The types of measures related to hydromorphology (HY) which are defined in the catalogue of measures of the third river basin management plan, were assigned to the individual water bodies. The objective of this assignation is to identify for each water body those measures that will help to reduce the pressures and deficits present in the water body, thereby improving its status or maintaining its good status. The hydromorphological measures include the restoration of the ecological continuity, the improvement of the riverbed structure as well as the restoration of a near-natural hydrological regime.

Typical river restoration technique. Re-meandering and restoration of the riverbed in order to recreate a new meandering course compliant with the river typology, with a riverbed and riverbanks rich in structures.

Restoration of the ecological continuity for fish, macroinvertebrates, sediments and terrestrial animals by culverts, through its permanent suppression, or through its adaptation in order to reach natural conditions of substrate, depth, flow rate, luminosity and riverbank structure.

Macrophytes 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). Macrophytes are particularly sensitive to organic pollution, trophy and hydromorphology.

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.

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.

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).

Fish are 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). Fish are sensitive to the hydromorphology, water quality, biological continuity and water regime.
