Template: Infobox River / Obsolete
The Little Zab and Lower Zab (Arabic الزاب الاسفل, DMG az Zab al - Asfal; persian زاب کوچک; Zab -e Kuchak, Syriac: ܙ ܒ ܐ ܬ ܚ ܬ ܝ ܐ; Zawa takhtaya; Greek Καπρος, Kapros; Latin: Caprus ) is a river and rises in northwestern Iran at an altitude of about 3000 m and ends after about 402 km north of Baiji in the Tigris.
Dorothy Garrod excavated in 1947 by Cambridge University from significant human traces from the Neolithic period in Zarzi in the upper valley, dating to approximately 10,000 BC, about 100 kilometers southeast of Arbil. Braidwood from the Chicago Oriental Institute found in 1951 also Neolithic traces, dating to 6,000 BC In the valley there are also the ruins of Shimurru, a Sumerian city dating from around 3,000 BC
At the small Zab are two dams on the Iraqi side, namely the Dukandamm ( opened in 1959 ) and the Dibisdamm (1965 opened ). Iran, too, is planning more dams to produce electricity.
