Zambezi River

This is the fourth largest river in Africa after the Nile, Congo, and Niger rivers.  The river flows for 2700km.  Rising in the northern corner of Zambia, it turns south flowing through easter Angola and western Zambia, before entering Zimbabwe at Kazangula.  Some 65km east of Kazangula, the river plunges over the Victoria Falls.  It then enters the Batonka Gorges before reaching Lake Kariba and the Kariba Dam.  Flowing through the Kariba gorges and some falls and rapids it reaches Cahora Bassa Lake and dam wall in Mocambique , and thereafter on to its delat mouth on the Indian Ocean near Chinde, south of Quelimane.  The main tribuataries are the hobe, the Kafue, Luangwa, and the Shire River flowing from Lake Malawi.

Several millions of years ago the Zambezi as flowing through a different course which was the Okavango Delta, Makgadikagadi, the Kalahari, and into the Altantic Ocean.  Due to plate movement the outlet to the Atlantic was closed and the Makgadikagadi Pans, Okavango, Savute, and Mababe area became a huge lake.  Afterwards, the Zambezi changes its course in the direction of the present Victoria Falls and the Indian Ocean.  The huge lake started to dry out, forming the numerous Makgadikagadi lakes, Nzai pan, Savute, etc.
