Levees have been used for thousands of years, with some of the earliest recorded examples dating back to ancient Egypt around 3000 BCE, where they were constructed to manage the Nile River's flooding. In the United States, significant levee construction began in the 18th century, particularly in the Mississippi River Valley, to protect agricultural lands from seasonal flooding. Over time, levees have evolved in design and materials, becoming crucial components of flood management systems worldwide.

Why were levees built?
Levees were built primarily to control river flooding and protect adjacent land, communities, and infrastructure from inundation. By elevating the riverbanks, levees help to direct and contain water flow during heavy rainfall or snowmelt, reducing the risk of catastrophic flood events.
