floodplain
Periodically inundated lowland
A floodplain is the flat land along a river that naturally floods when water levels rise.
Rivers deposit sediment here over time, creating fertile soil that attracts agriculture despite the flooding risk.
They built the house on the floodplain, so insurance was expensive.
Floodplains serve as natural overflow areas, and developing them increases flood damage downstream.
