The diyala ( Arabic نهر ديالى, DMG Nahr Diyālā ; Kurdish : Sîrwan , Persian سيروان, DMG Sīrvān ) is a tributary of the Tigris . The Iranian part of the river is called Sirvan while Diyala refers to the Iraqi section.

It has its source in Iran and flows through Iran and Iraq . Its total length is 443 km. The etymology of the name is unknown. In ancient times the river was known as Σίλλα (Silla) or Δέλαζ (Délaz) . The Iraqi province of Diyala is named after this river.

The source is located near the town of Hamadan in the Zagros Mountains . The Diyala forms 32 km of the Iranian-Iraqi border. The Diyala meets the Tigris south of Baghdad . Only the lower part of the river is navigable and forms an important route for trade between Iran and Iraq. There is a dam on the lower reaches of the Diyala.

The Nahrawan Canal , which began in the 3rd century, and the Diyala have partly swapped their course in the course of the Middle Ages . The underflow of the Nahrawan is presumably the former underflow of the Diyala, whereas the modern underflow of the Diyala probably follows a former tributary of the Nahrawan.

There are several archaeological sites in the area of ​​Diyala such as Tell Agreb , Tell Asmar , Nerebtum and Ḫafāǧī .
