What do levees look like?

Levees are usually large earthen or concrete structures built along riverbanks or Coastlines, designed to prevent flooding. They often appear as raised embankments or walls, sometimes with a gentle slope on the land side and a steeper side facing the water. Many levees are covered in grass or vegetation to help with erosion control, while some may have access roads or walkways on top for maintenance and observation. Their height and design can vary significantly depending on the location and specific flood risk they are meant to mitigate.
