Pothole (landform) - Wikipedia

In Earth science, a pothole is a smooth, bowl-shaped or cylindrical hollow, generally deeper than wide, found carved into the rocky bed of a watercourse. Other names used for riverine potholes are pot, (stream) kettle, giant's kettle, evorsion, hollow, rock mill, churn hole, eddy mill, and kolk. Although somewhat related to a pothole in origin, a plunge pool (or plunge basin or waterfall lake ...

River Potholes: Modern and Ancient

Formed by water action A river pothole is a cylindrical, bowl-shaped, or irregular hollow that is usually deeper than wide. It is formed in the rocky bed of a stream by either the grinding action of sediment whirled around by stream eddies or the force of fast flowing water. Potholes usually have spirally

Pothole - Wikipedia

A pothole is a depression in a road surface, usually asphalt pavement, where traffic has removed broken pieces of the pavement.It is usually the result of water in the underlying soil structure and traffic passing over the affected area. Water first weakens the underlying soil; traffic then fatigues and breaks the poorly supported asphalt surface in the affected area.

Potholes - St Mary's Fluvial Studies

FORMATION OF POTHOLES!!! 1 Potholes form where a rock (or many rocks) is spun around in the same spot by circular eddy of water. The constant abrasion begins to wear away the bedrock into a hole. 2 Once started, the feature is self-reinforcing as the hole creates an even stronger eddy. 3 The rock being spun in the hole is called a grinder and ...

River Landforms - The British Geographer

Potholes form mainly in the upper course of the river, in high altitude where the river channel cuts directly into the bedrock. Potholes are the direct consequence of vertical erosion and processes of abrasion.The sequence of the development is quite easy to understand. As we know the river channel in the upper course is characterised by roughness, associated with large bedload.

Potholes. Holes carved into rock at the base of river with a whirlpool action. Water Fall's (Formation) Waterfalls are formed when a river flows from the hard rock onto the softer, less resistant rock. The less resistant rock erodes much more quickly and in a vertical manner. This causes a difference in height, and a waterfall is formed.

Rivers | Geography

Potholes These are circular depressions found on river beds. Potholes are formed by corrasion. Pebbles carried by the river are swirled around on the riverbed. This action erodes the rock on the riverbed forming potholes. Over time, they may widen and join with other potholes to form larger potholes, and the whole riverbed is deepened.
