Water quality - Guidance standard for assessing the hydromorphological features of rivers
This document is focused on the structural features of rivers, on geomorphological and hydrological processes, and on river continuity. This document is focused on the structural features of rivers, on geomorphological and hydrological processes, and on river continuity. It provides guidance on the features and processes to be taken into account when characterizing and assessing the hydromorphology of rivers. The word ‘river’ is used as a generic term to describe flowing watercourses of all sizes, with the exception of artificial water bodies such as canals. The document is based on methods developed, tested, and compared in Europe, including the pan-European REFORM project (https://reformrivers.eu/). Its main aim is to improve the comparability of hydromorphological assessment methods, data processing and interpretation. It provides broad recommendations for the types of parameters that should be assessed, and the methods for doing this, within a framework that offers the flexibility to plan programmes of work that are affordable. Although this document does not constitute CIS guidance for the WFD, relevant references provided by the CIS expert group on hydromorphology have been included in the Bibliography.
Although it has particular importance for the WFD by providing guidance on assessing hydromorphological quality, this document has considerably wider scope for other applications. 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, while recognizing the important influence of hydromorphology on plant and animal ecology, no attempt is made to provide guidance in this area, but where the biota have an important influence on hydromorphology, these influences are included.
NOTE A case study illustrating the application of this document is given in Gurnell and Grabowski[1].
Wasserbeschaffenheit - Anleitung zur Beurteilung hydromorphologischer Eigenschaften von Fließgewässern
Der Schwerpunkt dieses Dokuments liegt auf den strukturellen Eigenschaften von Flüssen, auf geomorpholo¬gischen und hydrologischen Prozessen sowie auf der Durchgängigkeit von Flüssen. Dieses Dokument gibt eine Anleitung zu den bei der Charakterisierung und Beurteilung der Hydromorphologie von Fließgewässern zu berücksichtigenden Merkmalen und Prozessen. Das Wort „Fluss“ wird als Oberbegriff für fließende Wasserläufe aller Größen verwendet, mit Ausnahme künstlicher Gewässer wie Kanäle. Das Dokument beruht auf Verfahren, die in Europa entwickelt, geprüft und verglichen worden sind, einschließlich des europaweiten REFORM-Projekts (https://reformrivers.eu/). Das Hauptziel dieses Dokuments ist es, die Vergleichbarkeit der hydromorphologischen Beurteilungsmethoden, der Datenverarbeitung und der Interpretation zu verbessern. Es enthält umfassende Empfehlungen für die Arten von Parametern, die bewertet werden sollten, und die Methoden dafür in einem Rahmen, der die Flexibilität bietet, erschwingliche Arbeitsprogramme zu planen. Obwohl dieses Dokument keine CIS-Leitlinien für die WRRL darstellt, wurden relevante Referenzen der CIS-Expertengruppe für Hydromorphologie in die Literaturhinweise aufgenommen.
Obwohl es von besonderer Bedeutung für die WRRL ist, indem eine Anleitung zur Beurteilung der hydromorphologischen Beschaffenheit bereitgestellt wird, hat dieses Dokument einen erheblich größeren Geltungsbereich für andere Anwendungen. Es wird weder versucht, Methoden zur Definition eines hohen Status für die Hydromorphologie im Rahmen der WRRL zu beschreiben, noch eine breit angelegte hydromorphologische Klassifizierung mit Bewertungen des ökologischen Status zu verknüpfen. Obwohl der bedeutende Einfluss der Hydromorphologie auf die Pflanzen- und Tierökologie anerkannt wird, wurde darüber hinaus kein Versuch unternommen, in diesem Bereich eine Anleitung zur Verfügung zu stellen; die wichtigen Einflüsse der Biota auf die Hydromorphologie wurden jedoch einbezogen.
ANMERKUNG Eine Fallstudie, die die Anwendung dieses Dokuments veranschaulicht, ist in GURNELL und GRABOWSKI [1] enthalten.
