Ecohydrology at the University of Waterloo

Water is our most precious natural resource. The availability and quality of fresh water not only impact human health and wellbeing, but also the functioning of essential ecosystems, including rivers, wetlands, lakes and coastal ecosystems.

Most available fresh water is present as groundwater. Exchanges between groundwater and surface water occur throughout the landscape and support a plethora of key ecosystem services. The multidisciplinary research program in ecohydrology is dedicated to advancing the understanding of the fluxes and transformations of nutrient elements (especially P, N, Si) and metals at the groundwater-surface water interface, and assessing their consequences for the health and functioning of aquatic ecosystems.

Our research team includes biogeochemists, hydrologists, ecologists, environmental chemists and microbiologists, who combine laboratory experiments, field sampling and mathematical modelling.

  1. Dec. 10 to 14, 2018AGU Fall Meeting 2018

    American Gephysical Union (AGU) Fall Meeting 2018 is taking place in Washington, DC

  2. Dec. 18, 2018Earth Science Department Seminar

    Microbe-mineral-fluid interactions: Case studies from natural environments, industrial problems and arctic biogeochemical processes 

    Presented by Dr. Jenine McCutcheon, School of Earth and Environment, University of Leeds

    Abstract: Microbial processes influence geochemical reaction pathways in a range of natural and engineered environments. These processes often result in the precipitation, alteration, or dissolution of mineral phases, thereby also altering the chemistry of the surrounding fluid.
