- Solution: soluble materials dissolve in the water and are carried along.
- Saltation: pebble-sized particles are bounced along the river bed by the force of the water.
- Suspension: small particles like silt and clay are carried salong by the water
- Traction: large particles like boulders are pushed along the river bed by the force of the water

- Hydraulic action : The force of water that breaks rock particles away from the river channel.
- Erosion
- Attrition: Eroded rocks picked up by the river smash into each other and break into smaller fragments. Their edges also get rounded off as they rub together.
- Abrasion: Eroded rocks picked up by the river scrape and rub against the channel, wearing it away. Most erosion happens by abraision!
- Solution: river water dissolves some types of rock eg. chalk and limestone
- Erosion
