Title: Zambezi River Authority
Content:  The Zambezi originates in northwestern Zambia, and runs west and then southwest through Angola before reentering Zambia. 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.

Content:   The river rises in a black marshy dambo in dense undulating miombo woodland 50 km north of Mwinilunga and 20 km south of Ikelenge in the Ikelenge District of North-Western Province, Zambia at about 1524 m above sea level. The area around the source is a national monument, forest reserve and Important Bird Area. Eastward of the source, the watershed between the Congo and Zambezi basins is a well-marked belt of high ground, running nearly east–west and falling abruptly to the north and south. This distinctly cuts off the basin of the Lualaba (the main branch of the upper Congo) from that of the Zambezi. In the neighborhood of the

In the Zambezi basin, there are a number of major rivers flowing wholly or partially through Zambia: the Kabompo, Lungwebungu, Kafue, Luangwa, and the Zambezi itself, which flows through the country in the west and then forms its southern border with Namibia, Botswana and Zimbabwe. Its source is in Zambia but it diverts into Angola, and a number of its tributaries rise in Angola's central highlands. The edge of the Cuando River floodplain (not its main channel) forms Zambia's southwestern border, and via the Chobe River that river contributes very little water to the Zambezi because most are lost by evaporation. Two of the Zambezi's longest 
Title: Zambezi
Content:  The Zambezi River (also spelled Zambeze and Zambesi) is the fourth-longest river in Africa, the longest east-flowing river in Africa and the largest flowing into the Indian Ocean from Africa. The area of its basin is 1390000 km2, slightly less than half of the Nile's. The 2574 km rises in Zambia and flows through eastern Angola, along the north-eastern border of Namibia and the northern border of Botswana, then along the border between Zambia and Zimbabwe to Mozambique, where it crosses the country to empty into the Indian Ocean. The Zambezi's most noted feature is 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, the Kariba Dam, which provides power to Zambia and Zimbabwe, and the Cahora Bassa Dam in Mozambique, which provides power to Mozambique and South Africa. There are additionally two smaller power stations along the Zambezi River in Zambia, one at Victoria Falls and the other one near Kalene Hill in Ikelenge District.
Title: Zambezi
Content:  The river flows to the southwest into Angola for about 240 km, then is joined by sizeable tributaries such as the Luena and the Chifumage flowing from highlands to the north-west. It turns south and develops a floodplain, with extreme width variation between the dry and rainy seasons. It enters dense evergreen Cryptosepalum dry forest, though on its western side, Western Zambezian grasslands also occur. Where it re-enters Zambia it is nearly 400 m wide in the rainy season and flows rapidly, with rapids ending in the Chavuma Falls, where the river flows through a rocky fissure. The river drops about 400 m in elevation from its source at 1500 m

From this point to the Victoria Falls, the level of the basin is very uniform, dropping only by another 180 m in a distance of around 800 km. The first of its large tributaries to enter the Zambezi is the Kabompo River in the northwestern province of Zambia. A major advantage of the Kabompo River was irrigation. The savanna through which the river has flowed gives way to a wide floodplain, studded with Borassus fan palms. A little farther south is the confluence with the Lungwebungu River. This is the beginning of the Barotse Floodplain, the most

South of Ngonye Falls, the river briefly borders Namibia's Caprivi Strip. The strip projects from the main body of Namibia, and results from the colonial era: it was added to German South-West Africa expressly to give Germany access to the Zambezi. Below the junction of the Cuando River and the Zambezi the river bends almost due east. Here, the river is broad and shallow, and flows slowly, but as it flows eastward towards the border of the great central plateau of Africa it reaches a chasm into which the Victoria Falls plunge.

Title: Zambezi bream
Content:  The Zambezi bream is found in the upper and middle catchments of the Zambezi River system in Zambia, Zimbabwe and Namibia, in the upper Save River and upper Runde River in Zimbabwe and in the Chobe River, Okavango River and Cunene River in Botswana, Namibia and Angola. A population in the Mwekera, a tributary of the Kafue River may represent a separate species. Although some sources state that it is absent in the Cunene.
