HydroSphereAI Featured in Water Canada’s January/February 2026 Magazine
We’re excited to share that HydroSphereAI (HSAI) is featured in the January/February 2026 issue of Water Canada, highlighting how machine learning is helping close critical gaps in streamflow forecasting across Canada.
HGS RESEARCH HIGHLIGHT - Natural and anthropogenic drivers of the water table dynamics in a riparian fen peatland
This publication, co-authored by Adrien Renaud, Claude Mügler, Véronique Durand, and Marc Pessel, which examines the natural and anthropogenic drivers of water table dynamics in a riparian fen peatland along the Essonne River in France. This study leverages HydroGeoSphere (HGS) to couple surface and subsurface hydrology, providing new insights into how precipitation seasonality, vegetation activity, and river regulation influence peatland water levels.
HGS RESEARCH HIGHLIGHT - Using water sources extent during inundation as a reliable predictor for vegetation zonation in a natural wetland floodplain
We’re pleased to highlight this publication, co-authored by Tomasz Berezowski and Martin Wassen, which investigates how the extent of water sources during inundation can be used as reliable predictors of vegetation zonation in wetland floodplains. This study leverages HydroGeoSphere (HGS) together with the Hydraulic Mixing-Cell (HMC) method to address long-standing challenges in modelling vegetation dynamics by explicitly accounting for the spatial distribution of different water sources during floods.
HGS RESEARCH HIGHLIGHT – External and internal drivers behind the formation, vegetation succession, and carbon balance of a subarctic fen margin
In this research publication, researchers investigated the formation, vegetation succession, and carbon balance of peatland margins in Finnish Lapland. This study leverages HydroGeoSphere (HGS) alongside paleoecological records and remote sensing to address long-standing challenges in understanding how new peatland areas initiate, expand, and influence climate through carbon cycling.
HGS RESEARCH HIGHLIGHT - Model simplification to simulate groundwater recharge from a perched gravel-bed river
This publication co-authored by Antoine Di Ciacca, Scott Wilson, Patrick Durney, Guglielmo Stecca, and Thomas Wöhling, investigates model simplification strategies to simulate groundwater recharge from perched gravel-bed rivers. This study leverages HydroGeoSphere (HGS) as a fully integrated 3D surface–subsurface model, alongside 2D cross-sectional and 1D analytical models, to address long-standing challenges in representing river–aquifer interactions while reducing computational demands.
HGS RESEARCH HIGHLIGHT – Vulnerability of the Saint-Charles drinking water source: portrait of the groundwater resources of the St-Charles River watershed and their links with surface water
We’re pleased to highlight this research effort, which focuses on understanding the vulnerability of the Saint-Charles River drinking water source and characterizing the groundwater resources that support it. Presented through a public-facing ArcGIS Story Map, this project delivers an accessible summary of a detailed hydrogeological study that integrates field measurements, geochemical analyses, and numerical modelling to evaluate the watershed’s current and future ability to provide safe, reliable drinking water for the City of Quebec and its surrounding municipalities.
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.
HGS RESEARCH HIGHLIGHT – Monetizing the role of water in sustaining watershed ecosystem services using a fully integrated subsurface–surface water model
This research, co-authored by David R. Lapen, Susan Preston, Tariq Aziz, and Steven K. Frey, highlights the role of subsurface water in sustaining ecosystem services during droughts. Using HydroGeoSphere (HGS), the team analyzed the South Nation Watershed (SNW) in eastern Ontario, emphasizing how subsurface water supports evapotranspiration in agricultural landscapes.
Staff Research Highlight - Water sources and threshold behaviors of streamflow generation in a mountain headwater catchment
We’re pleased to highlight this publication, co-authored by Aquanty’s senior scientist, Hyoun-Tae Hwang, which examines the water sources and threshold behaviours of streamflow generation in a mountain headwater catchment.
Staff Research Highlight - Development of a fully integrated hydrological fate and transport model for plant protection products: incorporating groundwater, tile drainage, and runoff
This research investigates how the integrated hydrological modelling of plant protection products (PPPs) such as pesticides can provide a more comprehensive understanding of their environmental behavior across groundwater, surface water, and tile drainage systems.
