River rejuvenation

River rejuvenation refers to the process where a river's energy and course become more active or grow stronger after a period of decline. This typically occurs due to geological changes like uplift of the land or a reduction in sediment load, allowing the river to cut deeper into its bed and reshape its valley. Rejuvenation often leads to features like waterfalls, gorges, or terraces. It marks a new stage of erosion and landscape development, making the river more dynamic and capable of modifying its surroundings more aggressively.
