Site description A long, narrow, man-made river, the only large-scale freshwater habitat in the Eastern Province, running east-south-east from Hofuf and Abqaiq towards al-'Uqair. It is formed by run-off from al-Hasa oasis and sewage effluent from Hofuf, Abqaiq and numerous small towns, and frequently disappears under sand-dunes, to surface again a few kilometres further on. There are numerous pools of up to c.250 ha, often surrounded by large reedbeds. The rest of the area consists of sandy gravel plain and sand-dunes interspersed with sabkhahs and aeolian sand-fields.
