What characterizes the outside of a meander bend?

The outside of a meander bend is characterized by faster-moving water, which leads to increased erosion of the riverbank. This dynamic occurs due to the shape of the meander; as the water flows around the curve, it moves more rapidly on the outer edge compared to the inner edge, where the water is slower. The erosion on the outside bank can lead to the undercutting of the bank, making it steeper and contributing to the overall shaping of the river's course. This process is crucial in the development of river landscapes, affecting sediment transport and the overall morphology of river systems.

In contrast, the inner bank of the meander, where the water flows more slowly, tends to accumulate sediments, which is why the outer bend is recognized specifically for its erosion rather than deposition or features such as flat profiles or vegetation. These factors highlight the importance of flow velocity in river dynamics and how it influences the landscape.
