1

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

2

What causes an increase in kinetic energy

An increase in velocity or discharge

3

What are all channel processes dependant on

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

4

When does erosion occur

If there is excess energy after transportation of load

5

When does deposition occur

If energy is insufficient to move the load

6

Why does the river channel adjust in shape and size

To accommodate changes in the volume of water and sediment

7

How is potential/stored energy fixed

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