Hydro turbine research

Fishtek have conducted extensive monitoring of low head hydro power turbines (Archimedean Screw),  involving live fish trials, fish behaviour at the intake, outflow and within the turbine chamber. See video footage

Assessment of the turbines leading edge lead to the development of fish friendly compressible bumpers to mitigate the effects of higher impact speeds on the largest screw turbines now in use. See reports
 
For more information on Compressible bumpers, contact fishtek.
