African Rivers: Most Reach the Coast, Some Are Endorheic

The vast majority of African rivers flow to the coast and empty into the ocean (Mediterranean, Atlantic, Indian Ocean). However, a few are endorheic (closed basins):

• Okavango River – spreads into the Okavango Delta (Botswana), evaporates.
• Chari/Logone Rivers – flow into Lake Chad (shrinking, no outlet).
• Ewaso Ng'iro – ends in Lorian Swamp (Kenya).

The Nile and Congo are the continent's largest exorheic rivers, reaching the Mediterranean and Atlantic respectively.
