The wadi is inhabited by the Oulad Tidrarin Sahrawi tribe.
Occupying the northern part of Western Sahara, it lay between the 26th parallel north and 27°50'N.
Its colonial capital was El Aaiún (Laâyoune),[2] and it also included the city of Smara.
The territory takes its name from an intermittent river, the Saguia el-Hamra, the route of which runs west from south of El Farsia to reach the Atlantic at Laayoune.
The area is roughly 82,000 km (51,000 mi), making it approximately a third of the entire Western Sahara.
