Among the most awe-inspiring of waterfall types is the cataract waterfall.
A cataract waterfall occurs when a large amount of fast-moving water falls over a cliff. This type is categorized simply on sheer size and power.
Standing next to one can make you feel exceptionally small and fragile, and reminds viewers of the extraordinary strength of nature.
Famous among the world's cataract waterfalls are the Iguazo Falls on the border of Brazil and Argentina, pictured here. The waterfall is known for having one of the highest flow rates of any in the world. It even tops the famous Victoria Falls along the borders of Zambia and Zimbabwe.
In 2014, Iguazu Falls recorded an all-time high in its flow rate, carrying 46,300 cubic meters per second — 33 times the usual water flow rate — after torrential rains.
