Water Framework Directive (WFD) River Basin Districts Cycle 1 is a spatial (polygon) dataset containing attributes that have been collated as defined for the implementation of the Water Framework Directive (WFD). Article 2, clause 2 of the WFD defines them as '...the area of land and sea, made up of one or more neighbouring river basins together with their associated ground waters and coastal waters'.

Mae Ardaloedd Basn Afon y Gyfarwyddeb Fframwaith Dŵr (WFD) ar gyfer Cylch 1 yn cynnwys nodweddion sydd wedi cael eu coladu fel y diffiniwyd ar gyfer gweithredu'r Gyfarwyddeb Fframwaith Dŵr. Mae erthygl 2, cymal 2 y WFD yn eu diffinio fel 'ardal o dir a môr, sy'n cynnwys un neu fwy o fasnau afon cyfagos ynghyd â'r dyfroedd daear ac arfordirol cysylltiedig'. Mae'r set ddata hon yn cwmpasu'r haen ar gyfer Cylch 1 y Gyfarwyddeb Fframwaith Dŵr. Datganiad priodoli Yn cynnwys gwybodaeth Cyfoeth Naturiol Cymru Cyfoeth Naturiol Cymru a Chronfa Ddata Hawl. Cedwir pob hawl. Rhai nodweddion o'r wybodaeth hon yn seiliedig ar ddata gofodol digidol a drwyddedwyd oddi wrth y Ganolfan Ecoleg a Hydroleg NERC (CEH). Yn cynnwys data Arolwg Ordnans Hawlfraint y Goron a hawl cronfa ddata 2015.

Lineage

River Basin Districts have been delineated by using River Catchments as 'building blocks' that have been aggregated together within a GIS, ensuring that WFD rivers do not intersect boundaries. Coastal and transitional waterbodies are also merged and assigned to a river basin district. River Catchments were delineated through use of flow data and a digital terrain model run through a hydrological model.
