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.
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.
HGS RESEARCH HIGHLIGHT – Same soil, different climate: Crop model intercomparison on translocated lysimeters
In this research highlight, researchers explored the dynamics of crop modelling across diverse climatic conditions using translocated lysimeters. The study investigates how crop models perform when applied to the same soil under different climatic regimes, shedding light on the complex interplay between soil and crop dynamics amidst changing environmental conditions.
HGS RESEARCH HIGHLIGHT – How Does Topography Control Topography-Driven Groundwater Flow?
In a study led by Xiaolang Zhang, Jiu Jimmy Jiao, Wensi Guo, researchers have comprehensively explored the mechanisms governing topography-driven groundwater flow. Their research showcases the complexities between varying rainfall patterns, topographic features, and groundwater flow dynamics, offering invaluable insights into hydrological processes.
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.
HGS RESEARCH HIGHLIGHT - Mega-Tidal and Surface Flooding Controls on Coastal Groundwater and Saltwater Intrusion Within Agricultural Dikelands
The study highlighted here makes full use of the density dependent flow modelling capabilities of HydroGeoSphere to investigate the impacts of climate change on groundwater-ocean interactions, and how sea-level rise, tides and storm-surges impact the long-term position of an upper saline plume in a coastal agricultural dikeland in Nova Scotia, Canada.
