In contrast to the upper reaches of a drainage basin where the rivers start, the middle reaches are characterised by more gentle relief, erosion and deposition processes and wider valley floors due to lateral erosion.
England is not a very nice place? How are meanders formed? A stream or river flowing through a wide valley or flat plain will tend to form a meandering stream course as it alternatively erodes and deposits sediments along its course.
This will commonly be things like shingle.
Formation of natural levees by spill-over of sediment during floods. In time the meander will migrate downstream as the river straightens.

Adjacent to the channel levee deposits build up, and gradually raise up the river over the floodplain mainly fine sediments. This part of the meander is deeper and the water flows faster here, the water also flows as helicoidal helical flow at this part of the meander, this is a corkscrew motion of the water.

A meander forms due to both deposition and erosion on either side of the river channel. How do meanders form? Describe one way that incised meanders form? This Site Might Help You. Get one-to-one help from a personally interviewed subject specialist.
This process can lead to formation of one of Geography's classic landforms, Ox bow lakes. This leads ot the formation of an ox-bow lake, becuase there is deposition at the neck of where the bedn was because this would have been the inside of the meander. Answered by Sam W.
The area over which they flood is known as the floodplain and this often coincides with regions where meanders form. Also when the river floods it leaves behind alluvium which is silt which makes the soils very fertile and good for plant grown, that is often why you see alot of agriculture near rivers.
When a meander gets cut off from the main stream body, an oxbow lake is formed. Rivers flood on a regular basis. Also a stream or river flowing through a wide valley or flat plain will tend to form a meandering stream course as it alternatively erodes and deposits sediments along its course.
