DIN EN 15843:2010-05 EN 15843:2010 (E) 4 Introduction This European Standard will enable broad comparisons to be made of river hydromorphological modifications throughout Europe (e.g. for reporting by the European Environment Agency). The assessment of ri
30、ver “quality“ in Europe has evolved over the past 20 years. From its original focus on organic pollution it now relies on methods for analysing a range of chemical and biological attributes. More recently, several European countries have developed systems for evaluating the hydromorphological featur
31、es of rivers. The EC Water Framework Directive (WFD) has reinforced the need for this broader view of river “quality“ through its requirement for determining “ecological status“ based on macrophytes, phytobenthos, invertebrates and fish. The Directive also requires that hydromorphological and physic
32、o-chemical conditions should be suitable for supporting biological communities, although hydromorphology is only classified at high status. EN 14614, Water Quality Guidance standard for assessing the hydromorphological features of rivers describes a protocol for field survey and feature recording, w
33、hereas 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 h
34、ydromorphological 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 clas
35、sification 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 restoratio
36、n work. DIN EN 15843:2010-05 EN 15843:2010 (E) 5 1 Scope 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
37、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 hy
38、dromorphological 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 character
39、izing 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. 2 Normative
