Water Framework Directive (WFD) River Waterbodies (RWB) are the management and reporting units for the WFD. The RWB polygons are associated watershed areas delineated using ArcHydro and the EPA 20m hydrologically corrected DTM. Each RWB polygon is attributed with a unique identifier (EU_CD) which is common to the RWB lines. This dataset can be linked directly to other WFD data sources such as physical characteristics, risk, classification and other objectives.
