Session C3: An Innovative Solution for the Poutes Dam to Reconcile Respect for Biodiversity and Need for Renewable Energy
Abstract: Located on the River Allier (France), the largest upstream tributary of the Loire River which is one of the longest river systems in Europe in which Atlantic salmon (S. salar) spawning migration occurs, the dam of Poutès was the scene of conflicts for decades. Outcome of a consensus betwee...

Innovative hydraulic modeling (LSPIV) is a valuable aid in the design. Concomitantly with the design of the new dam, a major scientific monitoring program was initiated to measure the environmental gain of this project on the salmon population, on sediment transport and fish habitat and on the holobiotic fish population.
