Introduction of Waterfall

A waterfall is a place where flowing water rapidly drops in elevation as it flows over a steep region or a cliff.

Types of waterfalls

Block: Water descends from a relatively wide stream or river.

Cascade: Water descends a series of rock steps.

Cataract: A large, powerful waterfall.

Chute: A large quantity of water forced through a narrow, vertical passage.

Fan: Water spreads horizontally as it descends while remaining in contact with bedrock.

Frozen: Any waterfall which has some element of ice.

Horsetail: Descending water maintains some contact with bedrock.

Plunge: Water descends vertically, losing contact with the bedrock surface.

Punchbowl: Water descends in a constricted form and then spreads out in a wider pool.

Segmented: Distinctly separate flows of water form as it descends.

Tiered: Water drops in a series of distinct steps or falls.

Multi-step: A series of waterfalls one after another of roughly the same size each with its own sunken plunge pool.
