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

  • 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.

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

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

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.

  • 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 elements which have been covered in the framework of the structural quality mapping are: morphology, continuity and hydrological regime. The hydromorphological status is assessed in 5 classes. It is a “pessimistic assessment” because only the worst of the three parameters morphology, continuity and hydrological regime is retained.

  • Evaluation of the quality element "morphological conditions" per surface water body

  • Evaluation of the quality element "continuity" per surface water body
