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.
