The top 3 largest waterfalls in the world refer to Iguassu Falls which is at the junction of Brazil and Argentina, Victoria Falls which is at the junction of eastern Zambia and Zimbabwe as well as Niagara Falls which is at the junction of United States and Canada. The three falls in terms of width, size, flow rate far exceeds that of other waterfalls, and all of them are transnational waterfalls.
TOP 1. IGUAZU FALLS (IGUASSU FALLS)
[Puerto Iguazú, Argentina / Foz do Iguaçu, Brazil]
Height is 64-82 meters. Width is 2,700 meters. Annual average flow rate is 1,746 cubic meters per second.
Iguazu Falls (or more accurately Iguazú Falls) is the Spanish name (Argentina) for this mammoth waterfall. You might also see it referred to as Iguassu Falls or Iguaçu Falls if you favor the portugese name (Brazil).
Moreover, you might also see it referred to as Yguazú Falls, which I believe is native Guaraní. In fact, the meaning of the name (originally Guaraní) is said to roughly translate to “big water.” The photo you see at the top of this page certainly attests to its grand nature.
With its brink spanning a distance of an incredible 2km in its average flow of 1000 cubic meters per second, this falls tops our list of favorites. The falls actually consists of some 275 individual waterfalls and cascades.
But no matter how you spell or say its name, we have to say that it is indeed a crazy waterfall.
How crazy, you might ask?
Consider a network of 275 different waterfalls spanning an area 3km wide (2km of which is the upper rim of the waterfall) during its normal flow of around 1000 cubic meters per second. It is such a natural wonder that UNESCO designated the falls as a World Heritage Area in 1986.
