Our laboratory was involved in the fund raising campaign of Fondation des Ponts. In a video aimed to encourage donators to support research, Igor Paz and Rosa Vicari (HM&Co) presented their work on weather observations and forecasts through X-band radar and media mapping and big data analysis during flood events. Both research projects are supported by the Chair Hydrology for Resilient Cities that involves as partners Fondation des Ponts, Veolia and École des Ponts ParisTech.
