River erosion is the process by which flowing water wears away the land along riverbanks and riverbeds. This occurs as the river's current moves sediment and rocks, gradually shaping the landscape. Over time, this can lead to the formation of features like meanders, oxbow lakes, and gorges. Factors such as water speed, volume, and the type of soil or rock influence the rate of erosion. Areas with softer materials erode more quickly than those with harder surfaces. Understanding river erosion is important for managing flood risks and maintaining healthy ecosystems along waterways.
