Water Body Status Classification Arun and Western Streams

Water body status classification data indicates the quality or status of water bodies across a range of different parameters known as quality elements. This dataset includes the classification history of all water bodies in the Arun and Western Streams catchment. Data may be flagged as 'Cycle 1' if the classification uses the rules initiated in 2009 when the first cycle of river basin planning began. These data end in 2015. Or the data may be flagged as 'Cycle 2' if the classification uses the latest rules used in the updated river basin plans. These data begin in 2013 and will end in 2021. For surface water bodies status classification is grouped into ecological and chemical status and for groundwater bodies they are grouped into chemical and quantitative status. This data supports the Water Framework Directive river basin management plans that can be found here: https://www.gov.uk/government/collections/river-basin-management-plans-2015 and is available to view interactively here: http://environment.data.gov.uk/catchment-planning/ManagementCatchment/3004 Attribution statement: © Environment Agency copyright and/or database right 2016.

水体状态分类数据揭示了不同参数所表征的水体质量或状态，这些参数统称为质量要素。本数据集涵盖了阿伦河和西部溪流域内所有水体的分类历史。若分类采用2009年启动的第一轮流域规划所制定的规定，则数据可能被标记为'周期1'。此类数据截止于2015年。或者，若分类采用最新修订的流域规划中所使用的规则，则数据可能被标记为'周期2'，此类数据始于2013年，并将持续至2021年。对于地表水体状态分类，按生态和化学状态分组；对于地下水体，则按化学和定量状态分组。这些数据支持《水框架指令》下的流域管理计划，可在此处查阅：https://www.gov.uk/government/collections/river-basin-management-plans-2015，并可在此处交互式查看：http://environment.data.gov.uk/catchment-planning/ManagementCatchment/3004。归属声明：© 环境署版权和/或数据库权利2016。版权所有。
