Wadi Sirhan

Wadi Sirhan (Arabic: وَادِي سِرْحَان, romanized: Wādī Sirḥān; translation: "Valley of Sirhan") is a wide depression in the northwestern Arabian Peninsula. It runs from the Aljouf Oasis in Saudi Arabia southeastward into Jordan. It historically served as a major trade and transportation route between Syria and Arabia. From antiquity until the early 20th century, control of Wadi Sirhan was often contested by various Arab tribes. The valley is named after the Sirhan tribe which migrated there in the mid-17th century.
