The term Levee is one of many used in low lying lands around the world where protection from sea/river flooding is paramount.
For example in Holland they are called 'Polder dykes'
A dike (or dyke) is an artificial earthen wall, constructed as a defense or as a boundary. It is also known in American English as a levee.

Levees are raised banks beside a river to help stop it bursting its banks when in flood. They are used in and around New Orleans in the US for example, and it was because the levees failed and broke that hurricane Katrina flooded the city to such devastating effect.

Wikipedia has all the information you will need to know about how levees coupled with water pumps hold back water to make low lying land available for building on http://en.wikipedia.org/wiki/Levee

They are used to protect land from floods form any body of water like river and oceans. Unlike a dam which uses it to control flow of rivers, retain good water for our water supply system, and for making electricity power to bring power to millions of homes, and other buildings. Good luck on your geography homework.
