Status is good as there are no coastal water bodies subject to the impact of "elevated temperatures" or "saline intrusions or alteration" based on the analysis of pressures and impacts carried out in accordance with Art. 5 of the Water Framework Directive

There are no data and methodologies for assessing the impacts of physical, chemical and biological habitats of the water column and the seabed including the associated communities and functional groups. In addition, no data are available to identify activities that cause impacts "elevated temperatures". It is necessary to develop a standard methodology on a national scale for the assessment of pressures and impacts due to changes in physiographic and hydrological processes to be used in the second cycle of the Management Plans District (Dec 2015). To this end two lines of research objectives have been identified as: 1) Description of the quantitative level of pressure due to change of the thermal regime or salinity using parameters: volume, flow, dispersion. The tools for this study are models of hydrodynamics and coastal oceanography (MyOcean) and monitoring. 2) Description of the quantitative level of impact due to changes in the thermal regime and salinity through the study of the alteration of community (eg species composition) and ecosystem functions. Possible tools: modeling, mapping of benthic habitats (EuSeaMap) and monitoring.
