Lower Stage Flashcards
What is the gradient like in the lower stage
Flatter
What do meanders create in the lower stage
Create a wide flat floor with floodplains and levees
What are 2 key things in the lower stage and what are they caused by
Floodplains and levee
And they are caused by deposition
Floodplain
Land on either of a river in the lower stage that is likely to flood when a river breaks its banka
What makes the valley wide and flat
The meander eroding laterally
Levees
Banks that form when rivers flood
What causes levees

Levees create a new
River level
