Learn how mathematics and physics can reveal the hidden secrets of rivers, and insights into the deep relationships they have with landscapes, ecosystems and societies. Drawing on his recent Princeton University Press book, Where the River Flows: Scientific Reflections on Earth’s Waterways, Sean Fleming will look at topics like why rivers run where they do; how the same river can flood one year, yet dry up the next; how we forecast floods and water supplies; the impacts of climate change; and even whether rivers have “memories.” He also explores how science can help address the threats our watersheds face.
