Nossob River

The Nossob River (also spelled Nossob or Nossop) is a dry riverbed in eastern Namibia, South Africa, and Botswana. It stretches over 740 km and was last inundated in 1989. Nossob camp, located at 25°25′18′′S 20°35′47′′E in the Kgalagadi Transfrontier Park, is named after the river.

The Swart-Nossob and Wit-Nossob, which mean black and white respectively, are the two main tributaries of the Nossob. The eastern slopes of the Otjihavera mountain range, east of Windhoek, are the source of both tributaries. Their respective sources are located at 1,800 m and above 2,000 m above sea level. The two riverbeds meet around 80 kilometers south of Gobabis, which is located on the Swart-bank. Nossob's

The river runs through the villages of Leonardville and Aranos on its way to Union's End, South Africa, from this junction. From Union's End, the river bed that forms the Botswana boundary meanders for over 200 kilometers across the Kgalagadi Transfrontier Park. It reaches the game reserve's southern limit slightly north of Twee Rivieren Camp, near the Auob River's junction.

The Nossob River in the Kalahari is supposed to flow once every century. Water does, however, run deep underground to sustain the grass and camelthorn trees that grow in the riverbed. After big thunderstorms, the Nossob may flow briefly, attracting species to the river.

The Nossob River joins the Molopo River 50 kilometers south of Twee Rivieren. The confluence is still 890 meters above sea level at 26°54′15′′S 20°41′24′′E. The Orange River, which it meets downstream of Augrabies Falls, is a tributary of the Molopo.
