Projected change in average annual and seasonal river flow
-
Projected change in mean annual and seasonal river flow between the climate change scenario (SRES A1B, 2071-2100) and the control period (1961-1990). Simulations with LISFLOOD based on an ensemble of 11 RCMs.

Nitrate concentrations in rivers between 1992 and 2010 in different sea regions of Europe.
-
The sea region data series are calculated as the average of annual mean data from river monitoring stations in each sea region. The data thus represents rivers or river basins draining into that particular sea. Only complete series after inter/extrapolation are included (see indicator specification). The number of river monitoring stations included per sea region is given in parentheses.

BOD5 concentrations in rivers between 1992 and 2010 in different geographical regions of Europe
-
The data series per region are calculated as the average of the annual mean for river monitoring stations in the region. Only complete series after inter/extrapolation are included (see indicator specification). The number of river monitoring stations included per geographical region is given in parentheses. BOD7 data has been recalculated into BOD5 data.

Phosphorus concentrations in rivers (orthophosphate) between 1992 and 2010 in different sea regions of Europe
-
The sea region data series are calculated as the average of annual mean data from river monitoring stations in each sea region. The data thus represents rivers or river basins draining into that particular sea. Only complete series after inter/extrapolation are included (see indicator specification). The number of river monitoring stations per sea region is given in parentheses.

The sea region data series are calculated as the average of annual mean data from river monitoring stations in each sea region. The data thus represents rivers or river basins draining into that particular sea. Only complete series after inter/extrapolation are included (see indicator specification). Two regions are not shown in the figure due to a lack of data (Barents Sea: 1 station, Norwegian Sea: 2 stations); these stations have NO3 concentrations below 0.8 mg/l N.

Biochemical Oxygen Demand (BOD5) and total ammonium concentrations in rivers between 1992 and 2010
-
Concentrations are expressed as annual mean concentrations. Only complete series after inter/extrapolation are included (see indicator specification). The number of river monitoring stations included per country is given in metadata (see downloads and more info). BOD7 data has been recalculated into BOD5 data.
