- they may become saturated for only a short period of time;
- their alignment is dictated by flood protection requirements;
- borrow is generally obtained from channels excavated adjacent to the levee.

Why are levees built?
Similar to dikes, levees are constructed to control the flow of ocean waves or prevent riverbanks from spilling over. They’re usually man-made within the earth and created to divert, contain, or control the flow of water and decrease flood risk.
Why are levees important?
