HGS RESEARCH HIGHLIGHT – Three‐Dimensional Analysis of Heat Tracer Transport With High‐Resolution Subsurface Heterogeneity Characterization in a Complex Aquifer System

We're pleased to highlight this publication by Chenxi Wang and colleagues, co-authored by Aquanty's Steven Berg and Hyoun-Tae Hwang, which investigates how high-resolution characterization of subsurface heterogeneity can improve predictions of heat tracer transport in complex aquifer systems. The study leverages HydroGeoSphere (HGS) to simulate three-dimensional groundwater flow and heat transport, evaluating how different methods of representing hydraulic conductivity influence the ability to reproduce observed tracer behaviour in highly heterogeneous glaciofluvial deposits.

HGS RESEARCH HIGHLIGHT – Modeling E. coli fate and transport in and around a cattle pond

We're pleased to highlight this publication by Alexander Yakirevich and colleagues, which explores the fate and transport of Escherichia coli (E. coli) in and around a cattle pond using HydroGeoSphere (HGS). The study presents a fully integrated surface water–groundwater model that simulates watershed-scale hydrology alongside microbial transport, providing new insight into how livestock activities influence water quality in agricultural watersheds.

HGS RESEARCH HIGHLIGHT – Modeling a geologically complex volcanic watershed for integrated water resources management in Mt. Fuji, Japan

This publication presents a three-dimensional geological and integrated hydrological modelling dataset developed for the Mt. Fuji volcanic watershed in Japan. This study leverages HydroGeoSphere (HGS) to simulate coupled surface–subsurface flow and transport processes in a geologically complex volcanic catchment, addressing long-standing challenges in representing groundwater flow pathways and hydrologic interactions in structurally heterogeneous mountain environments. The resulting dataset provides a physically consistent modelling framework to support interdisciplinary water resources research and scenario-based hydrologic simulations.

Flee From Parsimony: Escaping the Boundary Condition Paradox in Groundwater Modelling - 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 – Effects of Creek Topology on Salinization of Coastal Marsh Due To Storm Surges

We’re pleased to highlight this publication, co-authored by Shuangshuang Yu and colleagues, which investigates how creek network topology influences storm-surge-driven salinization in coastal marsh systems. This study leverages HydroGeoSphere (HGS) to simulate coupled surface–subsurface flow and salt transport processes under variable-density conditions, addressing long-standing challenges in understanding how geomorphology controls vertical saltwater intrusion and recovery in marsh environments.

HGS RESEARCH HIGHLIGHT – Diffusion-Controlled Solute and Isotope Transport in the Milk River Aquifer System, Alberta, Canada: Implications for Dating Old Groundwater

We’re pleased to highlight this recent publication by Stephanie L. Musy and colleagues, which investigates how diffusion-controlled solute transport influences groundwater age interpretations in the Milk River Aquifer (MRA), a transboundary aquifer system spanning southern Alberta and northern Montana. The study combines multiple environmental tracers, including krypton-81 (^81Kr), chlorine-36 (^36Cl), stable chlorine isotopes (^37Cl/^35Cl), and radiocarbon (^14C), with HydroGeoSphere (HGS) simulations to better understand groundwater residence times and the processes controlling tracer distributions in old groundwater systems.
