The WAP distinguishes between warnings, information and search reports.
The International Main Alert Centres (IHWZ) issue warnings in cases of water pollution incidents implying substances noxious to water, if the amounts or concentrations concerned may detrimentally impact the…
The ICPR has decided to derive environmental quality standards for the Rhine according to the rules of Annex V, Paragraph 1.2.6 of the Water Framework Directive (WFD) for the list of substances relevant for the Rhine. As far as possible, these EQS Rhine are to be based on the…
The relevant substances to consider in the international river basin district Rhine for the programme “<link _blank>Rhine 2020” and the<link _blank> 2nd Management Plan Rhine 2015 are set. For these substances, the emission inventory at hand relating to the year 2010 has been carried out. Due to the…
The synthesis report at hand represents the results of the biological inventories within the second monitoring cycle (2012/2013) of the management plan for the international river basin district Rhine and compares them with the results of the first cycle in 2006/2007. The data on…
The objective of the Warning and Alarm Plan (WAP) is, to pass on reports on sudden pollutions with substances noxious to water in the Rhine catchment if the amount and concentration may detrimentally impact the water quality and/or biocoenosis of the Rhine and to warn the…
Based on the report on the “Evidence of the effectiveness of measures aimed at reducing flood levels of the Rhine” (ICPR report no. 199, 2012) the ICPR has calculated the modified flood probability resulting from flood retention measures already implemented or planned (ICPR…
The species composition, abundance and age structure of fish reflect the large-scale occurrence of habitat structures of importance for different life stages and the river continuity. Discharge modifications (impoundments, water intake, diversion) and thermal pollution also…
The species diversity and dominant species proportions of the macrozoobenthos (invertebrates living on the river bottom) is an indicator of water quality, and of the quantity and quality of habitat structures in a water body. All in all, more than 500 macrozoobenthos species were…
Diatoms are microscopic small single-celled algae. Due to their great species diversity, their widespread occurrence and their sensitivity concerning the physical-chemical characteristics of their habitat they are excellent bio-indicators. During 2012/2013, 306 species of benthic…
