Floodplain

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 walls, and experience flooding during periods of high discharge. The soils usually consist of clays, silts, sands, and gravels deposited during floods.Because the regular flooding of floodplains can deposit nutrients and water, floodplains frequently have high soil-fertility, and this can encourage farming;

some important agricultural regions, such as the Mississippi river basin and the Nile, rely heavily on exploiting flood plains. Agricultural regions, as well as urban areas, have developed near or on floodplains to take advantage of the rich soil and freshwater. However, the risk of inundation has led to increasing efforts to control flooding.
