They increase the flooding because leaves are meant to hold water back. For example think of the Hoover Dam which is almost like a levy. Behind it is a huge lake. If the dam wasn't there the water would be no where near the height that it's currently at. If the Hoover Dam broke it would cause flooding for hundreds of miles. This is why levees increase the destruction caused by flooding. There is more water then what there would be if the levee wasn't there..
