Assessing the effects of stream restoration requires long-term monitoring, before and after restoration. Today, it is still difficult to evaluate and to predict the effects of restoration projects. Long-term monitoring of physical restoration actions are opportunities for testing quantitative ecological models, e.g. physical habitat models based on biological response to the hydraulic habitat (e.g.,


Together with the University of Lyon, we coordinate the scientific monitoring of the Rhône River restoration (Rhoneco program: made over several decades and in 8 reaches of the river. The restoration combined increased minimum flow increases below dams and increased connectivity of many floodplain channels. Fish and invertebrate responses are partly predictable by eco-hydraulic models.
