HGS RESEARCH HIGHLIGHT – Quantifying the effects of water management decisions on streambank stability
This publication co-authored by Q. Wei, A. Brookfield, and A. Layzell, investigates how water management decisions influence streambank stability by altering subsurface hydrologic conditions. This study leverages HydroGeoSphere (HGS), coupled with the surface water operations model OASIS, to address long-standing challenges in linking reservoir operations, groundwater pumping, and hydrologic dynamics to the physical mechanisms driving streambank failure.
HydroSphereAI Case Study: Nanaimo River Near Cassidy – January 2026 High-Flow Event
On January 12, 2026, the Nanaimo River near Cassidy (Water Survey of Canada Station 08HB034) experienced a significant high-flow event, cresting at the 2-year flood mark. Winter storm systems sweeping across Vancouver Island brought prolonged precipitation to the watershed, driving river discharge well above average levels for the season. This case study highlights how an early release version of HydroSphereAI (HSAI) tracked the event and how this information could be used by stakeholders and water managers.
HGS RESEARCH HIGHLIGHT – Stable Water Isotopes Improve Calibration and Flow path Identification in Integrated Hydrological Model
This publication co-authored by Omar Ashraf Nimr, Hannu Marttila, Anna Autio, and Pertti Ala-Aho, investigates how stable water isotopes can improve calibration, uncertainty reduction, and flow path identification in fully integrated surface–subsurface hydrological models. This study leverages HydroGeoSphere (HGS) to explicitly simulate both hydrologic processes and isotope transport, addressing long-standing challenges related to equifinality and internal process realism in groundwater–surface water modelling.

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 – Modeling the water use associated with energy consumption changes on saltwater intrusion in the Pearl River estuary, China
This research investigates how increased energy consumption and associated changes in water use impact saltwater intrusion in the Pearl River Estuary— one of China's most economically vital and environmentally vulnerable regions.
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.
