One of the goals of the FIThydro project is to determine the financial costs of implementing mitigation measures (solutions).

Library of possible measures Min Max Unit
[Euro] [Euro]
Habitat Instream habitat adjustments Placement of spawning gravel in the river 10 100 per cubic meter
Placement of stones in the river 50 150 per cubic meter
Cleaning of substrate - ripping, ploughing and flushing 1 50 per square meter
Placement of dead wood and debris 10 150 per meter
Restoring habitat Removal of weirs 2,000 1,000,000 per weir
Construction of a 'river-in-the-river' 50 5,000 per meter
Construction of off-channel habitats 1 100 per square meter

Restoration of the riparian zone vegetation 1 50 per square meter
Fish migration Downstream Migration barrier removal 2,000 1,000,000 per project
Operational measures (turbine operations, spillway passage) NA
Sensory, behavioural barriers (electricity, light, sound, air-water curtains) NA
Fish-friendly turbines 500,000 per turbine
Skimming walls (fixed or floating) 3,000 per m3/second
Bypass combined with other solutions 10,000 25,000 per m3/second

Downstream fish protection system using electro shock technique
Bottom-type intakes (Coanda screen, Lepine water intake, etc) NA
Other types of fine screens
Vertical slot fishways
Upstream Complete or partial migration barrier removal 2,000 1,000,000 per project
Nature-like fishways 5,000 20,000 per vertical meter
Pool-type fishways 10,000 100,000 per vertical meter
Baffle fishways 5,000 100,000 per vertical meter
Fishways for eels and lampreys 600 per meter length

Off-channel reservoir storage NA
Mechanical removal of fine sediments (dredging) 5 10 per cubic meter
Minimizing sediment arrival to reservoir 150,000 per Vortex tube
Restoration in rivers Removal of bank protection NA
