People change the way water moves around them in many different ways. Reclaiming land from rising ocean tides requires levees and seawalls, but few of us know how these amazing engineering tasks are actually carried out. This exciting title takes a look at famous levees on rivers and seawalls on oceans around the world, including the series of projects protecting New Orleans, Louisiana. It also explores what happens when these projects fail, and how engineers today are working to make better levees to battle the growing threat of climate change and rising water levels around the globe.
