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.

  3. June 7, 2021Canadian Peatland Carbon Emission Paper by Arash, Fereidoun and Philippe Published in Nature

    A study by ecohydrology members Arash Rafat, Fereidoun Rezanezhad and Philippe Van Cappellen was published in Nature’s Communications Earth & Environment journal! This study explores how carbon emissons of Candaian Peatlands are projected to increase by 103% by 2100. The news has also been published by the UW press and Water Insitute News.
