WebA meander is when water flows in a curvy, bendy path, like a snake. As a river makes its way through an area that is relatively flat, it often develops bends as it erodes its way through the path of least resistance. Once a meander starts, it often becomes more and more exaggerated. Why is this? WebFeb 6, 2024 · The phase lag shows a relatively low variability for the same river segment but varies between 2.1× and 4.7× the average channel width across different rivers. Virtually all bends show a downstream shift of the maximum migration rate relative to the bend apex.
WebMeanders are formed in the middle course of a river. As the river gains more velocity, the water is pushed to the outside of the river causing more erosion on the outside bend, which forms a steep river cliff. This is achieved through …
