WFD Operational 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.
