A Taxonomy of Waterfall Types
Waterfall classification is more useful than aesthetic. The form of a fall reveals its geology and erosion stage; knowing the type helps you read the landscape. This guide covers the nine basic types defined by the World Waterfall Database.
Plunge
Water leaves the lip cleanly, falling free until impact. Caused by a hard caprock over softer rock below. Example: Yosemite Upper Falls (436 m). Photographically: the most dramatic type.
Horsetail
Water stays in contact with the rock as it falls — typically narrow and tall. Example: Bridalveil Fall, Yosemite (189 m). Softer photographic feel than a plunge.
Fan
Water spreads wider as it descends, fan-shaped. Example: Tvindefossen, Norway (152 m, spreading to 60 m wide at base). Photographically: emphasises the width.
Cascade
Water flows continuously down a steep but irregular rock face, without distinct lips. Example: Cascata del Toce, Italy. Often combined with shorter steps and slides.
Cataract
Large-volume waterfall (in width and flow), regardless of height. Example: Iguazú's Garganta del Diablo. Cataracts emphasise power; height is secondary.
Block
Wide rather than tall — width exceeds height. Example: Niagara's Horseshoe Falls (57 m tall, 670 m wide). The classic 'curtain'.
Tiered
Multiple discrete steps separated by pools or short flat reaches. Example: Sutherland Falls (three steps, 580 m). Often photographed as a single tall column.
Segmented
The flow splits into multiple parallel streams before or during the fall. Example: Seven Sisters, Geirangerfjord — seven separate falls. Photographically: complex, abstract.
Punchbowl
Water plunges through a narrow vertical hole into a wide pool below. Example: Punchbowl Falls, Oregon. Distinctive 'spurt' shape from above.
