    Research Technique: Modelling




Our research characterizes watershed processes through innovative techniques in GIS, remote sensing and modelling. We conduct science that tracks the movement and fate of nutrients within and through watersheds, which are released to the atmosphere and aquatic systems.

We work with a global network of scientists focused on discovering watershed responses to global change and extending watershed research into more broad and integrative disciplines like ecosystem health and ecosystem services.
