Waterfalls Valley

A wwaterfall is an area where water flows over a vertical drop or a series of steep drops in the course of a stream or river.
  • Plunge: Water descends vertically, losing contact with the bedrock surface.
  • Horsetail: Descending water maintains some contact with bedrock.
  • Cataract: A large, powerful waterfall.
  • Multi-step: A series of waterfalls one after another of roughly the same size each with its own sunken plunge pool.
  • Block: Water descends from a relatively wide stream or river.
  • Cascade: Water descends a series of rock steps.
  • Segmented: Distinctly separate flows of water form as it descends.
  • Tiered: Water drops in a series of distinct steps or falls.
  • Punchbowl: Water descends in a constricted form and then spreads out in a wider pool.
  • Fan: Water spreads horizontally as it descends while remaining in contact with bedrock.
  • Ephemeral: They do not flow continuously.
A valley is a low area between hills or mountains typically with a river running through it.
  • River Valley: Formed by the erosive action of water flowing over the land.
  • Glacial Valley: Due to breadth and weight of glaciers, these valleys are wider and have flat bottoms with a contour similar to a "U"
  • Flat-floored Valley: Most common type of valley in the world. Over time rivers and streams spread across the valley (either River or Glacial), persistently eroding its edges.
