The Hydroflex project aims at designing a turbine specially suited for flexible hydropower operation. Flexible operation in rivers can induce a number of negative impacts for the downstream ecosystem, and mitigation measures will be necessary. This project will aim at investigating mitigation measures and testing the effect on mitigation on the downstream river system using hydraulic modelling and current knowledge on the effect of fluctuating flow. Of particular interest is to evaluate the ACUR system developed by Pål Tore Storli at the hydropower laboratory. We will also compare this to other possible mitigation measures through comparing costs, environmental impacts of constructing the mitigation and operational issues. Main tasks:
- Review of mitigation measures and current practices.
