Areas of Study
The McDonnell lab focuses on measuring, modeling and understanding watershed-scale water cycling.
Previous work in the group has focused on streamflow generation and the age, origin and pathway of storm runoff.
The group is now broadening its aims and going after questions of how geology and biology affect the amount and age of water in streams and how isotope tracers can help answer these questions.
Our long term goal is the development of an age-based theory of how water is stored and released in watersheds to complement and extend the traditional water balance.
