GeographyRivers
Quick Answer
A floodplain is the flat land beside a river that is periodically flooded when the river overflows its banks.
The Full Story
Floodplains are built by repeated deposition of silt, sand, and clay during floods. Because these areas receive fresh sediment, they are often fertile and have supported farming and settlement for thousands of years. Many major civilizations developed on floodplains, including those of the Nile, Tigris-Euphrates, and Indus rivers. At the same time, floodplains are naturally hazardous places to build because they can be inundated quickly during heavy rain or snowmelt.
