The project also developed a methodology for prioritising barriers for modification or removal to improve hydromorphology and connectivity.enAnthropogenic river fragmentationRiver barriersMacroinvertebratesFish communitieseDNAHydromorphologySediment connectivityNumerical modellingEconomic analysisManagement decision-makingTechnical Report2023-09-112015-W-LS-8https://creativecommons.org/licenses/by-nc-nd/3.0/ie/
