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.

Mae’r Gyfarwyddeb Fframwaith Dŵr Cyrff Dŵr (aberol) Trosiannol yn set ddata gofodol sy'n cynnwys priodoleddau a gasglwyd fel y diffiniwyd ar gyfer gweithredu’r Gyfarwyddeb Fframwaith Dŵr (WFD). Mae Erthygl 2, cymal 6 y Gyfarwyddeb Fframwaith Dŵr yn eu diffinio fel '... cyrff o dŵr wyneb yng nghyffiniau aberoedd afonydd sy'n rhannol hallt o ganlyniad i'w hagosrwydd i ddyfroedd arfordirol ond sydd hefyd dan ddylanwad sylweddol dŵr croyw sy’n llifo'. Diffiniwyd cyrff dŵr Trosiannol o ffiniau penllanw cymedrig, a gymerwyd yn uniongyrchol o OS 1: 50K MeridianTM 2, a ffiniau aberol a ddiffiniwyd ar gyfer y Gyfarwyddeb Trin Dŵr Gwastraff Trefol (UWWTD). Gan fod cyrff dŵr yn cael eu priodoli â dynodwr unigryw (EA_WB_ID) gellir cysylltu'r set ddata hon yn uniongyrchol â ffynonellau data eraill y Gyfarwyddeb Fframwaith Dŵr megis nodweddion ffisegol, risg, dosbarthiad ac amcanion arfaethedig. Mae'r data hwn yn berthnasol i Gylch 1 y Gyfarwyddeb Fframwaith Dŵr.
