A stream of treated sewage effluent, flowing 20-30 km south-west from Makkah into the largely flat sandy desert of the Tihamah. The flow is rather erratic, being strongest for the first 12-15 km, after which satellite pools tend to be ephemeral. The water is often densely lined with Calotropis, Phragmites and grasses.
See box for key species. A wide range of ducks and waders uses the site in winter. Other migrants include small numbers of Grus grus and G. virgo. Pterocles lichtensteinii and P. exustus can be very common in the area.
