Les sites miniers en exploitation génèrent de grands volumes d’eaux contaminées. Si es eaux se déversent dans sans traitement adéquat elles peuvent devenir la source de nombreux problèmes environnementaux. La mise en place de procédées d’enlèvement économiquement acceptable et respectant les normes de rejet visant à préserver les milieux récepteurs, représentent l’un des plus importants […]

L’industrie minière présente un secteur économique très important au Canada, cependant, les différentes opérations dans la mine entrainent des impacts d’une ampleur importante sur l’environnement. Parmi les étapes de l’activité minière est le sautage en utilisant des dynamites pour excaver et extraire le minerai du gisement. Certains ne réagissent pas complétement et libèrent des éléments […]

Urban stormwater infrastructures are the first line of defense from pluvial flooding and play a key role in protecting the environment. These systems are costly to construct and would be even more expensive to replace. Therefore, high priority must be given to maintaining the physical integrity of the assets and preserve the hydraulic capacity of […]

Water in the United States is a valuable resource. It is used from everything from drinking water to tourism. However, by the 1970s, many rivers and coastal areas were severely degraded from decades of using water to assimilate pollution. After billions of dollars spent and decades of effort on all levels of government, the increasing […]

NORAM Engineering and Constructors have a technology called salt splitting. This technology is used to produce caustic soda and sulfuric acid. However, the presence of fluoride in this technology can cause the breakdown of the coating on the titanium anode, which can cause premature anode failure. As replacing these titanium anodes can incur significant costs, […]

Since the 1960s, the lands of several indigenous communities such as the Fort McKay Métis have been largely impacted by open mines and steam assisted gravity drainages (SAGDs). Such oil sands operations have disturbed large areas, changed geology, hydrogeology, hydrology, aquatic and terrestrial environment, and created a linear disturbance. This research project will map and […]

Chaque stade glaciaire modifie le paysage. Lorsque les glaces se retirent, le nouveau paysage émerge, le niveau marin augment et les eaux glaciomarines envahissent et submergent les anciens terrains glaciaires. Tracer la limite marine postglaciaire peut révéler d’importantes connectivités hydrologiques et des échanges entre les écosystèmes terrestres et marins qui ont eu lieu et qui […]

Water is vital for life; it is a resource we interact with daily and rely on implicitly. Our reliance on water resources is why water pollution is a global concern. One risk to water quality is elevated levels of toxic trace metals. While metals occur naturally in aquatic environments, human activities can increase natural concentrations […]

Numerical simulation is a cornerstone of modern science and industry, and is used in many facets of our everyday lives. While many of us are familiar with short-term weather forecasting, substantially more computational effort is dedicated to longer-term simulations of the Earth’s ocean and atmosphere, for climate and other reasons. In such simulations, certain properties […]

In the pipeline industry, the heat shrink sleeves (HSS) are the protective layer usually composed of two layers, namely, an adhesive layer and a crosslinked backing layer such as polypropylene (PP) or polyethylene (PE). In order to maintain the desired properties of HSS, each of the layers must maintain their properties during processing, storage, and […]

L’exploitation de la centrale hydroélectrique Romaine-1 cause sur la rivière Romaine des fluctuations du débit susceptible d’entraîner le déplacement des saumons juvéniles en dehors de leurs habitats préférentiels. Il est donc essentiel de déterminer si le mode de gestion actuel des débits permet aux saumons juvéniles de se maintenir dans leurs habitats. Pour étudier la […]

Arctic temperatures are increasing twice as fast than the global average. In fjordic ecosystems of Svalbard, the Atlantification, the process leading to warmer conditions in the area impose new challenges to Arctic living community. Those changes alter cryosphere regime (i.e., ice component covering the surface) and associated species habitats. The black-legged kittiwake is a predator […]
