River meanders. Aerial view of a meandering river & ox-bow lakes. A meander occurs when there is a slight bend in the river. The water flowing on the outside of the bend flows faster than the water on the inside. The faster water will erode the river bank more quickly whilst the slower water will deposit sediment that it is carrying. The meanders increase in size until there are only narrow necks of land between them as seen here. Eventually the river cuts through the neck and the meander is left isolated from the river's flow. It is then known as an ox-bow lake because its curved shape looks like the horns of an ox. Photographed at North Slope in Alaska,USA | |
