Water Framework Directive Catchments

Environment Spatial


The EU Water Framework Directive (2000/60/EC) (WFD) establishes a framework for the protection, improvement and management of surface water and groundwater. The Catchment dataset is built on clusters of subcatchments (derived from river waterbody polygons). All Catchments are represented as polygons. No RWB polygons, or SubCatchment polygons, will cross the boundaries of each Catchment feature. All RWBs will be completely nested within a single Catchment polygon.

The Catchment dataset forms part of a three tier hierarchy. The base unit and tier 1 are the WFD River waterbody (RWB) basins. The middle tier will consist of the WFD SubCatchments. And final tier 3 layer will be the WFD Catchments.


National coverage in Republic of Ireland. Catchment ID is a unique identifier for each Catchment unit.
