Levees and flood plains

  • Levees and flood plains are formed when the level of the river is above the level of the land.
  • Levees are banks on the side of the river which prevent the river flooding into the flood plain.
  • Levees can be man made - concrete or artificial - mud.
  • The flood plain is made up often of fertile land which encourages villages but then these can be at risk.
  • When the river is full, it floods into the flood plain and leaves behind fertile soil.
