Zambezi River Authority It flows south and forms part of the border between Zambia and Namibia. After picking up the waters of the Chobe River at the quadripoint where Zambia, Namibia, Botswana and Zimbabwe meet, the river flows east along the border between Zambia and Zimbabwe, powering the shared Kariba Dam hydroelectric station, before entering Mozambique and flowing to the Indian Ocean. The Zambezi basin also includes parts of Malawi and Tanzania. The Zambezi is the fourth largest river in Africa after the Nile, Congo and Niger.

Zambezi Floodplain, the most notable feature of the upper Zambezi, but this northern part does not flood so much and includes islands of higher land in the middle. Thirty kilometres below the confluence of the Lungwebungu the country becomes very flat, and the typical Barotse Floodplain landscape unfolds, with the flood reaching a width of 25 km in the rainy season. For more than 200 km downstream the annual flood cycle dominates the natural environment and human life, society and culture. Eighty kilometres further down, the Luanginga, which with its tributaries drains a large area to the west, joins the Zambezi.
