Compartmentalization of the Terrestrial Water Cycle
by Dr. Jeffrey McDonnell
Global Institute for Water Security, University of Saskatchewan
The catchment annual water balance (i.e., input minus output equals change in storage) is the most important equation in hydrology. But recent studies using stable isotope tracers show a much more complex terrestrial water cycle than simple hydrometric observations suggest. At scales from global to microscopic, the water cycle appears highly compartmentalized and poorly mixed at timescales well beyond the annual measurements of input and output. This presentation summarizes recent work and attempts to describe how this stored inventory of old water links to streamflow and transpiration outputs.
Dr. McDonnell is a respected hydrologist and has authored approximately 300 papers. In recognition of his work, he has received the 2016 International Hydrology Prize from the International Association of Hydrological, UNESCO and the World Meteorological Organization, the Dalton Medal from the European Geophysical Union, the Birdsall-Dreiss Distinguished Lecturer Award from the Geological Society of America, and the Gordon Warwick Medal from the British Society for Geomorphology.
