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 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.