Qualité de l'eau - Guide pour l'évaluation des caractéristiques hydromorphologiques des rivières
Le présent document se concentre sur les caractéristiques structurelles des rivières, les processus physiques et géomorphologiques, ainsi que sur la continuité de la rivière. Il fournit des recommandations relatives aux caractéristiques et processus à prendre en considération lors d’une caractérisation et d’une évaluation de l’hydromorphologie d’une rivière. Le mot « rivière » est utilisé en tant que terme générique pour décrire les cours d’eau de toutes tailles, à l’exception des plans d’eau artificiels, tels que les canaux. Le présent document se fonde sur les méthodes développées, testées et comparées en Europe, y compris le projet REFORM paneuropéen (https://reformrivers.eu/). Il a pour objectif d’améliorer la comparabilité des méthodes d’évaluation hydromorphologique, du traitement et de l’interprétation des données. Il fournit des recommandations relatives aux types de paramètres qu’il convient d’évaluer ainsi qu’aux méthodes d’évaluation, dans un cadre qui propose suffisamment de flexibilité pour prévoir des programmes de travail qui sont abordables. Bien que le présent document ne constitue pas des recommandations CIS pour la WFD, les références pertinentes fournies par le groupe d’experts CIS concernant l’hydromorphologie ont été incluses dans la Bibliographie.
Bien qu’il soit d’une importance toute particulière pour la WFD du fait qu’il fournisse des recommandations relatives à l’évaluation de la qualité hydromorphologique, le présent document peut également s’appliquer à de nombreux autres domaines. Il n’a pas pour objectif de décrire des méthodes permettant de définir un très bon état pour l’hydromorphologie selon la WFD ni de faire le lien entre la classification hydromorphologique à grande échelle et les évaluations de l’état écologique. En outre, malgré l’influence importante de l’hydromorphologie sur l’écologie végétale et animale, aucune recommandation n’est faite dans le présent document. Cependant, ces influences sont mentionnées dans les cas où les biotes exercent une influence cruciale sur l’hydromorphologie.
NOTE Une étude de cas illustrant l’application du présent document est fournie par Gurnell et Grabowski[1].

Introduction
In the past, many countries in Europe assessed river ‘quality’ simply in terms of water chemistry or
pollution within river channels. A more comprehensive understanding of rivers is needed, however, in
view of global issues such as climate change, to answer pressing ecological questions such as those
arising from the EC Water Framework Directive (WFD), the EC Habitats Directive and EC Floods
Directive, to underpin the International Convention on Biodiversity, or to assess proposed river
engineering work and to evaluate the effectiveness of restoration schemes and other catchment
developments.
River habitats and physical processes have suffered historically from a wide range of human impacts,
especially changes in land use since World War II. In most European countries there is now widespread
agreement among environment and conservation agencies to see modified rivers returned to a more
natural condition. This implies a need to evaluate areas deserving protection and those requiring
restoration, and to encourage sustainable management of river systems throughout Europe.
NOTE In this document, ‘assessment’ is used as a broad term referring to the general description of features
and the pressures affecting them. It is not used to imply the judgement of particular levels of ‘quality’ or ‘value’,
whether related to status under the WFD or more generally.
1 Scope
This document is focused on the structural features of rivers, on geomorphological and hydrological
processes, and on river continuity. It provides guidance on the features and processes to be taken into
account when characterizing and assessing the hydromorphology of rivers. The word ‘river’ is used as a
generic term to describe flowing watercourses of all sizes, with the exception of artificial water bodies
such as canals. The document is based on methods developed, tested, and compared in Europe,
including the pan-European REFORM project (https://reformrivers.eu/). Its main aim is to improve the
comparability of hydromorphological assessment methods, data processing and interpretation. It
provides broad recommendations for the types of parameters that should be assessed, and the methods
for doing this, within a framework that offers the flexibility to plan programmes of work that are
affordable. Although this document does not constitute CIS guidance for the WFD, relevant references
provided by the CIS expert group on hydromorphology have been included in the Bibliography.
Although it has particular importance for the WFD by providing guidance on assessing
hydromorphological quality, this document has considerably wider scope for other applications. 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,
while recognizing the important influence of hydromorphology on plant and animal ecology, no attempt
