List of wadis of Saudi Arabia

Saudi Arabia does not have any permanent rivers, but it has numerous wadis (valleys), which are riverbeds that are usually dry and only flow after rainfall. Some wadis flow year-round due to the discharge of treated water from wastewater treatment plants.^[1] The longest wadi in the country, which is also the longest in the Arabian Peninsula, is Wadi Ar-Rummah, which runs through multiple provinces.
