The Earth Observation System (EOS) provides the infrastructure needed to study and document ecosystems in the St. Lawrence River Valley (VFSL) in Quebec in order to develop a quantitative predictive model of system-wide interactions in the geobiosphère-climate of the region. A key aspect of EOS is its ability to include a combination of fixed facilities and a flexible mobile infrastructure to observe and analyze the Dynamic Terrestrial System (DES) in remote areas of Quebec. The VFSL climate is characterized by exceptional weather conditions (eg, ice storms), varied uses of land (urban, natural, etc.) and biodiversity flows (species loss and invasion).
The Aquatic Bio-optics and Biogeochemistry Laboratory enables researchers to study the effects of climate change and permafrost thawing on lake water transparency and mixing dynamics and their multiple impacts on the microbial food chain, greenhouse gas emissions, and oxythermal habitat. Research at the Aquatic Bio-Optics and Biogeochemistry Laboratory also focuses on developing optical equipment for early detection of algal and cyanobacterial blooms and other problems related to water browning.
The main objective of this project is to evaluate different final cover scenarios to reduce the production of leachate in a Saint-Nicéphore landfill, located in Drummondville, Quebec. In order to assess the percolation, the Université de Sherbrooke team proposed to build an experimental plan on the existing coverage of the site. Five lysimeters were built in 4 enclosures, that is to say areas where all the runoff water is collected in order to monitor their quantity and quality over time. The quality must be monitored due to the presence of contaminated soil in some of the scenarios under study, while the quantities are used to carry out water balances over time. This project is done in collaboration with the company Waste Management and receives financial support from WM, CRSNG and CRIBIQ.
The purpose of the BEREV is to characterize the water cycle and the surface flows (energy, water and carbon) in a boreal environment in order to increase our understanding of the hydrological and hydrometeorological processes in the presence of abundant snow, in support of a better modeling and better forestry practices. In particular, BEREV has micrometeorological equipment above the canopy. To know more, watch this webinar about the BEREV: https://youtu.be/-bbwMuuYLYg
The main equipment for characterizing the physical and geochemical properties of aquifers is a specialized Geotech 605 drilling rig. With the data collected, it is possible to model the flow of water and the transport of contaminants in aquifers. It is also possible to assess the vulnerability of aquifers to contamination, to determine the most suitable protection methods and methods of exploitation for sustainable management of the groundwater resource. This crawler drill has a real-time recording system of mechanical and electrical soil responses. It also allows soil or groundwater sampling by installing observation wells. The system has two drilling heads, one for drilling by penetration (cone penetration) in loose deposits, and another equipped with a hydraulic hammer for rotary impact drilling up to 50 m in rock and loose deposits according to the conditions.
The research conducted at the Geothermal Open Laboratory is aimed at gaining better understanding of underground heat transfer and flow phenomena for reducing technical risks of geothermal energy. It is an open access laboratory, modeled after open-source software.
The UdeS hydraulic laboratory is one of the largest in Canada. It is used as much for the courses as for the research or the realization of expertises. Numerous assemblies and several channels allow the visualization and the experimentation of almost all the phenomena of the hydraulics with free surface and under pressure. It includes a 40 hp pump, a charging system, a gauging station, channels, numerous valves and a wave channel. Measuring instruments using the latest technologies, such as acoustic doppler velocimetry, are connected to computerized data acquisition systems.
The hydraulics laboratory of the civil engineering department has several equipment to reproduce flows with free surface and load. It includes a 40 hp pump, a charging system, a gauging station, channels, numerous valves and a wave channel. Measuring instruments using the latest technologies, such as acoustic doppler velocimetry, are connected to computerized data acquisition systems. As part of research activities, specific editing can be done. Currently, we can observe a test bench to assess, in full size, the hydraulic capacity of the storm sewer grilles.
LIASHyC aims to be a world reference in the field of complex hydrogeological systems through the quality and relevance of its research and innovation, training and transfer activities. The research and innovation program focuses on fractured media hydrogeology, hydrogeology of northern and alpine regions, and characterization of hydrogeological heterogeneities. LIASHyC consists of the following parties:
- Institute of Earth Sciences of the UNIL (ISTE-UNIL)
- Center of Hydrogeology and Geothermal Energy of UNINE (CHYN-UNINE)
- Center Eau Terre Environnement of the INRS
- Department of Geology and Geological Engineering of Laval University
The Applied Geophysics Laboratory of the Department of Geology and Geological Engineering includes several geophysical equipment for the non-destructive auscultation of physical environments for Earth science needs. This equipment is supplemented by a linear thrust system with a capacity of 10000 kg to carry out penetration tests with electro-seismic piezocone with constant penetration rate. These tests provide precise but timely information on the stratigraphy of the environment studied. In order to extend this stratigraphy to the whole of a given study site, the geophysical methods of surface auscultation of the physical environments (profiles of georadar, 2D and 3D tomography of induced polarization, surveys of seismic refraction and reflection, ...) are then used.
