HGS RESEARCH HIGHLIGHT – Using High-Resolution Data to Test Parameter Sensitivity of the Distributed Hydrological Model HydroGeoSphere
By integrating HydroGeoSphere in this study, the researchers demonstrate its versatility in accommodating high-resolution data and conducting sensitivity analyses across different spatial scales. Precipitation emerges as the most sensitive input data, significantly influencing total runoff and peak flow rates. Additionally, the study highlights the importance of spatially distributed land use parameterization in accurately simulating evapotranspiration components and patterns.
HGS RESEARCH HIGHLIGHT – Groundwaters in Northeastern Pennsylvania near intense hydraulic fracturing activities exhibit few organic chemical impacts
In this comprehensive study, researchers investigated the potential impact of hydraulic fracturing activities on groundwater quality in Northeastern Pennsylvania, using a HydroGeoSphere model of a region with thirty gas-well pads. Modelling results suggest a low probability of systematic groundwater organic contamination in the region.

HGS RESEARCH HIGHLIGHT – Comparing alternative conceptual models for tile drains and soil heterogeneity for the simulation of tile drainage in agricultural catchments
This research highlight explores tile drainage systems within agricultural catchments, with the goal of refining hydrological modeling methodologies. The study explores the impact of soil heterogeneity on model simulations, revealing its significance at smaller scales. Overall, offering valuable insights into improving the representation of tile drainage in hydrological models, crucial for sustainable water management in agricultural landscapes.
HGS RESEARCH HIGHLIGHT – Saltwater Intrusion Into a Confined Island Aquifer Driven by Erosion, Changing Recharge, Sea-Level Rise, and Coastal Flooding
This research sheds light on the complex interactions between storm surges, reduced recharge, high erosion rates, and sea-level rise on the hydrological balance of Prince Edward Island. By leveraging the advanced capabilities of HGS, the researchers were able to test impact that climate change and future trends in coastal hydrology will have on the islands groundwater quality and the movement on the saltwater wedge underlying PEI.

HGS RESEARCH HIGHLIGHT – Simulating the recession dynamics of Arctic catchments in the context of a thawing permafrost
In a recent study, researchers have made significant strides in understanding how climate warming is altering the Arctic's hydrological dynamics. The study delves into the complex relationship between permafrost thaw and groundwater flow. Traditionally, Arctic hydrology has been conceptualized as a local system, confined by the frozen ground. However, as the climate warms, permafrost begins to thaw, transitioning this system into a more interconnected network of regional aquifers. This transformation is crucial, as it alters the fundamental dynamics of water movement and storage in the Arctic.
HGS RESEARCH HIGHLIGHT – Understanding the vulnerability of surface–groundwater interactions to climate change: insights from a Bavarian Forest headwater catchment
This study used HydroGeoSphere to evaluate the impact of climate change on streamflow and water availability within a small forested catchment in South-East Germany. Climate forecasts in the region predict a significant decrease in precipitation over the coming decades. Based on integrated hydrologic modelling of the catchment, this forecasted decline in precipitation combined with a relatively steady rate of evapotranspiration (compared to the historical period) will result in prolonged drought conditions, which in turn will result in declining groundwater levels, decreased baseflow to the upstream reaches of the stream network.
"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.
