This list covers 22 rivers with names running from “Zambezi” to “Zwarte Water.” They range from major waterways that cross whole continents to short streams that barely stretch beyond a single town. Some carry cargo and hydroelectric power, while others mainly support farming, irrigation, or drinking water for the towns along their banks.
Rivers are natural channels of flowing water that shape the land they pass through, carving valleys and feeding the lakes and seas they reach. Many have supported human settlements for thousands of years, and the Zambezi’s Victoria Falls remains one of the most famous natural landmarks tied to any river on this list.
