Botswana - April 28th, 2012

Many bodies of water, different in size and hydrology, can be observed in this image of Angola (upper left), Zambia (upper right), Botswana (lower left) and Zimbabwe (lower right).

Visible by the right edge is the dark blue Lake Kariba, located on the border between Zambia and Zimbabwe. It is the world’s largest artificial reservoir by volume. Southwest of the lake is the Makgadikgadi Pan, in Botswana, the world’s largest salt flat complex.

In the center of the image is the Caprivi Strip, a narrow protrusion of Namibia eastwards about 450 km (280 mi), between Botswana to the south, Angola and Zambia to the north, and Okavango Region to the west. Caprivi is bordered by the Okavango, Kwando, Chobe and Zambezi Rivers.

To the west is the Okavango Delta, formed where the Okavango River empties onto the Kalahari Desert. To the north is the Barotse Floodplain, which begins by the Zambezi River’s confluence with the Kabompo and Lungwebungu Rivers in the north. The region is a flat plateau at an elevation of about 1000 m tilting very slightly to the south.

Lake Kariba on Zambia-Zimbabwe Border

Zimbabwe and Zambia - March 1st, 2012

Lake Kariba is the world’s largest artificial lake and reservoir by volume. It lies 1300 kilometers upstream from the Indian Ocean, along the border between Zambia and Zimbabwe. Lake Kariba was filled between 1958 and 1963 following the completion of the Kariba Dam at its northeastern end, flooding the Kariba Gorge on the Zambezi River.

Lake Kariba is over 220 kilometers (140 mi) long and up to 40 kilometers (20 mi) in width. It covers an area of 5,580 square kilometers (2,150 sq mi) and its storage capacity is an immense 185 cubic kilometers (44.4 cu mi). The mean depth of the lake is 29 meters (95 ft); the maximum depth is 97 meters (320 ft). It is the world’s largest human-made reservoir. The enormous mass of water (approximately 180,000,000,000,000 kilograms, or 180 petagrams [200 billion tons]) is believed to have caused induced seismicity in the seismically active region, including over 20 earthquakes of greater than 5 magnitude on the Richter scale.

Barotse Floodplain on Zambezi River in Western Zambia

Zambia - January 6th, 2012

The Barotse Floodplain, visible as a bright green area by the Zambezi River on the left side of this image, is one of Africa’s great wetlands and a designated Ramsar site. It is located in the Western Province of Zambia. The region is a flat plateau at an elevation of about 1000 m tilting very slightly to the south. The Zambezi and its headwaters rise on the higher ground to the north, which enjoys good rainfall (1400 mm annually) in a rainy season from October to May.

The floodplain stretches from the Zambezi’s confluence with the Kabompo and Lungwebungu Rivers in the north, to a point about 230 km south, above the Ngonye falls and south of Senanga. Along most of its length its width is over 30 km, reaching 50 km at the widest. The main body of the plain covers about 5500 km², but the maximum flooded area is 10 750 km² when the floodplains of several tributaries are taken into account.

Cahora Bassa Lake on Zambezi River, Mozambique

Mozambique - December 24th, 2011

Parallel to the top edge of this image is the Cahora Bassa lake, Africa’s fourth-largest artificial lake, situated in the Tete Province in Mozambique. In Africa, only Lake Volta in Ghana, Lake Kariba, on the Zambezi upstream of Cahora Bassa, and Egypt’s Lake Nasser are bigger in terms of surface water.

The lake is situated on the middle section of the Zambezi River. The middle segment ends where the river enters Lake Cahora Bassa. Formerly the site of dangerous rapids known as Kebrabassa, the lake was created in 1974 by the construction of the Cahora Bassa Dam. Most of the electricity generated by Cahora Bassa, is sold to nearby South Africa.

Sediments from Zambezi and Buzi Rivers, Mozambique – July 18th, 2011

Mozambique - July 14th, 2011

The Zambezi and Buzi Rivers empty into the Mozambique Channel and Indian Ocean in this image of southern Mozambique. Here, the mouth and estuary of the Buzi can be observed just north of the patch of clouds at the bottom left. The mouth of the Zambezi is visible further up the coast, near the image center.

The Zambezi River divides Mozambique into two topographical regions. To the south of the river, visible here, are broad lowlands, with the Mashonaland plateau and Lebombo mountains located in the deep south.

The Buzi River (Portuguese: Rio Búzi) flows eastward through the Manica and Sofala provinces of Mozambique. It then empties to the Mozambique Channel west of Beira, forming an estuary. It is 250 kilometres (155 mi) long, with a drainage basin 31,000 square kilometres (12,000 sq mi) in size. Its mean annual discharge is 79 m³/s (2,790 cfs) at its mouth.

The Zambezi, on the other hand, is the fourth-longest 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 that of the Nile.
