  • pothole | Infoplease

    Potholes are most commonly found at the bottoms of eddies in rivers and in plunge pools below cataracts; sometimes potholes in a rock outcrop indicate the former site of a rapid or cataract. Potholes are often found in formerly glaciated regions where whirling columns of glacial meltwater sank well-like holes, or moulins, through the ice.

  • Describe potholes and explain their formation? | Yahoo Answers

    Oct 27, 2010 · The formation of potholes occurs often in cold weather. Rain or waste water may flow onto roads and enter little cracks in the surface. If there is a cold spell of weather then the water will freeze, since ice occupies a greater volume than water, it will exert pressure on the road surface causing the road to bulge upwards.

  • 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.

    The process of formation is as follows; 1. As rivers near the sea they contain high sediment loads and the rivers start to spread out laterally. Ocean water entering these streams can reduce velocities as well. 2. This lateral movement of water reduces hydraulic radius and increases wetted perimeter. 3.

  • How Are Potholes Formed in Rivers? | Reference

    Potholes form at the bottom of rivers as eddies gouge out the bedrock of the river bottom. These eddies form as isolated whirlpools break off from the main current of the river. If the whirlpool pattern is persistent, it can dig permanent irregularities in the rock that form the initial conditions for further erosion of the pothole.

    Potholes are scattered all over the surface of Britain's road network, with every 1 in 6 roads in urgent need of resurfacing. It is well known that the chances of a pothole forming are largely increased during the winter months, and these potholes can form very quickly. There are multiple ways in which a pothole can appear on our roads, the most common ways shown below:

    Potholes form progressively from fatigue of the road surface which can lead to a precursor failure pattern known as crocodile (or alligator) cracking. Eventually, chunks of pavement between the fatigue cracks gradually work loose, and may then be plucked or forced out of the surface by continued wheel loads to create a pothole.
