EN 14614:2004 (E) 4 Introduction Historically, many countries in Europe have assessed river quality simply in terms of the chemical or pollution status of the water flowing in river channels. A more comprehensive view of river habitat
20、s is needed, however, to answer pressing ecological questions such as those arising from the EC Water Framework Directive (WFD) (Commission of the European Communities, 2000) and the EC Habitats Directive, to underpin the International Convention on Biodiversity, or to assess proposed river engineer
21、ing schemes and other catchment developments. In most European countries there are now pressures from statutory and voluntary environment and conservation agencies to see rivers returned to a more natural condition. This implies a need to evaluate areas deserving protection and those requiring rehab
22、ilitation, and to encourage better management of river systems throughout Europe. EN 14614:2004 (E) 5 1 Scope This document provides guidance on the features to be recorded when characterising and assessing the hydromorphology of rivers. It is based on methods developed, tested, and compared in Euro
23、pe. Its main aim is to improve the comparability of hydromorphological survey methods, data processing, interpretation and presentation of results. Whilst it has particular importance in relation to the reporting requirements of the WFD, it also has considerably wider scope for other applications. A
24、lthough hydromorphology is dependent on hydrology and underlying geology, this standard is focused on the structural features of rivers and on river continuity. In addition, whilst recognising the important influence of hydromorphology on plant and animal ecology and, conversely, the influence of pl
