Incised Meanders (Rejuvenation) Flashcards
1
Q
Why do incised meanders occur
A
As a result of the rate at which vertical erosion is occurring.
2
Q
When is an ingrown meander formed
A
When incision is slow and lateral erosion is occurring
3
Q
What does an incised meander look like
A
The valley becomes asymmetrical, with steep cliffs on the outer bends and more gentle slip-off slopes on the inner bends
4
Q
What are entrenched meanders
A
With rapid incision, when downcutting or vertical erosion dominates, the valley is lore symmetrical, with steep sides and a gorge like appearance.
5
Q
When do incised meanders occur
A
If a rejuvenated river occupies a valley with well developed meanders, renewed energy results in them being incised or deepened.
