International WaterFall Day – June 16, 2026

History of International WaterFall Day

A waterfall is usually defined as a point in a river where the water flows over a steep drop. As there are many types and methods used to classify waterfalls, what constitutes a waterfall continues to be debated. Despite being such an important part of human lives and history, waterfalls have not been very much researched, although Alexander von Humboldt did write about them in the 1820s. There is no name for the specific field of researching waterfalls but it is popular to describe studying waterfalls as ’waterfallology.’

European explorers used to document the waterfalls they came across. In 1493, Christopher Columbus wrote about Carbet Falls in Guadeloupe, which could be the first waterfall Europeans recorded seeing in the Americas. However, Geographer Brian J. Hudson suggests that it was uncommon to specifically name waterfalls until the 18th century.

This trend of, specifically, Europeans naming waterfalls is following people’s increased scientific focus on nature at the time, the rise of Romanticism, and the increased importance of hydropower due to the Industrial Revolution. However, European explorers would often ignore the names native peoples had originally given these waterfalls in favor of a more ’European’ name. For example, Scottish physician and explorer David Livingstone named Victoria Falls after Queen Victoria, even though it was already known as Mosi-oa-Tunya by the people native to the area.

Waterfall exploration continues to this day. Waterfalls are visited by people in droves mainly because they make great tourist sites; it is not just because they are beautiful, but also because they are relatively uncommon.
