Barrier Removal Assessment

A comparative assessment of the ecological benefits of  barrier removals across Europe

BRF will monitor 12 barrier removals across six European countries, using a harmonized and robust methodology that combines physical, biological, and social assessments. The study will evaluate how small barrier removals improve river connectivity, fish habitats, water quality, riparian ecosystems and local communities.

Supported by funding from the Open Rivers Programme, the project will also engage local teams and grantees to build monitoring capacity, ensuring that restoration efforts continue beyond the study’s duration. By generating comparative evidence across multiple barriers and countries, the project aims to inform future decision-making and promote the removal of obsolete barriers throughout Europe. The study will contribute to the ORP strategy by providing robust proof that barrier removal is one of the most ecologically beneficial and cost-effective solutions for river restoration, benefiting both ecosystems and human safety.

Methodological Approach

The project will assess the impact of small barrier removals by examining a set of indicators most likely to show positive ecological responses after removal, based on literature on low-head structures and best practices for small barrier removal.

The final project will include comparative analyses, visual documentation, and assessments of ecological and social impacts, providing a comprehensive view of the benefits of barrier removal.
