\nStatement I is false. Incised meanders are typically formed when a river that has already developed meanders on a floodplain (characteristic of the mature stage) experiences rejuvenation. Rejuvenation can be caused by processes like tectonic uplift of the land or a drop in the base level (e.g., sea level). This allows the river to cut downwards into its existing meandering channel, rather than eroding laterally across a floodplain. Statement II is true; incised meanders are specifically associated with the rejuvenation and uplift of the land, which increases the river’s erosive power.
\n<\/section>\n
\nRiver stages are often simplified into youthful, mature, and old. Meanders typically form in the mature stage on flatter terrain. Rejuvenation introduces a new cycle of erosion, causing vertical cutting even in a meandering course, leading to incised meanders.
\n<\/section>\n
\nIncised meanders can be either ‘entrenched’ (symmetrical valley sides, often due to rapid uplift or deep cutting) or ‘ingrown’ (asymmetrical valley sides, where some lateral erosion continues alongside vertical cutting). They are evidence of a change in the river’s energy regime after the initial meandering pattern was established.
