Saudi Arabia does not have any permanent rivers, but does have numerous wadis (valley) which are riverbeds that are either permanently or intermittently dry.
This list is arranged by drainage basin, with respective tributaries indented under each larger stream’s name.
Saudi Arabia has the largest economy in the Middle East, and as of 2018, it was the 18th largest economy globally. Saudi Arabia has no permanent rivers within its border. It is one of the 17 countries in the world without rivers.
Saudi Arabia had deep water holes around the ‘Al-Kharj and lakes at the Layla Aflaj up until the 1980s. They were fed by massive underground aquifers that were formed several millions of years ago. The ‘Al-Kharj was a critical source of drinking water. However, there are Wadis that serve as the source of water. The Wadis refer to a valley or a dry river bed which contain water, especially during the rainy season. Saudi Arabia stores approximately 6 billion cubic feet of water in the more than 200 dams found in the Wadi Bisha, Wadi Jizan, Wadi Fatima, and Najran among others.
