All Island River Catchments
River Catchment boundaries in all of the island of Ireland
A dataset defining river catchment boundaries covering the whole island of Ireland, spanning both the Republic of Ireland and Northern Ireland. It provides geographic delineation of drainage basins, published via the data.gov.ie open data portal. The dataset can be used for hydrological analysis, environmental management, and planning activities that require an understanding of river catchment extents across the island as a single hydrological unit rather than divided by jurisdictional borders.
