This layer contains the inspections and controls carried out by the SICOPOL service of the Water Management Administration.

Status of the authorization demands.

This layer contains the distances to hydrological monitoring stations for which authorisations must first be clarified with the Service Hydrologie (red) or for which the latter must at least be informed (orange and yellow).

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.

Riverbanks improvement by permanent removal of heavy stabilization techniques or by their replacement with plant engineering solutions, in order to recreate near-natural riverbanks with typical vegetation and diversified structures, thus creating microhabitats for aquatic flora and fauna.

Riverbed diversification through natural substrate supply and/or through the incorporation of structural elements such as stones, rocks, stumps or trunks, in order to recreate a nature-like structure and composition of the bed load, with a low flow channel, a variability of depths and a diversity of flow rates, thus creating microhabitats for the aquatic flora and fauna.

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.

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.

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.

Restoration of a near-natural water and sediment balance. Near-natural flow conditions (in particular an ecological minimum flow) at individual structures such as transversal structures, impoundment areas or diversions, by removing or reconstructing transversal structures, removal or shortening backwater areas or abandoning or reducing diversions.
