What job do levees perform?

Levees are embankments built along rivers or Coastlines to control and manage water flow, primarily to prevent flooding in adjacent areas. They act as barriers that protect land, infrastructure, and communities from rising water levels during storms or heavy rainfall. By containing or redirecting floodwaters, levees help maintain agricultural productivity and safeguard property. However, they can also create a false sense of security, potentially leading to increased development in flood-prone areas.
