The table below gives information on all the current columns
of data retrieved by the different get_... functions of
cde; names, what they mean and which functions return them.
The EA do modify the format of their data from time to time, so this
will be updated as necessary.
| Column name | Description | Output from which functions |
|---|---|---|
| river_basin_district | Name of the River Basin District. This is the top level in the catchment hierarchy. | All get_… functions |
| management_catchment | Name of the Management Catchment, the next level down the hierarchy, see link above. | All get_… functions |
| operational_catchment | name of the Operational Catchment, the next level down from Management Catchments. | All get_… functions |
| waterbody_id | Waterbodies are the smallest unit in the catchment hierarchy, representing all or part of a river system, lake, estuary etc. Each has a unique ID (WBID). | All get_… functions |
| status | WFD status classification (High, Good, Moderate, Poor or Bad). For objectives this represents the target (aimed for) status class. | All get_… functions except get_pa |
| classification_item | Broad category of classification level (ecological, chemical or quantitative). | get_objectives, get_rnag & get_status |
| classification_level | The level within the range of classification elements that the status class refers to (see details here). | get_objectives, get_rnag & get_status |
| cycle | Which cycle of assessment the data come from. The first cycle. The
first cycle ran from 2009 to 2015 and cycle 2 to 2015-2021. There were
changes in some environmental standards between cycles and for a two
year period (2013-2014) where both assessment methods were employed,
cde only returns cycle 2 assessments. |
