Design of a downstream migration fish pass for existing hydropower plants
This paper focuses on the research and development conducted in order to design downstream fish passages along two sites equipped with a gated dam, locks and a hydropower plant. This study has been done by combining the input of on-site biological studies, hydrodynamic modelling, scale physical mode...

This paper focuses on the research and development conducted in order to design downstream fish passages along two sites equipped with a gated dam, locks and a hydropower plant.
