Water quality - Guidance standard on determining the degree of modification of river hydromorphology
This European Standard provides guidance on characterizing the modifications of river hydromorphological features described in EN 14614. Both standards focus more on morphology than on hydrology and continuity, and on lateral and longitudinal continuity rather than on vertical continuity which is difficult to measure. This standard will enable consistent comparisons of hydromorphology between rivers within a country and between different countries in Europe, providing a method for broad based characterization across a wide spectrum of hydromorphological modification of river channels, banks, riparian zones and floodplains. Its primary aim is to assess "departure from naturalness" as a result of human pressures on river hydromorphology, and it suggests suitable sources of information (see Table A.1) which may contribute to characterizing the modification of hydromorphological features.
In doing so, it does not replace methods that have been developed for local assessment and reporting. Decisions on river management for individual reaches or catchments require expert local knowledge and vary according to river type.
Wasserbeschaffenheit - Anleitung zur Beurteilung von Veränderungen der hydromorphologischen Eigenschaften von Fließgewässern
Diese Europäische Norm gibt eine Anleitung zur Beurteilung von Veränderungen der in EN 14614 beschriebe¬nen hydromorphologischen Eigenschaften von Fließgewässern. Beide Normen fokussieren mehr auf die Gewässerstrukturbeschaffenheit als auf Hydrologie und Durchgängigkeit. Die Konzentration liegt stärker auf der lateralen und longitudinalen Verbindung als auf der vertikalen Kontinuität, die sehr schwer zu erfassen ist. Diese Norm ermöglicht konsistente Vergleiche der Hydromorphologie zwischen den Fließgewässern eines Landes sowie zwischen denen verschiedener Länder in Europa, indem sie eine Methodik zur allgemeinen Beschreibung eines breiten Spektrums hydromorphologischer Veränderungen von Gewässerlauf, Ufern, Uferzonen und Überschwemmungsgebiete bietet. Vorrangiges Ziel ist eine Einschätzung der „Abweichung von der potentiell natürlichen Beschaffenheit“ als Resultat der Beeinträchtigung der Hydromorphologie von Fließgewässern durch den Menschen. Es werden geeignete Informationsquellen (siehe Tabelle A.1) genannt, die bei der Beschreibung von Veränderungen hydromorphologischer Eigenschaften hilfreich sein können.
Durch diese Vorgehensweise werden keine Verfahren ersetzt, die für eine Vorortaufnahme und bewertung entwickelt wurden. Entscheidungen über die Bewirtschaftung bestimmter Gewässerabschnitte oder Teileinzugsgebiete erfordern spezielle Ortskenntnisse und unterscheiden sich in Abhängigkeit vom Fließgewässertyp.
Qualité de l'eau - Guide pour la détermination du degré de modification de l'hydromorphologie des rivières
La présente Norme européenne fournit des recommandations pour évaluer les modifications des caractéristiques hydromorphologiques des rivières décrites dans l'EN 14614. La norme permet une caractérisation généralisée et cohérente sur tout un large spectre de modifications hydromorphologiques affectant les chenaux des rivières, les berges, les zones riveraines et les plaines d'inondation. Elle a pour objectif principal d'évaluer « l'écart au naturel » dû aux pressions humaines exercées sur l'hydromorphologie des rivières et suggère des sources adéquates d'informations qui peuvent contribuer à décrire la modification des caractéristiques hydromorphologiques. Ce faisant, elle ne remplace pas les méthodes qui ont été mises au point pour l'évaluation locale et le rapportage. Les décisions relatives à la gestion de rivières pour des tronçons ou bassins-versants individuels exigent des connaissances locales d'expert et varient en fonction du type de rivière.
Kakovost vode - Smerni standard za določanje stopnje spreminjanja hidromorfoloških značilnosti vodotokov
Ta evropski standard zagotavlja vodilo za karakterizacijo spreminjanja hidromorfoloških značilnosti vodotokov, opisanih v EN 14614. Oba standarda se bolj osredotočata na morfologijo kot hidrologijo in kontinuiteto ter na lateralno in longitudinalno kontinuiteto in ne na vertikalno kontinuiteto, ki jo je težko meriti. Ta standard bo omogočil konsistentno primerjavo hidromorfoloških značilnosti med vodotoki v državi in med različnimi državami v Evropi, saj prepisuje metodo široko zasnovane karakterizacije na širokem spektru spreminjanja hidromorfoloških značilnosti rečnih kanalov, bregov obrežnih pasov in naplavnih ravnic. Njegov temeljni cilj je ocenjevanje »odklona od naravnosti«, ki je posledica človeških pritiskov na hidromorfološke značilnosti vodotokov, hkrati pa omenja primerne vire informacij (glej Preglednico A.1), ki lahko prispevajo h karakterizaciji spreminjanja hidromorfoloških značilnosti. Pri tem ne nadomešča metod, ki so bile razvite za lokalno ocenjevanje in poročanje. Odločitve o upravljanju vodotokov za posamezne dele rek med dvema zavojema ali rezervoarje zahtevajo lokalno strokovno znanje in se razlikujejo v skladu z vrsto reke.

According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.
Guidance standard for assessing the hydromorphological features of rivers describes a protocol for field survey and feature recording, whereas this standard gives guidance on assessing the modification of river hydromorphological features. It focuses especially on human pressures that affect rivers; thus, it may be helpful for implementing the WFD by indicating the extent to which these pressures might have caused a departure from hydromorphological reference conditions. Although the procedure described in this standard enables the hydromorphological characterization of rivers, it does not attempt either to describe methods for defining high status for hydromorphology under the WFD or to link broadscale hydromorphological classification to assessments of ecological status. In addition to its relevance to the WFD, this standard has applications also for nature conservation, environmental impact assessment, river basin management, flood risk assessment (e.g. the EC Floods Directive) and setting targets for river restoration work.
