My research focuses on tracking water through the Critical Zone. Using a combination of naturally occurring radioactive and stable isotopes, I hope to identify the sources, pathways and residence times of water leaving the catchment as either streamflow or evapotranspiration. The goal is to estimate the total water storage volume in the soil and weathered bedrock, and to gain insight in the plant water strategies under drought stress and normal condition. Future research will include integrating this new knowledge into a fully-coupled surface-subsurface numerical model (ParFlow) of the Providence Creek catchment.
