A flood plain of sedimentary deposit forms where streams a stream overflows in the lowlands.
An region of land adjacent to a river that stretches from the banks of its channel to the base of the surrounding valley walls and that floods at times of heavy discharge is known as a floodplain, or bottomlands. Usually, clays, silts, sands, and gravels that were deposited during floods make up the soils.
