HGS RESEARCH HIGHLIGHT – Fractal Behaviors of Hydraulic Head and Surface Runoff of the Nested Groundwater Flow Systems in Response to Rainfall Fluctuations
In this paper the authors have undertaken a comprehensive investigation into the behavior of nested groundwater flow systems (NGFS) in response to rainfall fluctuations and their influence on surface runoff. Through the utilization of a fully coupled variably saturated groundwater-surface water model alongside spectral analysis, the team delves into the fractal characteristics of hydraulic head and surface runoff across different scenarios.
"Using Wetlands to Flatten the Hydrograph" - Webinar
We were so pleased to see a presentation featuring HydroGeoSphere at this year's Latornell Conservation Symposium. The presentation (“Using Wetlands to “Flatten the Hydrograph”) was delivered by representatives from Ducks Unlimited Canada (DUC), and focused on a recent collaboration between DUC, Ontario Power Generation (OPG) and Aquanty. At the center of the project is an advanced integrated hydrologic model of the Dog Lake watershed in Northern Ontario.
Manitoba Cooperator - Field-level water forecasts: There’s an app for that
The Manitoba Cooperator has written an excellent article (with comments from Dr. Steve Frey, Aquanty’s Director of Research Services) which reviews some of the new technology driven initiatives to manage water resources throughout Manitoba, with a specific focus on the newly developed MFGA Aquanty Forecasting Tool - a real-time hydrologic forecasting system for decision-support around water movement, soil health, climate risk assessment & mitigation in the Assiniboine River Basin and Pembina River watersheds.
HGS RESEARCH HIGHLIGHT – Managing climate change impacts on the Western Mountain Aquifer: Implications for Mediterranean karst groundwater resources
A new study investigates the impact of climate change on water availability within a 9000 sqkm karstic aquifer in Israel and the West Bank, and couples HydroGeoSphere to a soil-epikarst water balance model.
HydroGeoSphere at the EGU23 General Assembly
HydroGeoSphere is usually well represented at the annual European Geoscience Union’s General Assembly, but 2023 might be a new record with 10 presentations which relied on the integrated hydrologic modelling capabilities of HGS.
HGS RESEARCH HIGHLIGHT – Disentangling runoff generation mechanisms: Combining isotope tracing with integrated surface/subsurface simulation
A new study co-authored by researchers at Hohai University and Aquanty Staff introduces an effective way to track runoff generation in a headwater catchment by combining isotopic tracer analysis and integrated hydrologic modelling using HydroGeoSphere.
HGS RESEARCH HIGHLIGHT – Evaluating Domestic Well Vulnerability to Contamination From Unconventional Oil and Gas Development Sites
This study by researchers at Yale University and the Institute of Technology investigates how vulnerable groundwater wells are to contamination by the growing unconventional oil and gas development industry, which is expanding quickly and, in some cases, negatively impacting groundwater quality and posing a risk to public health by contaminating drinking water sources.
HGS RESEARCH HIGHLIGHT – Landscape restoration after oil sands mining: conceptual design and hydrological modelling for fen reconstruction
This study by researchers at the University of Waterloo investigates whether fen peatlands could be reconstructed on post-mine sites. Oil sand extraction can be very harmful to the natural land surface and can have lasting impacts on local ecosystems. This paper focuses on the fen peatlands that cover 65% of the landscape in Fort McMurray, Alberta. Our ability to reinstate these peatlands after mining operations has not truly been tested at large scales, and there are many uncertain factors that can impact reclamation plans for these sensitive wetlands.
HGS RESEARCH HIGHLIGHT – Potential influence of climate change on ecosystems within the Boreal Plains of Alberta
This paper by researchers at the University of Alberta discusses the possible impacts of climate change in the Boreal Plains in Northern Alberta, Canada. The sensitive ecosystems in this area have developed under a delicate water balance, while climate change and warming temperatures threaten to shift water availability. This study looks at ponds, peatlands with sparse black spruce, and hillslopes with predominantly aspen forests as the features of focus.
HGS RESEARCH HIGHLIGHT – Numerical simulations of water flow and contaminants transport near mining wastes disposed in a fractured rock mass
This study uses HydroGeoSphere simulations to model unsaturated water flow and contaminant migration in a mining context, specifically the reclamation of open pits with mine waste products. Fractured rock masses are important to study as fractures present preferential flow paths that can promote contaminant transport.
