Water quality - Guidance standard on determining the degree of modification of lake hydromorphology
This European Standard provides guidance on determining the degree of modification of lake hydromorphological features described in EN 16039. It enables consistent comparisons of hydromorphology between lakes within a country and between different countries in Europe, providing a method for broad based characterization across a wide spectrum of hydromorphological modification. Its primary aim is to assess ‘departure from naturalness’ for a given type of lake as a result of human pressures, and it suggests suitable sources of information that may contribute to characterizing the degree of modification of hydromorphological features. For wholly artificial lakes or reservoirs formed by damming rivers the aim is to assess the extent to which processes approximate to those in comparable natural water bodies. However, this standard does not replace methods that have been developed within particular countries for local assessment and reporting. Decisions on management for individual lakes require expert local knowledge and vary according to lake type.

Qualité de l'eau - Préconisations pour la détermination du degré de modification des caractéristiques hydromorphologiques des lacs
La présente Norme européenne donne des préconisations sur la détermination du degré de modification des caractéristiques hydromorphologiques des lacs décrites dans l'EN 16039. Elle permet des comparaisons uniformes de l'hydromorphologie entre différents lacs dans un pays, et entre différents pays européens, en offrant une méthode de caractérisation à large échelle à travers un vaste éventail de modifications hydromorphologiques. Elle a pour but premier d'évaluer « l'écart par rapport au caractère naturel » pour un type de lac donné par suite de pressions anthropiques, et elle suggère des sources d'informations pertinentes pouvant contribuer à caractériser le degré de modification des caractéristiques hydromorphologiques. Dans le cas de lacs entièrement artificiels ou de réservoirs créés en construisant un barrage sur un cours d'eau, le but est d'évaluer dans quelle mesure les processus se rapprochent de ceux existant dans des masses d'eau naturelles comparables. La présente norme ne remplace toutefois pas les méthodes locales d'évaluation et de rapportage qui ont été élaborées dans certains pays. Les décisions concernant la gestion de lacs individuels exigent une expertise locale, et varient suivant le type de lac. L'évaluation des conditions hydromorphologiques pour les besoins de la DCE (qui soutiennent les éléments de qualité biologique) reste de la compétence des différents États membres.
Kakovost vode - Navodilo za določevanje stopnje spremenjenosti hidromorfoloških značilnosti jezer
Ta evropski standard podaja navodilo za določevanje stopnje spremenjenosti hidromorfoloških značilnosti jezer, opisanih v standardu EN 16039. Omogoča usklajene primerjave hidromorfologije med jezeri v državi in med različnimi evropskimi državami, za kar zagotavlja metodo za vsesplošno karakterizacijo širokega spektra hidromorfoloških sprememb. Njegov osnovni namen je ocena »odmika od naravnosti« za dano vrsto jezera kot posledica pritiskov s strani človeka in predlaga ustrezne vire informacij, ki lahko prispevajo k karakterizaciji stopnje spremenjenosti hidromorfoloških značilnosti. Pri povsem umetnih jezerih ali vodnih zbiralnikih, nastalih z zajezitvijo rek, je cilj oceniti obseg, v katerem se procesi približajo procesom v primerljivih naravnih vodnih telesih. Vendar pa ta standard ne nadomešča metod, razvitih v posameznih državah za namene lokalne ocene in poročanja. Za odločitve glede upravljanja za posamezna jezera je potrebno lokalno strokovno znanje, ki se razlikuje glede na vrsto jezera.
