Restoration of the ecological continuity for fish, macroinvertebrates, sediments and terrestrial animals by any transversal structure, through complete or partial removal of that structure, or by adding a fish pass if the previous options are not feasible.

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

Evaluation of the quality element "hydrological regime" per surface water body

The WFD's (2000/60/CE) quantitative status objectives aim to ensure a balance between groundwater withdrawal and recharge.

The chemical status of the groundwater bodies is assessed as being good or failing to achieve good chemical status. The assessment of the chemical status for the third river basin management plan is based on the list of substances of directive 2008/105/EC as well as its environmental quality standards.

The evaluation of the groundwater bodies is based on the quantitative and the chemical status. The groundwater bodies can be classified as good or as bad.

Restoration of a balanced, near-natural water balance in the entire catchment area of a surface water body. Near-natural urban water management, through measures for retention, infiltration and evaporation before the discharge of precipitation water.

Restoration of near-natural flow regime at hydropower plants, discharges and diversions. Adapted operation of hydropower plants, verification and, if necessary, restoration of the natural state of discharge points and verification and possible elimination of water abstractions by means of specific studies of alternative solutions and proposals for mitigation measures.
