1

Why do incised meanders occur

As a result of the rate at which vertical erosion is occurring.

2

When is an ingrown meander formed

When incision is slow and lateral erosion is occurring

3

What does an incised meander look like

The valley becomes asymmetrical, with steep cliffs on the outer bends and more gentle slip-off slopes on the inner bends

4

What are entrenched meanders

With rapid incision, when downcutting or vertical erosion dominates, the valley is lore symmetrical, with steep sides and a gorge like appearance.

5

When do incised meanders occur

If a rejuvenated river occupies a valley with well developed meanders, renewed energy results in them being incised or deepened.
