How can ecological status be summarized for an operational Pressures/States model ?

TL;DRAbstract

The Water Framework Directive implementation requires models involving environmental indicators to report water state, to describe anthropogenic pressures, and to assess impacts of restoration measures. These indicators are built from observations, modelling results, expertises and processes hypothesis... They are routinely used in information system by stakeholders and managers. Our work, funded by Rhone-Méditerranée and Corse Water Agency, aims to develop new Pressure/State models to help the choice of restoration measures. In this presentation, we describe the first steps of the approach and focus on the specification of a water quality indicator taking account availability and quality of information. In France, water quality information is providing by different networks. These networks can be permanent or temporary and managed at different levels. Two national monitoring networks are managed by the French water agencies for European reporting and monitoring water quality of French
