You know when you go Bowling, you can get bumpers put up in your lane to keep the ball from going in the gutter? A levee is basically the same thing, although on a much larger scale. Generally they're piles upon piles of dirt that are put along the side of a river to keep the water from going over the sides and flooding whatever is next to it. Hope this answered your question! (:

Levees are raised embankments constructed along riverbanks to prevent flooding. They act as barriers to hold back floodwaters and protect nearby land and communities. Building levees is a common way to manage flood risks in flood-prone areas.
When levees are built along a section of the river, the water will rise higher, then the water will flood in a different place that did not flood before the levee was built. Many natural flood plains have been cut off by levees. That is why cities flood more because the high water is going to go somewhere. Levees don't stop high water. They just cause it to move somewhere else.
