AMBER Atlas: 629,955 Artificial Instream Barriers Across 36 European Countries

AMBER Atlas of Instream Barriers in Europe is a geo-referenced database of 629,955 unique artificial instream barriers across 36 European countries. It was produced by the AMBER Project, funded under the European Union’s Horizon 2020 program. The dataset includes data for ground-truthing, barrier density modeling, and analysis of barrier under-reporting, as published in Nature.

Use Cases

• Modeling river connectivity and fragmentation based on the geo-referenced barrier locations.
• Ground-truthing and validating barrier records using the results from river walkover surveys.
• Analyzing regional barrier densities and under-reporting extents across European sub-basins.
• Comparing barrier heights and densities using common river networks like HydroSHEDS.

Strengths

• Contains 629,955 unique, geo-referenced records of artificial instream barriers.
• Covers 36 European countries, providing a broad spatial scope.
• Includes ground-truthed validation data from walkover surveys.
• Data supports multiple published analyses, including figures and tables in a Nature article.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for specific component files is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
