Geomorphic processes
Fluvial
Erosion
Where erosion takes place
Most erosion takes place in the upper catchment (upper course).
Most of the erosion happens when the river has high discharge and velocity.
Sediment can also move through mass movement and weathering processes.
Types of erosion
Hydraulic action
Attrition
Abrasion
Solution
Transport
Traction -- big rocks
Saltration -- medium rocks
Suspension -- small rocks
Solution -- dissolved materials
Deposition
Occurs when the river losses energy
Reasons for loss of energy
River flowing into a static (unmoving) sea can reduce velocity.
Tides and currents can be moving in different direction.
Processes caused by water
Aeolian
These are processes caused by wind.
Wave processes
Weathering
Mass movement
