The Omaruru River is a major river crossing the Erongo Region of western central Namibia from East to West. It originates in the Etjo mountains, crosses the city of Omaruru and reaches the sea a few kilometers north of Henties Bay.[1]
The Omaruru is an ephemeral river with a mean run-off of roughly 40 million cubic metres per annum. Its palaeochannels form an underground delta of the Namib Desert.[1]
