How floodplain is formed?
Floodplains are produced by lateral movement of a stream and by overbank deposition; therefore they are absent where downcutting is dominant. Any erosional widening of one bank is approximately equalled by deposition on the opposite side of the channel in the form of bar development along the inside of meander bends.
