FIThydro Deliverable 1.1
Metadata overview on fish response to hydropower
31 October 2017 | Lead: INBO, FVB.IGB

In this report a fish species classification system according to their species-specific sensitivity against mortality was developed to assess the impacts of hydropower plants on fish species more effectively. The compiled metadata overview comprises 192 fish and lamprey species that are classified according to their sensitivity against mortality. The result allows for an objective and comprehensible comparison of the inherent biological sensitivity of fish and lamprey species and identified in total 40 taxa of high susceptibility to disturbance covering all biogeographic regions of Europe.

Fish Population Hazard Index
31 October 2019 | Lead: FVB.IGB

Assessing the impact of hydropower plants (HPP) on different fish species and communities is a key-component supporting decisions during the commissioning process and operation of HPPs. The Fish Population Hazard Index presented in this publication is a decision and management tool for environmental impact assessment of hydropower plants. The index allows risk assessment while considering site-specific effects of single hydropower plants, fish species sensitivity against mortality as well as overarching environmental and societal development targets for the respective water body.

FIThydro Deliverable 1.4
Cumulative Impact Assessment
31 October 2019 | Lead: FVB.IGB

Assessing the impact of hydropower plants (HPPs) on different fish species and communities is a key-component of supporting decisions during the commission and operation of hydropower facilities. However, HPPs are often not stand alone in a river system and therefore, cumulative effects of consecutive HPPs as well as in combination with barriers without electricity generation have to be accounted for. The aim of this deliverable is to conduct an Environmental impact assessment (EIA) of consecutive hydropower plants (HPPs) based on fish to inform decision support and mitigation planning. Here we provide evidence based guidance on assessment of, and management strategies for, the potential for cumulative effects from hydropower developments.

FIThydro Deliverable 3.1
Guidelines for mortality modelling
31 October 2019 | Lead: TUM

One way of fish downstream migration is passage through the turbine at hydropower installations, which can be related to injury and mortality, caused by several damage mechanisms. This guideline presents both basic and more detailed methods to quantitatively assess the fish passage through a hydropower turbine.

D3.4 – Enhancing and customizing technical solutions for fish migration
31 October 2020 | Lead: IST-ID

Fish management and conservation in regulated rivers is often hampered by hydropower plants (HPPs), dams, weirs and spillways. Such structures may block or delay up- and downstream fish movements, and cause injury or mortality of fish when passing turbines, weirs or spillways. Although upstream fish passage remains an active research area, it is more developed than downstream fish passage technologies which still pose great challenges to scientists, engineers, authorities and HPP operators due to the lack of design standards and related basic information on the behaviour of various fish species. To fill these knowledge gaps and provide safe downstream fish movement at hydropower and water intakes, the FIThydro partners ETH Zurich, CNRS and TUM have improved or developed five different innovative physical or behaviour-based technical solutions on the basis of systematic laboratory and/or field investigations.

31 October 2019 | Lead: Sintef

Possible mitigation measures for mitigating the impacts of hydropower on fish are scored with respect to their suitability for mitigating challenges and problems. A matrix also shows how different mitigation measures can be combined. Additionally, the framework for using Bayesian networks to identify potential combinations of mitigation measures is described.

General Cost Figures for Relevant Solutions, Methods, Tools and Devices
30 April 2021 | Lead: Sintef

FIThydro aims to identify cost-effective mitigation measures, which foster self-sufficient fish populations and increase hydropower production. In this report, we describe the financial and economic costs associated with mitigation according to the categories of flow, sediment management, upstream and downstream fish migration and habitat enhancement. Our report summarizes average costs for mitigation measures based on data collected from the literature and a FIThydro questionnaire filled out by European hydropower operators. In addition, we describe factors which affect the variation in these costs, especially when costs from case studies are unavailable. Cost data were reported as total investment cost per unit, investment per project or for individual measures

Review of policy requirements and financing instruments
31 October 2017, Revision: 23 January 2018 | Lead: EI

This report investigates and summarises the regulatory landscape influencing actions relevant to environmental improvements in the context of planning and operating hydropower plants on a European and national level. Emphasis is given to the requirements of the EU Water Framework Directive, nature protection policies and policies on renewable energy and climate change adaptation, thereby outlining opportunities, barriers and challenges in reaching multiple environmental objectives. Next to EU legislations, national policies of eight European countries are reviewed. Additionally, the use of financing instruments in different EU countries for providing the necessary support to promote and sustain ecologically compatible hydropower production are looked into.

Stakeholder feedback on tools and products of FIThydro
31 October 2019 | Lead: EI

In 2018, the Horizon2020 project FIThydro, Fishfriendly Innovative Technologies for Hydropower, hosted regional stakeholder workshops in four test case regions, with different geographical, climatic and hydropower-related characteristics across Europe. The workshops offered a platform for consultation and exchange between FIThydro members and external stakeholders on the key open issues on important questions relevant to the assessment and planning of fish-friendly hydropower plants. This report summaries the feedback received from the stakeholders during the four regional stakeholder workshop on: key problems and open questions for the assessment and planning of fish-friendly hydropower production, typical approaches and applied solutions as well as recommendations and requests to the FIThydro project.

FIThydro Deliverable 5.4
Decision Support System for environmentally friendly hydropower
30 September 2020 | Lead: EI

The final FIThydro decision-support tool is based on the project management approach and outlines the steps that should be undertaken for the initial screening of a project to appraise the impacts, risks and scope options for further diagnosis and mitigation. Question catalogues, risk assessments and filtering tools are produced which cover aspects of ‘initial screening’, ‘ecological impacts’, ‘environmental status’, ‘mitigation measures’, and ‘risk and uncertainty’. Taken together, these aid the production of a project screening/scoping report designed to provide a systematic approach to decision-making for proposals relating to hydropower schemes and their mitigation. The Decision Support System (DSS), is presented in the form of an open access web-based tool which utilises and showcases some of the tools and outputs produced by the FIThydro project and which will act as a structured gateway to the wider project results.
