Water Framework Directive (WFD) Management Catchments Cycle 1 is a spatial (polygon) dataset collated as defined for the implementation of the WFD) Management catchments are the unit of geography for which action plans are drafted in implementing the WFD. WFD Management Catchments have an action plan published that relates to all waterbodies that fall within its boundaries.

Mae Dalgylchoedd Gweithredol y Gyfarwyddeb Fframwaith Dŵr (WFD) ar gyfer Cylch 1 yn set ddata ofodol (polygon) sydd wedi'i chasglu fel y diffiniwyd ar gyfer gweithredu'r WFD. Dalgylchoedd gweithredol yw'r uned ddaearyddol y dylunnir cynlluniau gweithredu ar eu cyfer wrth weithredu'r WFD. Mae Dalgylchoedd Gweithredol y WFD wedi cyhoeddi cynllun gweithredu sy'n ymwneud phob corff dŵr sydd yn eu cyffiniau. Mae'r set ddata hon yn cynnwys yr haen ar gyfer Cylch 1 y Gyfarwyddeb Fframwaith Dŵr.

Lineage

WFD Management Catchments have been delineated by using WFD River Waterbody Catchments [these were delineated through use of flow data and a digital terrain model run through a hydrological model] as "building blocks" that have been aggregated together within a GIS ensuring that WFD rivers do not intersect boundaries. This process was conducted by using expert judgement in consultation.
