Ar-Rukai

Ar-Rukai lies in the Wadi al-Batin country where inner Arabia meets the plains around Kuwait and southwestern Iraq. Wadi al-Batin is an intermittent river, the lowest and final section of the much longer Wadi al-Rummah system. It crosses the Al-Dibdibah gravel plain from southwest to northeast, following a channel cut before the regional climate became so dry.

The old alluvial fan extends northeast from Hafar al-Batin, showing that water and sediment once spread across this low ground. At the bend called Aujat al-Batin, the wadi marks the meeting of Saudi Arabia, Iraq and Kuwait. Neolithic and later Islamic settlements found on the Kuwaiti side show that the channel long attracted activity. Its margins offered grazing after rain, shallow water and a natural route across an otherwise difficult desert.

Ar-Rukai is best understood as part of this corridor rather than a separately documented city. Wells, temporary pools and pasture governed movement by herders and caravans, while the open gravel plain allowed travel without the obstacles of larger dunes. The place therefore belongs to a long story of seasonal water, grazing and routes linking the Arabian interior with the head of the Gulf.
