Being situated in Africa’s largest rainfall belt it discharges a large 34 000 cubic meters of water a second into the Atlantic ocean, second solely when it comes to water circulation to the Amazon.
It has the most important catchment basin in Africa masking 4.1 million sq. km, and due to a few of its canyons, is the deepest river on the planet. The supply is taken into account to be the Chembeshi River in Northern Zambia not so removed from the supply of the eastward flowing Zambezi River.
