HVD - Annex 2 Earth Observation and Environment - Water - WFD monitoring network GWB (2015-2021)

Network of measurement stations for the period from 2015 to 2020, established as part of the surface water quality monitoring program in accordance with the Water Framework Directive (2000/60/EC). The measurement network includes two components: the surveillance control network and the operational control network. The results of this monitoring program (2015-2020) were used for assessing the state of surface water bodies within the framework of the 3rd management plan. Physico-chemical parameters as well as chemical parameters are sampled at the same station. The location of biological parameter measurement stations may vary slightly.

According to the water framework directive WFD(DIR 2000/60/CE), important physico chemical parameters are measured in the surface water bodies for the assessment of the ecological status. The modalities for this monitoring are stated in the grand ducal Regulation of 30 December 2010 (règlement grand-ducal you 30 décembre 2010 concernant l 'évaluation of the dimension d' eau de surface).

With regard to the implementation of the Water Framework Directive, specific types of watercourses have been designated for Luxembourg. As in the context of various works the German stream types (LAWA types) are used, these have also been assigned to the Luxembourgish surface water bodies

The surface water typology was determined on the basis of geographical , geological, morphological and hydrological characteristics. The Luxembourgish surface water typology comprises six types. For all six types the reference conditions, which would be achieved if there were no anthropogenic pressures impacting surface waters, are described in fact sheets. The reference conditions correspond to the high status of surface water bodies.
