WFD Cycle 1 Site Classifications 2013

For the Water Framework Directive (WFD) water bodies are given classifications based on data collected at monitoring sites. There may be one or more sites per water body. Classification is an important part of the WFD life cycle, it allows the current environmental conditions to be defined. Subsequent classifications indicate if any work carried out is having a positive effect.
Data are collected by field operatives or automated collection methods. These data are passed through models that calculate the classification for a site. These results then form the basis of a water body classification.
Included are much of the supporting data produced by the models, called classification facts.
This data set is extracted from the Environment Agency's Catchment Planning System. Data are available for each year and WFD planning cycle.

针对《水框架指令》（WFD），水体根据在监测站点收集的数据被赋予相应的分类。每个水体可能包含一个或多个监测站点。分类是《水框架指令》生命周期中的重要环节，它能够定义当前的环境状况。后续的分类可以指示所进行的工作是否产生了积极的影响。数据由现场操作人员或自动化收集方法收集。这些数据经过模型处理，以计算每个站点的分类。这些结果构成了水体分类的基础。此外，还包括由模型产生的许多辅助数据，称为分类事实。该数据集来源于环境署的流域规划系统。数据每年和《水框架指令》规划周期均可用。数据附带的可读文件中提供了更多信息。版权声明：环境署版权和/或数据库权利，2016年。版权所有。” }
