## Definition

an area of land next to a river that is often flooded when the water level rises. This land is usually flat and very good for farming.

For teachers: an area of land adjacent to a river or stream that is susceptible to flooding during periods of high discharge. Often characterized by fertile soil due to the deposition of silt during inundation.

## Examples

- The farmer lives on a floodplain near the river.
- Many ancient civilizations, such as the Egyptians, settled on floodplains because the soil was so rich for growing crops.
- While the floodplain provides highly productive agricultural land, modern urban development in these zones often requires significant investment in levees and drainage systems to mitigate seasonal flood risks.
