HGS HIGHLIGHT – Estimating cumulative wastewater treatment plant discharge influences on acesulfame and Escherichia coli in a highly impacted watershed with a fully-integrated modelling approach
In this research highlight, researchers used HydroGeoSphere (HGS) to explore the impact of wastewater treatment plant (WWTP) discharge on surface water contamination in a mixed-use watershed in Ontario, Canada. The study focused on tracking acesulfame, a commonly used artificial sweetener, and Escherichia coli (E. coli), a fecal indicator, to understand how these contaminants move between surface and groundwater systems. Understanding the interactions between surface water and groundwater is critical in watersheds where WWTP discharge contributes to regional water quality concerns.
The Impact of SW-GW flow interactions for regional scale simulation of hydraulic heads: application in the south Quebec regional hydro system - Aquanty Webinar
A recording of our November 19th, 2024 webinar is now released.
This insightful session unpacks how the interplay between surface water (SW) and groundwater (GW) influences the accuracy of hydraulic head simulations in Southern Quebec, a region with significant water management challenges.
Staff Research Highlight - Climate Change Impacts on Mountain Snowpacks
We’re happy to highlight a new publication co-authored by Aquanty’s senior data scientist, Dr. Andre Erler, focused on the expected impacts that climate change will have on snow depth in mountainous regions. This research relies solely on regional climate projections and employs a very similar model configuration (WRF version 4). The WRF simulations used in this paper are described in detail in Erler & Peltier (2017).
Staff Research Highlight - Great Lakes Basin Heat Waves
We’re pleased to highlight new research co-authored by C1W collaborators at Aquanty (Andre Erler) and the University of Toronto (Dr. Richard Peltier). This new paper explores the effects of climate change and greenhouse gases on extreme heat events in the Great Lakes region.
Staff Research Highlight - Future snow changes over the Columbia Mountains, Canada, using a distributed snow model
This paper, co-authored by Andre Erler and researchers from the University of Northern British Columbia, investigates climate change impacts on snow depth using a distributed snow model called SnowModel. Snowmelt is an essential water source for communities, and seasonal snow accumulation in many regions is decreasing with each passing year. Water managers, communities, and policymakers can benefit from improved snow modeling forecasts to inform their decision making and understand vulnerabilities to their water supply systems.

HGS RESEARCH HIGHLIGHT – A Comparison of Sea-level Rise and Storm-Surge Overwash Effects on Groundwater Salinity of a Barrier Island
In this research highlight, researchers explored the impacts of storm surge overwash and sea-level rise on groundwater salinization at Assateague Island, a low-lying barrier island on the U.S. mid-Atlantic coast. The study used HydroGeoSphere (HGS) to simulate the coupled surface and subsurface flow processes that influence the island’s aquifer system. By modelling future sea-level rise and storm-surge events, the researchers aimed to better understand the long-term effects of climate change on groundwater resources, particularly the vulnerability of freshwater lenses to salinization.
Assessing Groundwater and Surface Water Contributions to Evapotranspiration in a Semi-Arid Watershed - Aquanty Webinar
A recording of our October 30th, 2024 webinar is now released.
This session delves into how groundwater (GWET) and surface water (SWET) shape actual evapotranspiration (AET) dynamics in the North Saskatchewan River Basin— a vital area for understanding water balance in semi-arid regions.
HGS RESEARCH HIGHLIGHT – Modeling low-flow bedrock springs providing ecological habitats with climate change scenarios
In this research highlight, researchers used HydroGeoSphere (HGS) to investigate the impact of low-flow bedrock springs on ecological habitats under various climate change scenarios, with a focus on the effects on aquatic species such as salamanders. These bedrock springs are critical for sustaining ecosystems, and understanding their future dynamics is essential for effective conservation.
