Wetlands are increasingly seen as a form of natural green infrastructure owing to the many ecosystem services they provide. Like many effluent receiving watersheds in Canada and around the world, the Frank Lake wetland in southern Alberta provides services that support diverse user groups (municipal, industrial, non-profit, recreational). Much like other watersheds, this system is […]

One of the main safety concerns for dam structure is damage from the scour and erosion of rock mass downstream of spillways. Therefore, the design of dam spillways to discharge a wide-ranging quantity of water with minimum rock mass scour, is one of the most important issues in designing hydraulic structures that consider the energy […]

The increasing consumption of pharmaceutical to combat wide variety of diseases have caused pharmaceuticals as an emerging pollutant (EP) in water bodies and also in wastewater samples. The non-biodegradable nature of pharmaceuticals results their ineffective removal in biological systems including biological wastewater treatment units (BWTU). To combat the problem of secondary effluent from BWTU containing […]

Geophysical techniques are being increasingly used to monitor the structural conditions of dams, due to their widespread coverage and ability to detect subsurface issues, such as the development of seepage pathways. One such technique is Electrical Resistivity Tomography (ERT), which is sensitive to moisture content and porosity, meaning it can be useful for detecting areas […]

Our experiments will investigate the shedding of condensates when exposed to airflow (aerodynamic forces) in the microgravity environment. Shedding of droplets from a surface is a critical part of the dropwise condensation process to improve heat transfer. Because the use of gravity as a droplet removal technique is not available in space, the use of […]

Organic contaminants enter the marine environment through atmospheric transport, runoff into waterways, or directed disposal into the ocean. They are prone to long-range, bioaccumulation and can have adverse effects on human health and the environment. In this project, a simple and convenient extraction device developed for analysis of organic pollutants will be examined for various […]

The project is dedicated to the investigation and testing of environment-friendly, energy-efficient freezing technology for the remediation of mine-impacted water. This technology could be beneficial and economically feasible for the regions with cold weather conditions and vulnerable to anthropogenic impact. The primary research objectives of current project are to continue and advance laboratory experiments started […]

Avec les changements climatiques, il est attendu que les pluies seront plus abondantes (Alliance des ruelles bleues-vertes, 2018), ce qui risquerait d’engorger les systèmes municipaux de gestion de l’eau, qui subissent déjà une pression dans les centres urbains (Bruebach, 2019), notamment à Montréal. Or, ce projet s’intéresse au concept de ruelle bleue-verte comme infrastructure pour […]

As glaciers retreat, the reduction in area available for melting ultimately causes declines in summer streamflow. In addition, evaporation from newly formed lakes and evapotranspiration from vegetation establishment on deglaciated areas would act to further reduce summer streamflow. However, these latter processes have received little attention to date. The objective of the project is to […]

The Canadian Western Cordillera is a glaciated region within Canada which has seen significant glacial retreat due to recent climatic warming – estimated glacial volume reduction by 70% by 2100. As a result of this glacier retreat, depressions beneath are exposed (known as glacial overdeepenings) and lakes begin to form, dammed by the bedrock or […]

While most people get drinking water through underground water pipes, in some areas these pipes only provide water for a few hours each week. Globally, more than one billion people are served by these “Intermittent Water Supply Systems (IWS)”. In severely degraded systems, keeping pipes empty most of the time can reduce leakage and conserve […]

Water in lakes has a certain triple oxygen isotopic composition depending on the amount of precipitation and evaporation. Snails use oxygen from lake waters in order to mineralise their shells, thereby locking in the isotopic composition so that when snails die, they accumulate in sediments and can be analysed in order to build a record […]
