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.

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.
Aquanty Featured in University of Waterloo News: Reading the signs in the streams before emergencies unfold
We’re excited to share that Aquanty has been featured in a new story from University of Waterloo News, highlighting how our hydrologic modelling and forecasting technologies are helping communities anticipate water-related risks before they become emergencies.
HGS RESEARCH HIGHLIGHT – Numerical simulation of geothermal energy transfer beneath exothermic waste rock piles
This publication, co-authored by Jasmin Raymond, René Therrien, Louis Gosselin, and René Lefebvre, which investigates how geothermal energy can be harnessed beneath exothermic waste rock piles to improve the performance of ground-coupled heat pump systems. This study leverages HydroGeoSphere (HGS) to simulate coupled subsurface fluid flow and heat transfer, addressing long-standing challenges in quantifying how enhanced subsurface temperatures generated by sulfide mineral oxidation can reduce the required length and number of ground heat exchangers.
HGS RESEARCH HIGHLIGHT – Saltwater Circulation Driven by Shoreline Curvature in Coastal Aquifers
This publication co-authored by Xuan Yu, Lanxuan He, Rongjiang Yao, Zexuan Xu, George Kourakos, Jie Yang, and Franklin W. Schwartz, which investigates how shoreline curvature influences saltwater circulation, freshwater–saltwater mixing, and submarine groundwater discharge (SGD) in coastal aquifers. This study leverages HydroGeoSphere (HGS) to perform fully three-dimensional, variable-density groundwater flow and salt transport simulations, addressing long-standing limitations of two-dimensional coastal aquifer models that neglect along-shore and lateral flow processes.
