Levees are natural embankments which are formed when a river floods. When a river floods friction with the floodplain leads to a rapid decrease in the velocity of the river and therefore its capacity to transport material. High pressure, caused by a river meeting its bank-full capacity, can cause a levee to burst.

Is a levee the same as a dyke?

Levees protect land that is normally dry but that may be flooded when rain or melting snow raises the water level in a body of water, such as a river. Dikes protect land that would naturally be underwater most of the time.
