An oxbow lake is a U-shaped lake formed when a wide meander of a river Diagram illustrating the development of meanders in a. ![]() Please see the USGS social media sharing policy at. If you tag us with you are giving us permission to use your image. Here at USGS, we study how meanders are formed and can even model them to predict how the river may continue to change in the future, to better understand flooding hazards.Ĭan you find a meander in your area? If you don't see a river, see if you can spot a sidewalk or path that meanders, or watch how a drop of rainwater flows down a slightly sloped surface - does it make a straight or curvy path? Take a photo of a meander and tag us #findafeature or send it to us at be watching Instagram and Twitter for some great #findafeature examples and may share them here with the first name or initials of the contributor, and a general location. There are two different options for this task: An unlabelled version for students to copy and add their own labels to. This is because vertical erosion is replaced by a sideways form of erosion called LATERAL erosion, plus deposition within the floodplain. They are typical of the middle and lower course of a river. ![]() Meanders are the result of both erosional and depositional processes. In this activity, students recreate a diagram of a river meander as accurately as possible. A meander is a winding curve or bend in a river. Due to erosion on the outside of a bend and deposition on the inside, the shape of a meander changes over time. As part of their GCSE studies, students are expected to draw, label and annotate diagrams,maps, graphs, sketches and photographs. This is why you often see sand bars and beaches on the inside of the curve. Why is this? Water is pushed to the outside of a bend, and erodes the curve further, while water on the inside is slower and deposits sediment. Once a meander starts, it often becomes more and more exaggerated. 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. In antiquity, it was known as Maandros, and gave us the word meander to describe sinuous curves in a river or. A meander is when water flows in a curvy, bendy path, like a snake. This is the Byk Menderes, the longest river to flow into the Aegean.
