Embankments – Raised banks along the river; they effectively make the river deeper so it can hold more water
They are expensive and do not look natural but they do protect the land around them.
Difference between embankments and levees:
- An embankment can hold water and often supports a road or railroad.
- A levee is usually only used to prevent flooding.
The "M" on the bank is meant (embankment) to protect the land by holding more water.
