Erica Gies' overarching message is that our attempts to control water may have worked in the short term, but are breaking down with time and climate change. So many of our waterways are straight, concrete, and race to the ocean too quickly. The natural way of water is to spread out, soak in, and slowly make its way across the land. Gies is a proponent of the Slow Water movement, which takes into account what water "wants" and tries to work with that. This includes fewer levees and more marshlands, more open floodplains and less infrastructure, and incorporates plants and animals that help the water stay on land as long as possible. This is crucial to refilling our aquifers, keeping saltwater from percolating inland, and losing so much of our coastline. There will have to be some surrenders, as the fight to hold on to property at the edges becomes too costly. But we have to remember that water will always win, and try to work with it rather than conquer it.
Gies's book looks at water projects across the globe - China, Vietnam, India, Peru, various spots in the United States, and more - to see what is making a difference. Some of the details about these various schemes were more than I wanted to absorb (I did some skimming). I am not an engineer by any stretch, but for those with more background knowledge, I think this book would be even more interesting.
