The FIThydro project
FIThydro addresses the decision support in commissioning and operating hydropower plants (HPP) by use of existing and innovative technologies. It concentrates on mitigation measures and strategies to develop cost-efficient environmental solutions and on strategies to avoid individual fish damage and enhancing population developments. Therefore HPPs all over Europe are involved as test sites. Read more about the FIThydro project on the official project website.
Hydropower and fish: challenges
Hydropower is a very site-specific technology developed where the topography and hydrology are favourable. All hydropower plants require construction of a dam or weir, generally obstructing fish movements. Habitat are altered by imposed changes in flow and/or sediment transport and the set of impacts can be inter-related. The magnitude of the changes in flow is to a large degree determined by the size of the reservoir, making it possible to store water from period of abundant resources to periods of lower inflow. Biology and composition of the fish population is, however, unique to each site. As such, the environmental problems and the related measures are also very specific to each location, posing challenges to presenting generic measures viable to all possible sites, and often the solution will be a combination of measures.
In general, hydropower impacts on fish can be described as:
- direct impacts
- impacts on movements
- impacts on habitat
The direct impacts could be mortality or injury caused by turbine passage or flushing of sediments, while building a dam will introduce challenges with respect to upstream and downstream migration (impacts on movements). Changes in the natural flow and sediment regime will change the habitat condition, both in the short and long-time horizon.
What is the FIThydro wiki and how do I use it?
This wiki was created to help users implement the appropriate solutions/mitigation measures for environmental problems caused by hydropower production. The mitigation measures are classified according to various parameters, such as appropriate climatic regions, which species they are aimed at, which physical condition they address, etc. Each measure has a suggested procedure with recommended methods, tools, and devices for different stages of the implementation. A number of test cases are also presented, with links to applied and relevant solutions, methods, tools and devices. Additionally, information about studies on Policy and public acceptance and estimates of the cost of implementing mitigation measures are presented. Lastly, a Decision Support System (DSS) for selecting appropriate mitigation measures has been developed. The DSS synergizes with this wiki.
