distribution of water in Africa is closely linked to climatic conditions and terrain.Approximately half of the continent belongs to the areas of internal drainage.This is due mainly to the fact that the area receives very little rainfall.Those areas, which are characterized by their large volume, differ widely developed water network.Thus, the river on the continent of Africa are distributed very unevenly.
total annual flow of the continent is about 5390 cubic meters.According to this indicator gives Africa South America and Asia.In accordance with the pool area, the volume of wastewater, extension, many rivers in Africa are considered to be the largest in the world.
flow distribution, as well as the water network depends on various climatic factors, topography, rocks in the one or other region.Many rivers in Africa, before reaching the ocean, completed in the inland basins.Water network almost all over the continent have rain power.The exceptions are the rivers and other bodies of water and semi-deserts.In these areas, stocks are enriched by sewage.
serves as the watershed of the East African Plateau.Therefore almost the entire flow is sent into the Atlantic ocean.Rivers of Africa characterized by a large number of waterfalls and rapids, they are virtually useless for navigation.However, they have significant reserves of hydropower.
in Equatorial Belt, African rivers are flowing pretty all year round, forming a fairly dense river network.The subequatorial zones, they are full of water only during the rainy season.In dry tropical areas are practically no surface water.But these areas are common artesian basins.On the territory of the continent can be met and dry beds.They are filled with water after occasional rain.The rivers in the subtropical zone raising the water level is typical for the rainy season.While on the Mediterranean coast that happens in the winter.
biggest rivers on the continent - the Zambezi, Niger, Zaire (Congo).
latter is considered the most affluent of all.In addition, Congo ranks second on the continent after the length of the Nile.The length of Zaire - 4320 kilometers.Its swimming pool area and the volume is second only to the Amazon.Congo crosses the equator in two places and brimming throughout the year.It runs on the ledges in the highlands, in connection with which her many waterfalls and rapids.The largest tributaries are: Kasai, Ubangi, lukuga river.Congo empties into the Atlantic Ocean.
The longest river on the continent is considered to be the Nile.In addition, it has the largest length in the world.The length of the Nile River - 6671 kilometers.The swimming pool area is 2.87 million square kilometers.In the upper reaches of the Nile rushes down the canyons.It produces a lot of waterfalls and rapids.On flat terrain for quite calm and slow;in the area called the White Nile River.With the Ethiopian highlands runs the largest right tributary.The city of Khartoum, White Nile and Blue Nile tributary merge.The bed becomes twice as wide.
Neal crosses the Sahara desert without tributaries here.Falling into the Mediterranean Sea forms a delta.
The largest river flowing into the Indian Ocean, Africa, the Zambezi is considered.Its length is 2660 kilometers.Victoria Falls, one of the largest in the world, is located on the river.It has a width of one thousand eight hundred and height - one hundred and twenty meters.
the third largest on the continent is considered to be the Niger River.The top and bottom line, it features a large number of waterfalls and rapids.On average, during the Niger - the river flat.A large part of its course crosses enough drylands.
