Ad-Dibdibah

Ad-Dibdibah is a broad gravel plain in the low desert where northeastern Arabia meets Kuwait and southwestern Iraq. Wadi al-Batin crosses it in a northeast-to-southwest direction. The dry watercourse is the lowest and final section of Wadi al-Rummah, an intermittent drainage system reaching across northern Arabia. Rain rarely runs through the channel, but the surface preserves deposits from earlier floods.

An extensive alluvial fan extends northeast from Hafar al-Batin and may have formed the gravel plain itself. At Auğat al-Batin, the bend of the wadi marks the tripartite meeting of Saudi Arabia, Iraq and Kuwait. The channel has therefore long been both a route across difficult country and a convenient line by which political boundaries could be described. The channel has long served as a natural line between the Kuwait and Iraq regions.

Archaeology reveals much older use. Neolithic sites and settlements from the early through late Islamic periods have been found on the Kuwaiti side. The wadi thus preserves successive ways of living around a watercourse whose flow has faded. Its gravel surface, dry channel and fan-shaped deposits make Ad-Dibdibah a key junction of physical geography and territorial history in the northern Gulf region.
