Solution to Europe's "Broken" Rivers Identified in Research Involving UCC 17th December 2020 An EU project involving University College Cork (UCC) team of researchers has identified thousands of large dams and a myriad of weirs, culverts, fords, sluices and ramps Credit: Amber International Europe has some of the "most fragmented" rivers in the world with at least 1.2 million instream barriers, according to a newly published study. An EU project involving University College Cork (UCC) team of researchers has identified thousands of large dams and a myriad of weirs, culverts, fords, sluices and ramps as the "main culprit of fragmentation". It calculates that there are at least 0.74 barriers per kilometre of stream in Europe, and has recorded same in what it describes as the "first comprehensive pan- European barrier inventory".
