According to the water framework directive (Directive 2000/60/CE), the biological parameter fish are monitored in surface water bodies in order to determine the ecological status. Fish react sensitively to the continuity and the hydrological flow of surface water. Fish are therefor sampled in the SWB which have deficits here. The methodology applied for sampling is the standard NF EN 14962:2006 "water quality − guidance on the scope and selection of fish sampling methods".

According to the Water Framework Directive (Directive 2000/60/EC ), macrophytes and diatoms are monitored as two sub-elements of the aquatic flora. Macrophytes are particularly sensitive to organic pollution, trophy and hydromorphology. The diatom assemblages are different in function of concentrations of nutrients and organic pollutants.

Overall evaluation of the hydromorphological status per surface water body. The assessment of the hydromorphological status is based on the mapping and the assessment of the structural quality of the Luxembourgish watercourses. The quality element “morphology” has not been covered in the framework of the structural quality mapping, but only the two quality elements related to continuity and morphology. The hydromorphological status is assessed in 5 classes.

The hydromorphological status was determined by a monitoring compliant with the Water Framework Directive (Directive 2000/60/EU). The elaboration of a structural quality mapping is one part of this monitoring. Within the scope of the work on the structural quality mapping, a total of 31 parameters in the area of the river bed, the river bank and the floodplain are assessed so that the structural quality mapping contains detailed information on the river morphology and the river continuity. In this case, the evaluation of the mapped sections is based on seven classes. The results of the evaluation were aggregated into an overall evaluation per mapped section.

This dataset was reported by the Grand Duchy of Luxembourg under the following obligation: "Water Framework Directive - River Basin Management Plans - 2016 Reporting". For operational purposes, the following obligations are part on the 2016 WFD RBMP reporting process: - "Water Framework Directive - River Basin Management Plans - 2016 Spatial data" - "Water Framework Directive - River Basin Management Plans - 2016 RBDSUCA XML data" - "Water Framework Directive - River Basin Management Plans - 2016 RBD XML data" This reporting obligation is an Eionet core data flow This dataset is one element of these.

According to the WFD (Water framework directive) the assessment of the stauts of the surface water bodies is based on the evaluation of the monitoring results. According to Article 8 of the WFD, Member States must ensure the establishment of monitoring programs, inter alia, for surface waters. The monitoring of the surface water bodies is carried out at surveillance monitoring stations and operational measuring points. For surface waters, the WFD also foresees an investigative monitoring.
