How are levees formed

Levees are formed by the repeated flooding of a river which helps a levee form and the river must be carrying a large load. Also as a river floods it loses power, speed and velocity so it is able to drop sediments. The larger sediments are deposited closer to the channel and great thickness of alluvium can build up. Levees are also formed as the natural embankments at the side build up.
