The Okavango river
The Okavango river basin covers a hydrologically active area of approximately 323 192 km2 shared by three countries in southern Africa: Angola, Namibia and Botswana. The Okavango River is the fourth longest river system in southern Africa, running for 1,100 km from central Angola, as the Kubango, through Namibia to the Kalahari in Botswana. The river rises in the headwaters of the Cuito and Cubango tributaries in the highland plateau of Angola at an elevation of 1780 metres.

It derives its principal flow from 120,000 km² of sub-humid and semiarid rangeland in Cuito-Cubango province of Angola before concentrating its flow along the margins of Namibia and Angola and finally spilling into the Okavango fan or ‘delta’ at an elevation of 980 metres. Several rivers become one as the water moves south and east, branching again when it reaches and ends in the Okavango Delta, one of the largest freshwater inland wetlands on the planet. The river delivers about 10 cubic kilometres of surface flow into the Delta system per annum.
