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 – Three‐Dimensional Geostatistical Inverse Analyses of Transient Head and Temperature Data From a Long‐Term Heat Tracer Test
We’re pleased to highlight this staff research highlighted which investigates how three-dimensional geostatistical inverse modelling can improve characterization of subsurface heterogeneity in groundwater systems. This study leverages HydroGeoSphere (HGS) to simulate fully coupled groundwater flow and transport processes within a stochastic inversion framework, addressing long-standing challenges in estimating spatially distributed hydraulic conductivity fields from limited observational data.
Advances in HydroGeoSphere (HGS) Over The Last Decade - Aquanty Webinar
We’re pleased to share the recording of our recent webinar exploring the evolution of HydroGeoSphere (HGS) — from its origins as an ambitious integrated hydrologic modelling experiment to a widely trusted, industry-leading platform for groundwater and surface water simulation.
Presented by Dr. Hyoun-Tae Hwang, Director of HydroGeoSphere at Aquanty Inc., this session offers a comprehensive retrospective on the development of HGS since its initial launch in 2002 and its continued advancement under Aquanty since 2012. The webinar highlights key milestones, technical innovations, and the expanding capabilities that have positioned HGS at the forefront of hydrological modelling.

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.
