Decision Support System

The FIThydro DSS supports informed decision making on the design and operation of new and refurbished hydropower plants. It helps you to screen potential mitigation measures that could be appropriate for your specific hydropower scheme.


FIThydro Decision Support System

The Decision Support System (DSS) is a systematic, risk-based, open-access online assessment tool to guide environmentally (fish-) friendly hydropower production and safe fish passage, through the planning, development and operation of existing and new hydropower schemes, including the revision of permits. The innovative DSS takes individual and population-based fish damage as well as the sensitivity and conservation status of species and economic aspects into account and is generally applicable throughout different geographical regions. It encompasses scoping, impact risk-analysis, mitigation scenarios as well as socio-economic appraisal and monitoring feedback. It supports informed decision-making on the design and operation of new and refurbished HPPs, enabling the screening of potential mitigation measures that could be appropriate for a specific scheme. The DSS is closely linked to the FIThydro Wiki.
