The meanders that form part of either an entrenched river or meander valley are most commonly known as incised meanders.[1] They are commonly classified as either an ingrown meander or an entrenched meander. For a long time, it was argued that ingrown meander occurs when downcutting process is slow and the river can cause lateral erosion, leading to an asymmetric valley. In addition, it was also argued for a long time that an entrenched meander forms when there is a rapid incision of the river bed such that the river does not have the opportunity to erode the lateral side.
