Habitat modeling

Example of habitat-flow curve obtained by our models, used to identify minimum flows below dams The Dynam team is specialized in hydraulic habitat models. Habitat models link hydraulic models of river reaches with biological models reflecting fish and invertebrates preferences for their hydraulic microhabitat. Our models (e.g. estimhab, stathab) are routinely used for defining legal …

Stream physical restoration and long-term monitoring

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., http://www.irstea.fr/estimhab) …
