Please Note: in response to the emerging COVID-19 pandemic, the HESSS5 conference has been postponed until further notice. We will communicate an update with the new dates when appropriate.

General Information

Welcome to HESSS5, the 5th International Conference on Hydrology and Earth System Science for Society. HESSS5 is hosted by the Global Institute for Water Security at the University of Saskatchewan, and will be held during Saskatoon Water Week 2020 at the Delta Bessborough Hotel, from June 15-19, 2020. HESSS5 will provide a forum for a diverse mix of researchers, students, government officials, stakeholders, practitioners and private sector participants to engage in transdisciplinary discussions on research progress, emerging research needs and socio-economic and political innovations that are necessary to ensure regional and global water and food security. Crosscutting themes will include governance, resilience, and progress towards UN Sustainable Development Goals. Some sessions will also be open to the public and will include public lectures.

Participants from all disciplines are welcome, but will primarily come from the hydrological and agricultural communities, with interests in integrated/intersectoral models, land surface models, remote sensing, socio-economic and policy innovations, climate adaptation and surface and groundwater management.

Sessions and abstracts are encouraged on a wide range of related topics, included but not limited to: integrated hydrological modeling, agricultural crop modeling, land surface modeling including agriculture and groundwater, remote sensing of hydrology and agriculture, groundwater sustainability, climate change impacts on water and food security, climate adaptation strategies for urban and agricultural regions, and socio-hydrology including innovations in integrated river basin planning and management and conjunctive surface and groundwater management.

Since 2007, the Hydrology Delivers Earth System Science to Society (HESSS) international conferences have provided forums for strengthening synergies between the hydrologic and related communities and the public. HESSS1, held in Tsukuba, Japan in 2007, bridged the gap between hydrometeorology and social demands for improved prediction. HESSS2, held at the University of Tokyo in 2009, brought the global modeling and flux measurement communities together. HESSS3 was held at Seoul National University in 2013 and focused on sustainable ecological and societal systems. HESSS4, held at the University of Tokyo in 2017, brought the GEWEX and model intercomparison communities together with the remote sensing and data assimilation communities, with a view towards communicating science to society.
