The Surface and Ocean Topography (SWOT) mission, scheduled for launch in the fall of 2021, is an imaging altimeter that will track lakes, reservoirs and rivers with unparalleled accuracy to date. This information will be particularly useful for closing the water balance of these water bodies, for calibrating hydrological and hydraulic models and for assisting with reservoir management. Chair members are involved in two studies on SWOT. The first concerns the potential of this satellite to calculate inflows and for the assimilation of water levels in a hydrodynamic model. This is the project of master’s student Sébastien Langlois. The study site is the Eastmain reservoir in Quebec. The second is the study of the hydrodynamic regime of the Peace-Athabasca Delta in northeastern Alberta, a project funded by the Canadian Space Agency. In both studies, chair members use a simulator developed by the Jet Propulsion Laboratory to produce SWOT images until real images are acquired!
