Water Framework Directive (WFD) Transitional (Estuarine) Waterbodies Cycle 1 (2008-2013) is a polygon dataset containing attributes that have been collated as defined for the implementation of the Water Framework Directive (WFD). Article 2, clause 6 of the WFD defines them as '...bodies of surface water in the vicinity of river mouths which are partly saline in character as a result of their proximity to coastal waters but are substantially influenced by freshwater flows'. Transitional waterbodies were defined from Mean High Water.
