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.
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.
HGS RESEARCH HIGHLIGHT – Towards a climate-driven simulation of coupled surface-subsurface hydrology at the continental scale: a Canadian example
This study is an excellent example of how a physics-based approach to simulating integrated hydrology with HydroGeoSphere allows researchers to overcome the limitations of data scarcity. Allowing water to flow naturally (or as ‘naturally’ as possible for a digital environment) also simplifies the calibration process, as a well conceptualized watershed scale model should be able to accurately represent the integrated hydrology of the watershed inherently.
