For a transcript, please visit https://climatebreak.org/using-paleo-valleys-to-recharge-aquifers-with-dr-rosemary-knight/ How can insights from geophysics help us to make better use of rainwater? Geophysicists, like Stanford’s Dr. Rosemary Knight, can identify ancient, buried riverbeds called paleo valleys. We spoke with her about how such geologic structures can help us recharge aquifers deep below the Earth’s surface.
