AI overview
A floodplain is an area of land adjacent to a river that becomes inundated when the river overflows during floods. Floodplains are formed by the natural processes of rivers depositing sediment and meandering across their surrounding landscape over time.

A floodplain or flood plain or bottomlands is an area of land adjacent to a river. Floodplains stretch from the banks of a river channel to the base of the enclosing valley, and experience flooding during periods of high discharge. The soils usually consist of clays, silts, sands, and gravels deposited during floods.
