How is kinetic energy determined

By the volume of flowing water (discharge), the slope or channel gradient down which it is flowing and its average velocity


What causes an increase in kinetic energy

An increase in velocity or discharge


What are all channel processes dependant on

The amount of energy available (this is a delicate balance)


When does erosion occur

If there is excess energy after transportation of load


When does deposition occur

If energy is insufficient to move the load


Why does the river channel adjust in shape and size

To accommodate changes in the volume of water and sediment


How is potential/stored energy fixed

By the altitude of the source of the stream in relation to base level
