Wadi Najran
Wadi Najran is a seasonal watercourse in the Kingdom of Saudi Arabia. It is a natural tourist attraction in Najran Province, south of Saudi Arabia, and one of the largest valleys in Saudi Arabia.
Wadi Najran route
Wadi Najran extends for 150 km across Khabash Governorate and Najran City. Flowing from southwest to northeast, it originates in Yemen and empties into al-Rub' al-Khali (Empty Quarter) to the east of Khabash Governorate, with an average gradient of five m.
Wadi Najran tributaries
Wadi Najran is fed by three tributaries: Wadi Al-Hosn, Wadi Al-Ardh, and Wadi Maroon. Wadi Najran Dam, situated along its path, has a storage capacity of around eighty-five million m.
The valley splits Najran City into two sections and serves as the primary water source for the province. Agriculture depends on this water, while the valley also deposits large amounts of silt that accumulate in the plains, flooding the farms along its banks and enhancing their fertility.
