Why do incised meanders occur

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


When is an ingrown meander formed

When incision is slow and lateral erosion is occurring


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


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.


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.
