Groundwater - Stream Water Interactions
Groundwater sustains stream baseflow through periods of no precipitation. Groundwater plays a critical role in watershed hydrologic, thermal and chemical budgets. We use and develop environmental tracer techniques to quantify where, when and how much groundwater discharges into streams. We seek to use the stream as an integrated signal to identify the amount, age distribution and source of groundwater discharging to streams big and small from the alpine to the tropics.
