Staff Research Highlight - Improving precision in regional scale numerical simulations of groundwater flow into underground openings
The study presents a novel numerical framework to improve the accuracy of regional-scale groundwater flow simulations into underground openings, such as tunnels and deep geological repositories. Traditionally, simulating groundwater inflows into engineered underground structures has involved significant simplifications, often treating tunnels as drain features or imposing boundary conditions that fail to fully capture the physical behavior of fluid flow around these voids. This research addresses those limitations by introducing a new numerical boundary condition to simulate groundwater flow into underground openings more accurately.

HydroClimateSight Feature Highlight: Unlock Powerful Insights with HydroClimateSight’s Remote Sensing Map Layers
Modern water and land resource management relies on timely, reliable, and spatially detailed data. Aquanty’s HydroClimateSight platform empowers decision-makers by integrating a diverse set of authoritative datasets into a range of physics-based and machine-learning based hydrologic models. HydroClimateSight provides direct access to many of these datasets through the Remote Sending tab to help users better understand the datasets that go into these models. Let’s review some of the available data layers that give HCS users visual and analytical insights sourced from globally recognized organizations, government agencies, and open-data initiatives.
Research Highlight - Model simplification to simulate groundwater recharge from a perched gravel-bed river
This publication co-authored by Antoine Di Ciacca, Scott Wilson, Patrick Durney, Guglielmo Stecca, and Thomas Wöhling, investigates model simplification strategies to simulate groundwater recharge from perched gravel-bed rivers. This study leverages HydroGeoSphere (HGS) as a fully integrated 3D surface–subsurface model, alongside 2D cross-sectional and 1D analytical models, to address long-standing challenges in representing river–aquifer interactions while reducing computational demands.

Assessing the Sensitivity of Subsurface Mine-Dewatering Simulations to Surface Water Representation - Aquanty Webinar
Explore how surface water representation shapes subsurface mine-dewatering simulations in our latest webinar with Dr. Andrea Brookfield (University of Waterloo). This session highlights how climate change and surface water interactions can significantly influence dewatering strategies across mining operations.
Using HydroGeoSphere, the webinar compares conventional groundwater-only models with fully integrated surface–subsurface simulations under future climate scenarios. The results reveal important limitations of traditional approaches and show how integrated models provide more accurate insights for long-term mine water management.

HGS RESEARCH HIGHLIGHT – Vulnerability of the Saint-Charles drinking water source: portrait of the groundwater resources of the St-Charles River watershed and their links with surface water
We’re pleased to highlight this research effort, which focuses on understanding the vulnerability of the Saint-Charles River drinking water source and characterizing the groundwater resources that support it.
