The Swakop River is a major river in western central Namibia. Its source is in the Khomas Highland. From there it flows westwards through the town of Okahandja, the historic mission station at Gross Barmen, and the settlement of Otjimbingwe. It then crosses the Namib desert and reaches the Atlantic Ocean at Swakopmund. The Swakop is an ephemeral river; its run-off is roughly 40 million cubic metres per annum.
