Water quality - Guidance standard on determining the degree of modification of river hydromorphology

Le présent document fournit des recommandations d'évaluation des modifications de caractéristiques hydromorphologiques des rivières décrites dans la norme NF EN 14614. Il 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. Il évalue principalement "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 de leurs caractéristiques. Le présent document s'applique également à la planification de l'occupation des sols, à la conservation de la nature, à l'évaluation de l'impact sur l'environnement, à la gestion des bassins de rivières, à l'évaluation des risques d'inondation (par exemple : la Directive CE "Inondations") et à l'établissement de cibles dans le travail de restauration des rivières.

ZOOM ON ... the Requirements department

To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:

mandatory clauses to satisfy,
non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document "ISO/IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents" as well as on a constantly enriched list of verbal forms.

With Requirements, quickly access the main part of the normative text!

The Redline + service - standards comparator allows you to easily and simply identify major changes between the current standard and its last canceled version.

At a glance, you will be able to identify the additions, deletions or modifications to a text, table, figure and formula.
