HGS RESEARCH HIGHLIGHT – Impact of River Morphology on River–Groundwater Exchange in Braided River Systems
We're pleased to highlight this publication by Thomas Wöhling, Moritz Kraft and Antoine Di Ciacca, which investigates how flood-driven changes in braided river morphology influence river–groundwater exchange and aquifer recharge. Using HydroGeoSphere (HGS), the researchers developed fully coupled surface water–groundwater models of two braided river systems in New Zealand to isolate the effects of changing riverbed morphology before and after major flood events. The study demonstrates that morphological changes alone can significantly alter both recharge to shallow braidplain aquifers and subsequent recharge to regional groundwater systems.
Staff Research Highlight - Water Balance and Flow Tracer Application Using a Fully Integrated Hydrologic Model in a Pilot-scale Oil Sands Pit Lake Catchment
We're pleased to highlight this new publication by Aquanty staff, including Arghavan Tafvizi, James Ehrman, Ali Sharifinejad, Diana Zhang, Michael Callaghan, Steven Berg and Killian Miller, along with our collaborators at Suncor Energy Mike Wang, and Xiaoying Fan. This paper demonstrates the use of HydroGeoSphere (HGS) and the Hydraulic Mixing Cell (HMC) method to better understand water movement within a constructed end pit lake watershed. Using the Lake Miwasin Watershed in northern Alberta as a pilot-scale study site, the researchers developed and calibrated an integrated hydrologic model to simulate surface water, groundwater, lake levels, and evapotranspiration, while using HMC to identify how different areas of the watershed contribute to lake inflow under changing seasonal and climatic conditions.
MFGA Press Release - Healthy Grasslands Are Major Key to Future Ground Water Challenges and Climate Resilience
The Manitoba Forage and Grassland Association (MFGA) has released findings from a recent study with Aquanty examining how climate change could affect water resources and agricultural landscapes in southern Manitoba through 2050 and 2100.
The study, supported through Manitoba Environment and Climate Change Climate Action Funding, used the MFGA Aquanty Model to examine future climate conditions across three previously modelled watersheds: Pembina Valley, Swan Lake, and Oak River. The results highlight the increasingly important role that healthy grasslands and groundwater recharge could play in helping agricultural landscapes build resilience to future climate conditions.
HGS RESEARCH HIGHLIGHT – Modeling a geologically complex volcanic watershed for integrated water resources management in Mt. Fuji, Japan
This publication presents a three-dimensional geological and integrated hydrological modelling dataset developed for the Mt. Fuji volcanic watershed in Japan. This study leverages HydroGeoSphere (HGS) to simulate coupled surface–subsurface flow and transport processes in a geologically complex volcanic catchment, addressing long-standing challenges in representing groundwater flow pathways and hydrologic interactions in structurally heterogeneous mountain environments. The resulting dataset provides a physically consistent modelling framework to support interdisciplinary water resources research and scenario-based hydrologic simulations.
HGS RESEARCH HIGHLIGHT – How Does Rewetting Propagate Through Restored Peatlands? An Integrated Surface–subsurface Modelling Analysis of Water–table Dynamics
We’re pleased to highlight this publication, which investigates how peatland restoration alters groundwater table dynamics across drained boreal peatlands using fully integrated hydrologic modelling. This study leverages HydroGeoSphere (HGS) to simulate coupled surface–subsurface flow processes and evaluate spatial patterns of groundwater response following ditch blocking and rewetting interventions, addressing long-standing challenges in predicting restoration outcomes across heterogeneous peatland landscapes.
Aquanty Featured in WaterPower Canada Guest Blog: Navigating Climate Change in Hydropower
We’re pleased to share that Aquanty recently contributed a guest blog post to WaterPower Canada, authored by Dr. Andre Erler, Senior Climate Scientist at Aquanty. The article “Harnessing Advanced Hydrologic Models to Help Canadian Hydroelectric Operators Navigate Climate Change” explores how advanced hydrologic modelling and forecasting tools can help Canadian hydroelectric operators navigate increasing uncertainty driven by climate change.
HGS RESEARCH HIGHLIGHT – A hydraulic mixing-cell method to quantify the groundwater component of streamflow within spatially distributed fully integrated surface water–groundwater flow models
This research highlight co-authored by D. Partington, P. Brunner, C.T. Simmons, René Therrien, A.D. Werner, G.C. Dandy, and H.R. Maier, introduces a hydraulic mixing-cell (HMC) method to accurately quantify the groundwater component of streamflow within fully integrated surface–subsurface hydrologic models. This study leverages HydroGeoSphere (HGS) to address long-standing challenges in decomposing streamflow generation mechanisms without relying on tracer transport simulations or simplifying assumptions about groundwater discharge.
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.
