BBC Natural World - Zambezi (2012)
The Zambezi (also spelled Zambeze and Zambesi) is the fourth-longest river in Africa, and the largest flowing into the Indian Ocean from Africa. The area of its basin is 1,390,000 square kilometres (540,000 sq mi), slightly less than half that of the Nile. The 3,540-kilometre-long river (2,200 mi) has its source in Zambia and flows through Angola, along the borders of Namibia, Botswana, Zambia again, and Zimbabwe, to Mozambique, where it empties into the Indian Ocean.
The Zambezi's most well-known feature is the Victoria Falls. Other notable falls include the Chavuma Falls at the border between Zambia and Angola, and Ngonye Falls, near Sioma in Western Zambia.
There are two main sources of hydroelectric power on the river. These are the Kariba Dam, which provides power to Zambia and Zimbabwe and the Cahora Bassa Dam in Mozambique which provides power to both Mozambique and South Africa. There is also a smaller power station at Victoria Falls. (www.wikipedia.org)
