WebA meander is one of a series of regular sinuous curves in the channel of a river or other watercourse.

Part of the Encyclopedia of Earth Science book series (EESS) A meandering river valley that has cut down its bed into the bedrock, because of uplift or lowered base level, is called incised, intrenched, entrenched, inclosed or ingrown. It is characteristic of antecedent drainage systems. WebIncised meanders are meanders which are particularly well developed and occur when a river’s base level has fallen giving the river a large amount of vertical erosion power, allowing it to downcut.
