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 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).

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.

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.

Riverbed improvement by permanent removal of heavy stabilization techniques or by their replacement with more natural techniques, in order to recreate a riverbed composed of natural substrate with a low flow channel, a variation of depths and a diversity of flow rates, thus creating microhabitats for aquatic flora and fauna.

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

Preservation of a corridor for a dynamic river development, where the land is ever not – or extensively used, whose width is compliant with the river typology, which ensures a lateral connection to the alluvial plain, thus creating diversified aquatic and terrestrial habitats.
