- Abstract
- This is a spatial dataset identifying the river waterbodies managed under the Water Framework Directive and any related programs. 'WFD River Waterbodies Cycle 2' is a subset extracted from the NRWs Detailed River Network. Other input datasets and extensive local Natural Resources Wales staff knowledge has been used to augment the core geometry to incorporate critical spatial detail and attribution, such as flow direction and path, not available from the OS mapping and to verify the accuracy of the centreline itself. Sections of DRN belonging to a particular waterbody have been merged together so that a defined waterbody is a single record within the dataset (rather than being made up of hundreds of records within the DRN). DRN attributes become obsolete at this point and waterbody specific attribution has been added. Therefore the geometry for the resulting waterbodies is taken from the DRN, but the attribution and number of records is very different. Not all sections of the DRN belong to defined waterbodies and the final WFD river waterbody dataset represents <20% of the online DRN. Information Warning Anomalous results were observed at freshwater sampling points throughout Wales for orthophosphate between January 2014 and December 2016. This data was used as part of the 3-year data set which informed the 2015 WFD classification and affected the outcome of that exercise.
