Research areas


Development, test and transfer of hydraulic habitat models predicting the biological impacts of flow management in streams. Models apply at the reach and at the catchment scales. Statistical habitat models and software are currently used by consultants for defining environmental flows, in France and elsewhere.


International comparisons of relations between the biological traits of communities (fish, macro-invertebrates) and the physical habitat in streams.


Long-term tests of the effects of physical restoration of rivers on aquatic communities (e.g. Rhône River restoration;
