Staff Research Highlight - Quantifying the potential of using Soil Moisture Active Passive (SMAP) soil moisture variability to predict subsurface water dynamics

Aquanty staff investigate the potential for using near-surface soil moisture measurements from the Soil Moisture Active Passive (SMAP) satellite to predict subsurface soil moisture and groundwater storage dynamics. This research offers valuable insights into how satellite-based soil moisture data can inform large-scale hydrological modelling and support more effective water resource management.

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.

Staff Research Highlight - Steady-state density-driven flow and transport: Pseudo-transient parameter continuation

Co-authored by Aquanty’s senior scientist, Hyoun-Tae Hwang, this research presents a new numerical approach for efficiently solving steady-state density-driven flow and transport equations— an important challenge in groundwater modelling, particularly for coastal aquifers affected by seawater intrusion. The research introduces a hybrid technique called pseudo-transient parameter continuation (PTPC), which combines the robustness of pseudo-transient continuation (PTC) methods with the computational efficiency of parameter continuation (PC) strategies.

HydroClimateSight Feature Highlight: Understanding Ensemble vs Deterministic Forecasting in HydroSphereAI

We’re excited to announce that short-range streamflow forecasting is now available in HydroSphereAI! Our new short-range forecasts offer detailed predictions for the day ahead with hourly output intervals. To address the lack of uncertainty information typical of deterministic systems, we’ve introduced a lagged ensemble approach, giving you a clearer picture of forecast confidence in the near term.

HGS RESEARCH HIGHLIGHT – Source Water Protection in Quebec City: Using an integrated 3D hydrological model to investigate surface water-groundwater interactions

The research, presented as a poster by Benjamin Frot at EGU 2025, explores the use of HydroGeoSphere (HGS) to investigate surface water–groundwater interactions in the Saint-Charles River watershed, which supplies drinking water to Quebec City. With a focus on source water protection, the study addresses the challenges posed by increasing urbanization, contamination from septic systems and road salts, and reduced water availability during low-flow periods. The work is part of a larger project aimed at evaluating the vulnerability of Quebec City's main surface water intake.
