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.

How can building up natural levees cause flooding worse downstream?
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!
What are levees used for and how do they help protect communities from flooding?
Levees are structures built along rivers or coastlines to prevent flooding by containing the water within a designated area. They help protect communities by reducing the risk of water overflowing and causing damage to homes, businesses, and infrastructure.
What do people sometimes use to build artificial levees to prevent searious flooding?
People often use materials like sandbags, concrete, and steel sheet piling to build artificial levees to prevent serious flooding. These materials are chosen for their ability to withstand pressure from rising water and provide a barrier to reduce the risk of flooding in areas prone to inundation.
How do levees cause erosion on Louisiana's coast?
Man-made levees can fail in a number of ways. The most frequent form of levee failure is a breach. A levee breach is when part of the levee actually breaks away, leaving a large opening for water to flood the land protected by the levee.
How does very wet soil cause floods?
Very wet soil can contribute to floods when it reaches its saturation point and is unable to absorb any more water. This excess water then runs off the soil surface and accumulates in rivers and streams, leading to an increase in water levels and potential flooding. Additionally, saturated soil can weaken structures such as levees and embankments, further exacerbating the risk of flooding.
What are positive and negative effects of levees?
