Hydraulic Mixing Cell (HMC) Training Session in HydroGeoSphere - Aquanty Webinar
We’re pleased to share the recording of our recent Hydraulic Mixing Cell (HMC) Training Session in HydroGeoSphere. Presented by Arghavan Tafvizi, HydroGeoSphere Specialist at Aquanty Inc., this practical session provides a comprehensive introduction to the Hydraulic Mixing Cell workflow and its application for analyzing surface water–groundwater interactions in integrated hydrologic models.
Using a Hydraulic Mixing‑Cell to Characterize Surface Water – Groundwater Interactions in Snow‑Dominated Catchments - Aquanty Webinar
We’re pleased to share the recording of our recent webinar, Using a Hydraulic Mixing-Cell to Characterize Surface Water–Groundwater Interactions in Snow-Dominated Catchments. This session, presented by Benjamin Frot, PhD Candidate at Laval University, explores how integrated hydrologic modelling and innovative post-processing techniques can improve our understanding of groundwater contributions to streamflow, water age, and climate change impacts in snow-dominated watersheds.
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.
HMC Tracking with HGS: Tracking Surface Water and Groundwater Contributions to Flooding in an Alluvial Aquifer - Aquanty Webinar
We’re pleased to share the recording of our recent webinar, Tracking Surface Water and Groundwater Contributions to Flooding in an Alluvial Aquifer. This session, presented by Dr. Michael Callaghan, Senior Applications Engineer at Aquanty Inc., explores how integrated hydrologic modelling can improve understanding of groundwater flooding risks— particularly during major flood events.
Focusing on the June 2013 flooding in southern Alberta, the webinar demonstrates how groundwater flow within alluvial aquifers can contribute to infrastructure damage, even when overland flood defences are in place. Using HydroGeoSphere and its Hydraulic Mixing Cell (HMC) approach, the study tracks the dynamic contributions of surface water and groundwater throughout a flood event, offering new insight into subsurface flood mechanisms and system behaviour.
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.
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 – 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 – Simulating the recession dynamics of Arctic catchments in the context of a thawing permafrost
In a recent study, researchers have made significant strides in understanding how climate warming is altering the Arctic's hydrological dynamics. The study delves into the complex relationship between permafrost thaw and groundwater flow. Traditionally, Arctic hydrology has been conceptualized as a local system, confined by the frozen ground. However, as the climate warms, permafrost begins to thaw, transitioning this system into a more interconnected network of regional aquifers. This transformation is crucial, as it alters the fundamental dynamics of water movement and storage in the Arctic.
