PLC Assessment data river catchments
The dataset reflects the spatial delineation of river catchments in the Baltic Sea drainage area. The data is based on the reporting by Contracting Parties within in the HELCOM Pollution Load Compilation (PLC) framework. The catchments consist of monitored river catchments and unmonitored coastal areas. The delineation of the catchments can be connected to the flow and nitrogen and phosphorous load information available in the PLC assessment data set ( https://metadata.helcom.fi/geonetwork/srv/eng/catalog.search#/metadata/441f878f-67e7-4aa8-927e-8f5e073dc893).
The river catchments consist of whole rivers, meaning that although a river would run through several countries or would be a border river between two countries, the catchment is not split into separate sub-catchments. The unmonitored areas are aggregated based on PLC subbasins and country areas, thus forming areas such as the unmonitored area of Finnish Gulf of Finland, Polish Baltic Proper or Danish Kattegat.
Attribute information:
SourceCode: Unique code for river catchment
Name: Name of river catchment
SubBasin: The PLC subbasin where the river meets the sea.
Country: The Country on which territory the river mouth is located, for border rivers both are mentioned.
Monitoring: The monitoring status of the river (M=monitored and U=unmonitored). Marked as monitored only if it’s been monitored for the whole time series.
Transbound: Listing all countries that have the rivers drainage area on its territory.
Area_km2: The total area of the catchment in square kilometers.
flow_1995...flow_2022: The water flow of the river catchment for the whole time-series
TN_1995...TN_2022: Total nitrogen load of the river catchment for the whole time-series
TP_1995...TP_2022: Total phosphorus load of the river catchment for the whole time-series

- Statement
-
The river catchments are formed from original sub-catchments reported by Contracting Parties in the PLC framework. The editing tasks carried out for the original data set:
- For transboundary rivers all sub-catchments are merged to form complete river catchments, irrespective of territory.
- The sub-catchments that a full time series is not available in the BSEFS assessment data set, are merged to the unmonitored areas.
- For the unmonitored areas that are delineated separately (riverwise unmonitored areas) from the aggregated unmonitored areas are merged with the monitored part of the river.
- Data set is cleaned from holes within catchments (enclave polygons) resulting from the merging unmatching adjacent catchments.
