Erosion in Rivers
- Hydraulic Power
- The force of the water on beds + banks of rivers
- Powerful when there is a flood
- It powers most of the types of erosion in rivers
- Corrasion/Abrasion
- Pebbles + boulders being carried along by the river
- It erodes the bed + bank away
- Corrosion
- Sometimes river water is slightly acidic and it can dissolve rocks over a period of time
- An example of this is the dissolving of limestone
- We get calcium hydrogen carbonate
- Attrition
- Pebbles banging into each other powered by hydraulic
power
- This causes the pebbles to eventually break
