How do levees actually cause flooding?
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.
