Water & River Basin Management in Europe Key facts Peter Kristensen, EEA Conceptual overview of the relation between drivers, hydromorphological pressures and habitat and flow alterations. potential based on the list in WFD Annex V. 1.1. Among others, impact of hydromorphological pressures that should be dealt in RBMPs are: • change in hydrological regime; • interruption of river and habitat continuity and disconnection of adjacent wetlands/floodplains; • change in erosion and sediment transport

Water & River Basin Management in Europe Key facts Note: The percentage is calculated against the total number of classified surface water bodies in Member States reporting. MS reporting the specific pressure or impact for that specific water category. Number of Member States reporting hydromorphological pressures or altered habitats is listed in parenthesis. Source: WISE-WFD database, 3 May 2012. In RBMPs hydromorphological pressures on surface water bodies were categorized by the Member States into main pressure groups: • Water abstraction - modifying significantly the flow regime of the water body • Water flow regulations and morphological alterations • River management • Transitional and coastal water management • Other morphological alterations, and • Other pressures (including land drainage – in transitional and coastal water bodies other • pressures were not included into the hydromorphological analysis) Percentage of classified water bodies being affected by hydromorphological pressures or having altered habitats
