The report D2.2 of FIThydro presents the solutions, methods, tools and devices used at test cases in the project and describes their usage, applicability and limitations. The report also describes the results from the research at the test cases themselves.

Many technologies exist to measure, improve and allow hydropower to be as fish-friendly as possible. FIThydro aims at identifying and improving these technologies as well as creating new ones. For this, different solutions, methods, tools and devices (SMTDs) are applied, tested and developed at Test Cases (i.e. hydropower plants) across Europe and in laboratories. The activities at the Test Cases can be classified into 5 topics:

  • Upstream migration
  • Downstream migration
  • Fish passage through turbines
  • Influence of hydropeaking
  • Habitat and hydromorphology

The report D2.2 describes 29 tools and methods that are used in FIThydro, ranging from Visible Implant Elastomer to TELEMAC and the Hydropeaking tool.

Next to a general description of the SMTDs, their applicability, accuracy and limitations are discussed and cross-comparisons are presented. Furthermore, the research conducted with these SMTDs and the results from the work at 14 FIThydro Test Cases are presented. Although the complete results are not yet available, it has been possible to analyse, compare and discuss the results to deduce application ranges, knowledge gaps and needs according the 5 topics listed above.

This deliverable is complementary to D2.1, which presented a survey of existing mitigation measures. These mitigation measures will be also included and updated in the FIThydro wiki (due in October 2020).
