This record is for Approval for Access product AfA433. WFD Management Catchments Cycle 2 is a polygon Shapefile dataset collated as defined for the implementation of the Water Framework Directive (WFD). Management catchments are the unit of geography for which action plans are drafted in implementing the WFD. 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. Transitional and coastal waters were also combined into areas representing managment 'catchments' for coastal areas.This process was conducted by using expert judgement in consultation. WFD Management Catchments have an action plan published that relates to all waterbodies that fall within its boundaries. These data apply to Cycle 2 of the Water Framework Directive. The equivalent layer for Cycle 1 is covered by AfA092. Attribution statement: © Environment Agency copyright and/or database right 2014. All rights reserved.
