Meander identification and geology
A sinuous, looping curve in the course of a river, formed by the lateral erosion of the outer bank cut bank and deposition on the inner bank point bar of each bend. Meandering is characteristic of rivers with moderate gradient and fine-grained cohesive banks. Over time, meanders migrate laterally and downstream, eventually forming cutoffs that produce oxbow lakes. Field: geomorphology. Example: The lower Mississippi River is famous for its large-scale meanders, which migrate laterally at rates of up to 20 m per year and have been repeatedly cut off to form oxbow lakes across the floodplain.. Related terms: Fluvial, Oxbow lake, Point bar, Cut bank.
