Difference between a plunge pool and a pothole

Difference between a plunge pool and a pothole

Here’s a tabular comparison between a plunge pool and a pothole:

AspectPlunge PoolPothole
FormationCreated by the erosive action of waterfalls or cascading waterFormed by the swirling action of fast-flowing water in river channels
LocationLocated at the base of waterfalls or rapidsTypically found along riverbeds or in rocky stream channels
SizeCan vary in size, ranging from small basins to larger poolsRelatively smaller in size, often resembling cylindrical holes
DepthCan be relatively deep, depending on the erosional processGenerally shallower in depth compared to plunge pools
ShapeTypically has a basin-like shape with a concave or circular formOften has a cylindrical or irregular shape
Water FlowReceives the force of falling or cascading water from aboveExperiences the turbulent flow of water along the river channel
ErosionCreates a deep depression through the erosive force of waterForms through hydraulic action and abrasion by sediment particles
Geomorphological ImpactCan contribute to the formation of canyons or gorgesMay create distinctive depressions or pothole landscapes
ExamplesFairy Pools in Scotland; Niagara Falls plunge poolsGlen Potholes in Scotland; Boulder Potholes in the United States

It’s important to note that both plunge pools and potholes are features formed by the erosive action of water, but their distinct locations and formation processes result in some differences.
