Formerly known as DRAME (Development and Research Applied to Water Modeling) the research group HC3 - Hydrology Climate & Climate Change specializes in water cycle modelling in natural and urban watersheds.
 
The group's work relates to the hydrology and hydraulics of watersheds and is carried out by means of numerical modeling, field studies and the observation of hydrological processes. Research activities focus on two main areas, namely hydroclimatology and the study of the impacts of major environmental changes (in particular climate change) on water resources.
