Wadi al-Rummah

Wadi Al-Rummah or ar-Rummah is one of the Arabian Peninsula's longest river valleys, at a length of almost 600 km. Now mostly dry and partly blocked by encroaching sand dunes, the wadi arises near Medina at Jibāl al Abyaḑ. It heads towards the north-east, connecting to several smaller wadis, like Mohalla Wadi and Murghala Wadi to the north and Jifn Wadi and Jarir Wadi to the south. It ends at Thuayrat Dunes of the ad-Dahna Desert in Al-Qassim Province near Buraidah. ()
