WFD Surface Water Management Catchments Cycle 2

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.

本记录适用于产品 AfA433 的访问批准。WFD 管理流域周期 2 是一个多边形 Shapefile 数据集，该数据集按照《水框架指令》（WFD）的实施要求进行汇编。管理流域是实施 WFD 时制定行动计划的地域单元。WFD 管理流域是通过使用 WFD 河流水域流域（这些流域通过流量数据和通过水文模型运行的数字地形模型进行划界）作为“构建块”，并在地理信息系统（GIS）中汇总而成的，以确保 WFD 河流不与边界相交。过渡区和沿海水域也被合并为表示沿海区域管理“流域”的区域。该过程是通过专家判断并征询意见而进行的。WFD 管理流域已发布行动计划，该计划与位于其边界内的所有水域相关。这些数据适用于《水框架指令》的第二周期。第一周期的等效层由 AfA092 覆盖。归属声明：© 环境署版权和/或数据库权利 2014。版权所有。归属声明：© 环境署版权和/或数据库权利 2014。版权所有。
