The NossobRiver (also Nosob or Nossop; ǂnuse ǃab, Khoikhoi for black river) [1] is a dry river bed in eastern Namibia and the Kalahari region of South Africa and Botswana. It covers a distance of 740 km [2] and last flooded in 1989. The river also lends its name to Nossob camp ( 25°25′18″S20°35′47″E / 25.42167°S 20.59639°E ) in the Kgalagadi Transfrontier Park. [2]
The Nossob has its origin in two main tributaries, the Swart-Nossob and Wit-Nossob, meaning black and white respectively. Both tributaries have their origins in the eastern slopes of the Otjihavera mountain range, east of Windhoek. Their sources are at 1,800 m and over 2,000 m above sea level respectively. The two river beds have their confluence some 80 km south of Gobabis, which is situated on the bank of the Swart-Nossob.
From this confluence the river course passes the settlements of Leonardville and Aranos to arrive at Union's End, South Africa. From Union's End the river bed, forming the Botswana border, meanders through the Kgalagadi Transfrontier Park for a distance of over 200 km. It reaches the southern boundary of the game reserve just north of Twee Rivieren Camp, near its confluence with the Auob River.
In the Kalahari, the Nossob is said to flow about once a century. However, water is stored underground to provide life for grass and camelthorn trees growing in the river bed. The Nossob may flow briefly after large thunderstorms, causing wildlife to flock to the river.
The Nossob ends at a confluence with the Molopo River some 50 km south of Twee Rivieren. The confluence at 26°54′15″S20°41′24″E / 26.90417°S 20.69000°E is still 890 m above sea level. The Molopo is a tributary of the Orange River, which it meets downstream of Augrabies Falls.
The Oanob River, a tributary of the Auob River features two dams:

The Kalahari Basin, also known as the Kalahari Depression, Okavango Basin or the Makgadikgadi Basin, is an endorheic basin and large lowland area covering approximately 725,293 km2 (280,037 sq mi) — mostly within Botswana and Namibia, but also parts of Angola, South Africa, Zambia, and Zimbabwe. The outstanding physical feature in the basin, and occupying the centre, is the large Kalahari Desert.
The wildlife of Botswana refers to the flora and fauna of this country. Botswana is around 90% covered in savanna, varying from shrub savanna in the southwest in the dry areas to tree savanna consisting of trees and grass in the wetter areas. Even under the hot conditions of the Kalahari Desert, many species survive; in fact the country has more than 2500 species of plants and 650 species of trees. Vegetation and its wild fruits are also extremely important to rural populations living in the desert and are the principal source of food, fuel and medicine for many inhabitants.

The mole snake is a species of snake. It has been placed in the family Lamprophiidae, and more recently in the family Pseudaspididae, along with the genus Pythonodipsas. It is native to much of southern Africa, and is the only member of the genus Pseudaspis. A study showed that P. cana is caught and consumed by the honey badger, among other species. Remains of the mole snake were found in the faeces, and suggest the consumed individuals were larger specimens.
