HGS RESEARCH HIGHLIGHT – Groundwater flow reversal between small water bodies and their adjoining aquifers: A numerical experiment
This recent study uses HydroGeoSphere to investigate groundwater-surface water interactions within “kettle holes” - post glacial landscape features prevalent across Northern Europe and Northern America. These kettle holes are quite similar to lakes, but their smaller size makes them prone to drying out, which results in very dynamic and variable groundwater-surface water interactions, sometimes being subject to groundwater flow reversal between a kettle hole and the adjacent aquifer.
HGS RESEARCH HIGHLIGHT – Evaluation of Hydraulic Conductivity Estimates from Various Approaches with Groundwater Flow Models
Over several decades a wide variety of techniques have been used to estimate the hydraulic flow properties of the subsurface. Here the authors have produced heterogeneous hydraulic conductivity (K) distributions at a heavily instrumented research site using 6 distinct techniques (slight variations in some tests resulted in 9 distinct K distributions):.
HydroGeoSphere Research Highlight - "Lateral and vertical saltwater intrusion into a coastal aquifer"
Climate change is projected to substantially increase the global mean sea level, which will adversely impact coastal communities worldwide.
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.
HGS RESEARCH HIGHLIGHT – Effect of topographic slope on the export of nitrate in humid catchments: a 3D model study
Agricultural nutrient runoff refers to the movement of excess nutrients, such as nitrogen and phosphorus, from agricultural lands into water bodies such as rivers, lakes, and oceans. While nutrients are essential for plant growth, excessive runoff can have significant impacts on both human and ecosystem health.
HGS RESEARCH HIGHLIGHT – Testing high resolution numerical models for analysis of contaminant storage and release from low permeability zones
This study by researchers at the University of Guelph and Colorado State University tests out different numerical groundwater flow and transport models to simulate contamination diffusing into and subsequently out of low permeability zones.
"Climate Change Impact Analysis using HydroGeoSphere" - Aquanty Webinar
As the relevant components of the global climate (e.g. temperature and precipitation patterns/intensity) drift further from historically reliable patterns, it becomes harder and harder to rely on these historical patterns as part of hydrologic studies. This is why HydroGeoSphere is an incredibly powerful tool for long-term climate change impact analyses of hydrologic systems.
HGS RESEARCH HIGHLIGHT – Impacts of Climate Change and Different Crop Rotation Scenarios on Groundwater Nitrate Concentrations in a Sandy Aquifer
This study by researchers at the University of Guelph investigated the impacts of various crop rotation scenarios and climate change on groundwater nitrate concentrations in a 155 sq-km agricultural sub-watershed in Norfolk County, Ontario.
HGS RESEARCH HIGHLIGHT – Evaluating Climate Change Impacts on Soil Moisture and Groundwater Resources Within a Lake-Affected Region
This study investigates how climate change could impact groundwater and soil moisture within the Great Lakes Basin (GLB). Groundwater is a resource that is relied on for agriculture, industry, municipalities, and drinking water. Approximately one-quarter of the 33 million inhabitants of the GLB depend on groundwater as their primary freshwater source. Given its extreme value as a natural resource, the impacts of climate change on groundwater need to be well understood, and fully-integrated models that incorporate such large water bodies (let alone an entire basin-scale system) are rare.
