The Water Framework Directive (WFD) River Waterbody Catchments Cycle 2 are a spatial dataset collated as defined for the implementation of the Water Framework Directive. Catchments are defined as an area of land from which all surface run-off flows through a series of streams, rivers and, possibly, lakes to a particular point in the water course such as a river confluence. Since rivers are attributed with a unique identifier 'EA_WB_ID' this dataset can be linked directly to the WFD river waterbody to which it relates.
