HGS RESEARCH HIGHLIGHT – Source Water Protection in Quebec City: Using an integrated 3D hydrological model to investigate surface water-groundwater interactions

The research, presented as a poster by Benjamin Frot at EGU 2025, explores the use of HydroGeoSphere (HGS) to investigate surface water–groundwater interactions in the Saint-Charles River watershed, which supplies drinking water to Quebec City. With a focus on source water protection, the study addresses the challenges posed by increasing urbanization, contamination from septic systems and road salts, and reduced water availability during low-flow periods. The work is part of a larger project aimed at evaluating the vulnerability of Quebec City's main surface water intake.
