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 – 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.

HGS RESEARCH HIGHLIGHT – Climate Change Alters Post-Surge Recovery of Coastal Aquifers

This publication co-authored by Satoshi Tajima, René Therrien and Philip Brunner investigates how climate change influences the recovery of coastal aquifers following storm surge events. This study leverages HydroGeoSphere (HGS) to simulate coupled groundwater flow and variable-density salt transport, addressing long-standing challenges in understanding how coastal aquifers respond to storm-driven seawater intrusion and how recovery dynamics may change under future climatic conditions.

HydroSphereAI Case Study: Spring Freshet Forecasting for Hydropower Risk Awareness – Vermilion River Ontario (Station: 02CF011 - VERMILION RIVER NEAR VAL CARON) – April 2026

Between April 15 and April 22, 2026, watersheds across Greater Sudbury experienced a significant spring flood event driven by rapid snowmelt and sustained rainfall. A Flood Warning issued by Conservation Sudbury highlighted elevated inflows across the region, including the Vermilion River system near Val Caron.

While the Vermilion River is not a regulated hydropower system, Water Survey of Canada Station 02CF011 (Vermilion River near Val Caron) provides a comparable watershed area for understanding naturalized inflow dynamics relevant to hydroelectric operations across northern Ontario.

This case study demonstrates how HydroSphereAI (HSAI) captured the timing and magnitude of peak flows during a complex spring freshet event, and how similar forecasting capability can support hydropower decision-making.
