  • 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.

  • Cartography of cross profiles of a representative river section every 1000 meters. The assessment of the rate of river incision was calculated from the ratio between bankfull height and bankfull width.

  • 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 five classes. The areas river bed, left river bank, right riverbank, left floodplain and right floodplain are represented in 5 strips.

  • Detailed inventory of crossing structures which represent an obstacle to the ecological continuity for fish or sediments (e.g. culverts).

  • Detailed inventory of transversal structures which represent an obstacle to the ecological continuity for fish or sediments (e.g. weirs, dams, ramps, waterfalls).

  • Detailed cartography of substrate based on the analysis of 100 meters representative river sections, every 1000 meters.

  • River basin specific pollutants are substances that enter the river basin or parts of it in significant quantities. The quantitative assessment is done with environmental quality standards that are fixed by the European Union member states. In Luxembourg, the substances and limit values (annual average) are fixed in the grand ducal regulation of 15 January 2016 (règlement grand-ducal du 15 janvier 2016 concernant l'évaluation des masses d'eau de surface). Evaluation takes place with 2 categories (good, moderate and worse). River basin specific pollutants are used together with the general physico-chemical parameters for evaluation of the ecological status.

  • This layer contains the distances to hydrological monitoring stations for which authorisations must first be clarified with the Service Hydrologie (red) or for which the latter must at least be informed (orange and yellow).

  • Enable an autonomous dynamic development of the river within clearly defined zones (ideally within a river corridor), leading to the formation of riverbed and riverbanks’ structures compliant with the river typology.
