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

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 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.

The chemical status of the surface water 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 and the environmental quality standards established by the new directive 2013/39/EC.

The chemical status of the surface water 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 and the environmental quality standards established by the new directive 2013/39/EC. The assessment without the ubiquist substances permits to get a differentiated picture of the actual situation.

Phytoplancon is one of the 4 biological quality elements (BQE) used for the assessment of the ecological status of the surface water bodies. The assessment is made in 5 classes : high (blue) - good (green) - moderate (yellow) - poor (orange) - bad (red). The evaluation of this BQE is only relevant for the large rivers where the quantity of phytoplancton is significant and can be evaluated. Therefore phytoplancton is assessed in natural water bodies of type VI an in heavy modified waterbodies (HMWB) presenting a lake character, as the HMWB Sûre (WB III-2.2.1) and the HMWB Our (WB V-1.2). The frequency for phytoplancton monitoring is annually with 6 samples between April and October.

Macrophytes and phytobenthos (diatoms) are two sub-elements of the biological quality element (BQE) of the aquatic flora used for the assessment of the ecological status/potential. The assessment of the aquatic flora is made in 5 classes : high (blue) - good (green) - moderate (yellow) - poor (orange) - bad (red). The aquatic flora ist assessed following the sub-element the less good (worst-case).

Phythobenthos (Diatoms) are a sub-element of the biological quality element (BQE) of the aquatic flora used for the assessment of the ecological status/potential. The assessment is made in 5 classes : high (blue) - good (green) - moderate (yellow) - poor (orange) - bad (red). The diatom assemblages are different in function of concentrations of nutrients and organic pollutants.
