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.
By building levees up you are able to "funnel" more water down stream to a point that has not been built up! This will cause more water to over flow the river banks creating a worse flood condition!
Dikes are walls, or 'levees ' to stop rivers flooding.
Measures to control flooding include artifical levees, flood control dams, and placing limits on floodplain development.....:-)
flood barriers
levees are two parallel wall built at both sides of a river to prevent river overflowing
Negative effects are can cause flooding if broken
levees are used to prevent flooding of a river to the adjoing country-basically prevent flooding.

Dikes and levees prevent flooding by forming a barrier against rising waters.
