Work due 01 Jan 2014
This indicator could be improved as more countries implement the EIONET-water data flow on the basis of the monitoring networks to be established under the WFD. There are gaps in river characteristic information from some countries. This does not enable the stratification of all stations by river size, and thus limits to some extent the current dataset for size-stratification. Also many countries did not report all the requested summary statistics such as the median. A bigger gap in the information is in terms of catchment pressures. Some countries have used Corine land cover data to provide proxy indicators of pressures. It is expected that this aspect will improve significantly during the next year as new updated Corine data will be available, and as work is undertaken by the ETC/WTR and ETC/TE to fill in the gaps in the pressure indicators. More times series data would improve the dataset particular from Southern countries.
More data in terms of time series (esp. from southern countries)
