Proportion of classified water bodies in different RBDs affected by hydromorphological pressures, for rivers and lakes (left panel) and for coastal and transitional waters (right panel)
See the EEA ETC/ICM technical report for more details and the methodology used for assessing pressures (EEA ETC/ICM, 2012a).
A water body is considered to be affected by hydromorphological pressures if it is reported with any of the aggregated pressure types 'Water abstraction', 'Water flow regulations and morphological alterations of surface water', 'River management', 'Transitional and coastal water management', 'Other morphological alterations' and/or any of the corresponding disaggregated pressure types.
The coastal waters of the Baltic have a low proportion of water bodies affected by hydromorphology pressures, except for Estonia, which reported more than half of its coastal water bodies as having hydromorphological pressures. This is an example of inaccurate reporting: Estonia has misinterpreted the pressure category 'Transitional and coastal water management'; the Estonian RBMPs do not indicate hydromorphology as a major coastal water pressure.
