Dayton, Kentucky depends on a levee system to prevent flooding by the Ohio River. From this overlook at Eden Park in Cincinnati, Ohio, we can clearly see in the left half of the image how much the city is protected. The inside channel of the meander (the Kentucky side) historically had a much lower slope created by the mechanics of stream flow. As stream flow congested and slowed on the inside channel, sediment dropped from the river that mounded into a point bar and usable land. However, periodic high river flows would inundate the whole point bar and the challenge became flood management. Dayton’s point bar was secured by this artificial levee system that is only so high. Our engineering of cities depends on knowledge of climate change.
