Natural levees are depositional landforms on either side of the banks of a river. What
are the disadvantages of natural levees.
1) Levees if breached can cause catastrophic floods.
2) Levee forming regions cannot be used for agricultural purposes.
3) Levee formation leads to sedimentation of river basins.
Choose the correct disadvantage/s from the following codes.
Explanation:
Levee forming regions are good for agricultural purposes as its soil is renewed every year
thus imparting fertility.
As the levee limits the flow of river water within its boundaries the river sheds its sediments
only in the river basin thus making river basins narrower and shallow thus increasing the
risks of floods.
