- Features of the middle course
- Wider
- Deeper
- Some Vertical erosion/lateral
- Hydraulic action
- Deposition more obvious
- Load size reduction
- Supension, transportation, saltation, traction
- Features of the lower course
- Wideest
- Deeepest
- Little erosion
- Less erosion
- Deposition fine material
- Load size is very small
- Transportation
- Saltation
- Sand sized particles may be bounced along the bed of river
- Traction
- Heaviest material is rolled along the river bed
- Suspension
- Small particles are carried within the water by turbulent flow
- Some minerals will dissolve in the water and be carried in solution
- Saltation
- Features of the upper course
