What is Wadi Hanifah?
Wadi Hanifah (Arabic: وَادِي حَنِيْفَة), historically known as Wadi al-Arad, is a seasonal river valley (wadi) located in the Najd region of Riyadh Province. It extends approximately 120 kilometers from northwest to southeast, cutting through Riyadh city and its surrounding towns such as Uyaynah, Irqah, and Diriyah.
The valley serves as a natural water drainage system for an area exceeding 4,000 square kilometers, making it a crucial geographical feature in this arid region. Its fertile soil and water resources historically supported agriculture and settlements, playing a vital role in the development of Riyadh and the Saudi state.
Historical Significance of Wadi Hanifah
- Ancient Roots: The valley was originally known as al-Irdh and later renamed after the Banu Hanifa tribe, prominent during the Islamic conquest of Arabia.
- Cultural Heritage: The emirate of Diriyah, the first Saudi state’s capital, was established on the western banks of Wadi Hanifah, highlighting its historical importance.
- Agricultural Legacy: In prehistoric times, the region experienced heavy rainfall, making the valley fertile and suitable for farming, a fact reflected in local traditions and archaeological findings.
