This document provides guidance on characterizing the hydromorphology of TraC waters. Its main aim is to improve the comparability of hydromorphological survey methods, data processing, and the interpretation and presentation of results. In a general sense, transitional waters (e. g. estuaries, fjords, some lagoons) are neither fully open coastal systems nor enclosed or flowing freshwater areas (for the WFD definition, see Clause 2.). Their boundaries may be defined by hydromorphological features and discontinuities, by salinity, or by any other hydrographic feature (e. g. water depth and tidal regime). The term "coastal waters" has been defined for various legal and political purposes (e. g. see clause 2) but in this hydromorphological standard they are defined as waters characterized by coastal features and influenced by coastal processes. This European Standard is designed to: a) support environmental and conservation agencies in meeting monitoring requirements of the WFD and MSFD; b) generate data sets appropriate for monitoring and reporting on the condition of Natura 2000 sites designated under the Habitats Directive and the Birds Directive; c) provide information supporting other environmental reporting requirements (e. g. in relation to biodiversity or environmental impact assessment); d) support management and restoration initiatives. This European Standard: e) defines the term ‘hydromorphology’ and other terms relating to the physical characteristics of TraC waters and their hydrological regimes; f) lists essential features and processes of TraC waters that should be characterized as part of a hydromorphological survey and used for determining hydromorphological condition; g) identifies and defines the main pressures affecting European TraC waters; h) gives guidance on strategies for collecting and presenting hydromorphological data depending on the resources available and the anticipated use of the assessment; i) provides guidance on data quality assurance. This European Standard does not deal with biological assessments in TraC waters such as the presence or absence of individual species or community composition, nor does it attempt to link specific hydromorphological features with their associated biological communities. However, it is relevant where plants or other organisms form significant structural elements of the habitat (e. g. saltmarshes, biogenic reefs).
