WebMeandering rivers will move/migrate towards the eroding bank, and therefore will have a more uniform shape, rather than braided rivers, which can migrate in many directions. Meandering rivers also contain abundant suspended sediment, leading to the formation of oxbow lakes, which are not found near braided rivers. Summary WebJan 25, 2024 · Abstract.
