WFD River Waterbody Catchments Cycle 1

The 'WFD River Water body Catchments Cycle 1' dataset is a polygon Shapefile defined for the implementation of the Water Framework Directive. Catchments are defined as an area of land from which all surface run-off flows through a series of streams, rivers and, possibly, lakes to a particular point in the water course such as a river confluence.
Water bodies are attributed with a unique identifier ‘EA_WB_ID' (equivalent to WB_ID in Cycle 2) so this dataset can be linked directly to other WFD data sources such as river water body catchment, physical characteristics, risk, classification and proposed objectives as well as Cycle 2 datasets. NB Not all catchments have a designated WFD river water body within them.
This dataset was previously known as WFD River Waterbody Catchments.
This dataset covers the layer for Cycle 1 of the Water Framework Directive. The equivalent layer for Cycle 2 is covered under WFD River Water body Catchments Cycle 2

《WFD 河流水体流域循环第1版》数据集系为水框架指令的实施而定义的多边形 Shapefile。流域被界定为一片陆地，其地表径流通过一系列溪流、河流，以及可能包含湖泊，最终汇聚至水系中的特定点，如河流交汇处。水体被赋予唯一标识符‘EA_WB_ID’（相当于第2版的 WB_ID），以便该数据集能够直接与其他水框架指令数据源相连接，包括河流水体流域、物理特征、风险、分类以及拟定的目标，以及第2版数据集。请注意，并非所有流域内部均设有指定的水框架指令河流水体。此数据集先前被称为WFD河流水体流域。该数据集涵盖了水框架指令第1版的图层，而第2版的等价值图层则涵盖在《WFD河流水体流域循环第2版》中。请注意，环境署不再提供威尔士的水体数据，此类数据现可通过自然资源威尔士获取。归属声明：包含环境署信息©环境署及/或数据库权利2017。包含测量局数据©英王版权及数据库权利2013。基于从生态与水文中心许可的数字空间数据，©自然环境研究委员会（NERC）(CEH)。
