Fish friendly intakes

 

Hydropower operation has the potential to harness fish habitat and fish species and modern design of hydropower plants must have an aim to minimize the impact on aquatic life. 

Fish species living in the upstream area of a hydropower intake may be forced or attracted to enter the intake and the design of the intakearea and the intake itself should avoid this. Favorable design will include both mechanical and structural issues but hydraulic design influencing the motivation of the fish not to enter the intake is now the most promising approach to fish friendly design of hydropower.

The project will very much follow up from valuable findings in the recent research project SafePass. Tools and methodologies developed in this project will be used to find innovative design for intake structures and intake areas.
