[email protected] Abstract. Determining the bathymetry of lakes is important to assess the potential and the vulnerability of this valuable resource. The dilution and circulation of nutrients or pollutants is largely dependant on the volume of water and the incoming and outgoing fluxes, while the degree and frequency of mixing depends on the water depth. The bathymetry of lakes is also important to understand the spatial distribution of sediments, which in turn are valuable archives of natural hazards and environmental change.
