Relative change in minimum river flow for a) 2020s, b) 2050s and c) 2080s compared to 1961-1990 for SRES A1B scenario.

Projected change in river floods with a return period of 100 years

20 Nov 2012

Projected change in the level of a 100-year maximum level of river discharge between the reference period 1961–1990 and the 2020s (left), 2050s (centre) and 2050s (right) based on an ensemble of 12 RCM simulations with LISFLOOD for the SRES A1B scenario.

Trend in median total ammonium, total phosphorus and nitrate concentration of river water bodies, grouped by ecological status/potential class

16 Nov 2012

Concentrations are expressed as a median of annual mean concentrations. Up to three-year gaps of missing values have been interpolated or extrapolated. Only complete series with no missing values after this interpolation/extrapolation are included. The number of time series/river stations is shown in parentheses. The trend for 1992 to 2010 for each of the ecological quality classes has been linearly extended to 2027 — or when the concentration level becomes negative.
