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.

  2. Aug. 16, 2021New paper proposes framework for rescuing historical climate data

    A short paper entitled “Rescuing Historical Climate Observations to Support Hydrological Research: A Case Study of Solar Radiation Data”, presented at the ACM Symposium on Document Engineering 2021 (DocEng ’21), outlines research for establishing an efficient and accurate process of digitizing paper-based climate data. The framework for this work was set up by evaluating the performance of two optical character recognition (OCR) engines, namely Tesseract OCR and ABBYY FineReader.

  3. Aug. 13, 2021One Health International Summer School organized by University of Bern

    The 2021 Virtual One Health International PhD and Postdoc Summer School on “Environmental Pollution: From soils to human health” focussed on the fate, transport and health effects of contaminants in the environment. The program ran from Monday August 9 to Friday August 13. It included 10 keynote lectures given by leading national and international scientists, providing participants with detailed overviews of the key issues concerning environmental pollutions and their connections to global health.
