Natural Levees : When a river is over flooded, its water crosses its banks. At that time, the speed of the water is reduced, and the pebbles and stones carried by the river get deposited near the banks.

Natural Levee |
On account of frequent floods, the area where these sediments are deposited near the bank of the river rises higher than the flood plain.
This high wall is called a natural levee or natural embankment. Such levees are found on the banks of the Mississippi, the Huang - ho etc., Southern bank of river Ganga (India).
