zengabadh.
