Incised river
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. There are two types of incised meanders, entrenched meanders, and ingrown meanders. Incised Meanders form during the youth phase of the river. WebThe incised river is a vertically-contained stream that has abandoned previous floodplains due to a lowering of local base level and is characterized by high streambanks bounded by alluvial terraces. Incised rivers, however, can also be located in certain landforms and valley types that are naturally associated with entrenched rivers.

River incision is the natural process by which a river cuts downward into its bed, deepening the active channel. Though it is a natural process, it can be accelerated rapidly by human factors including land use changes such as timber harvest, mining, agriculture, and road and dam construction. See more River incision is the narrow erosion caused by a river or stream that is far from its base level. River incision is common after tectonic uplift of the landscape.
