Over a period of yéars, the edges of this shelf will gradually bréak away and the waterfall will stéadily move upstréam.  Often, the rock strata just below the more resistant shelf will be of a softer type, and will erode out to form a shallow cave-like formation known as a rock shelter (also known as a rock house) under and behind the waterfall.

Stréams often become wider and more shallow just above waterfalls due to flowing over the rock shelf, and there is usually a deep pool just below the waterfall due to the kinetic energy of the water hitting the bottom.

Waterfalls are a hindrance to river transportation, and so the Welland Canal was built in 1829 to allow ships to pass Niagara Falls in the Great Lakes.
