List of waterfalls by flow rate

From Wikipedia, the free encyclopedia

This list of waterfalls by flow rate includes all waterfalls which are known to have an average flow rate or discharge of at least 150 cubic metres per second (5,300 cu ft/s). The waterfalls in this list are those for which there is verifiable information, and the list should not be assumed to be a complete list of waterfalls which would otherwise qualify as globally significant based on this metric.

Although the river initially still fell over 100 m (330 ft) into the sinkhole, very rapid headward erosion has since left no significant waterfall at this location.[80][81][82]
