Les fleuves représentent l’une des plus grandes ressources naturelles, sociales et économiques au monde. Figures emblématiques du cycle de l’eau, les fleuves jouent un rôle de premier plan dans la régularisation du climat, le développement urbain, l’agriculture et les échanges économiques. Par exemple, le fleuve Saint-Laurent draine à lui seul plus d’un quart des réserves […]

While rivers are an important and highly visible pathway for freshwater to reach the ocean, another less noticeable, but also important, pathway is the discharge of groundwater from the sea floor. This phenomenon, known as Submarine Groundwater Discharge (SGD), is significant to the coastal ocean because it can carry water-based nutrients and pollutants into the […]

Pharmaceuticals are considered intractable and easily transported into the water system. As a result, wastewater treatment plants (WWTPs) are unsuccessful in completely removing these contaminants. The successful removal of these pharmaceuticals depends on the removal and purification technologies that are being used and the physiochemical properties exhibited by these pharmaceuticals. Recent research from Canada concludes […]

Keeping the lights on for over 4 million people across the province takes a lot of talented people doing many different jobs, from working deep in a generating station, atop a power pole, or behind a desk. We’re working on upgrading transmission lines, building new substations, and investing in our hydroelectric generation facilities. It’s our […]

The climate warming currently affecting the Arctic is two to three times faster than anywhere else, with profound consequences for natural ecosystems and communities. Notably, thawing permafrost remobilizes organic matter (previously trapped in the soil) that underlies the production of greenhouse gases such as carbon dioxide and methane, which in turn helps amplify the ongoing […]

La planification des apports hydriques est primordiale pour la production d’hydroélectricité. C’est pourquoi Hydro-Québec vise à continuellement accentuer la performance de ses modèles hydrologiques. Pour ce faire, plusieurs paramètres journaliers sont utilisés, tel que l’humidité des sols. Grâce aux travaux de recherches préalables, il a été possible de proposer une méthode d’utilisation des données brutes […]

Avec l’avènement de l’ère numérique, accompagnée d’une automatisation et d’une puissance de calcul toujours croissante, le devenir des interactions humains-machines est appelé à des changements inéluctables. Le domaine de l’hydrologie prévisionnelle n’est pas indifférent à cette nouvelle réalité en regard des progrès constants de l’intelligence artificielle. L’automatisation et la redondance dans les systèmes de prévisions […]

Carbon dioxide is produced from the combustion of fossil fuels and as a by-product of many chemical processes. The increasing concentration of CO2 in the atmosphere has now been decisively linked to global climate change. The use CO2 as a carbon-building block has attracted much attention due to its low cost, ease availability, and its […]

This project is a collaboration between Drs. Jennifer Provencher, Jesse Vermaire, and Christina Davy at Carleton University in which the two student interns will quantify microplastic contents in various environmental samples to improve our understanding of the fate of microplastics in the environment. The students will learn to assess microplastics in environmental samples (e.g. scat, […]

Sediment transport in gravel-bed rivers controls the river morphology, aquatic habitat, and landscape evolution. The sediment supply together with the flow dictates the amount and texture of the supplied sediment to the channel and likely influences the transport rates, bed stability, and evolution of the bed surface. However, the previous research mainly focused on the […]

This project focuses on developing a mixed wettability surface to improve the freshwater yield of a solar thermal desalination system. The solar desalination system that will be used for this project is the solar still system. The objective is to find the optimized ratio of high wettability to low wettability area on a polymeric surface […]

The amount of water and sediment entering a river control the nature of its flow. In landscapes vulnerable to climate change, e.g., changes in precipitation, hydrology, or the disappearance of glaciers, this could result in significant changes in water and sediment inputs to rivers. The consequence of this may be down-stream flooding with negative impacts […]
