The Water Framework DirectiveDirective 2000/60/EC to establish a framework for water policy and management in Europe requires the intercalibration of assessment methods to set consistent and comparable standards for rivers, lakes and coastal waters across Europe.
Good ecological status should be comparable between countries. In other words: Monitoring schemes need to follow the same standards and should lead to comparable results.
Intercalibration will determine the colour-coded presentation of the state of the aquatic environment and of the river basin management plansOutlines restoration goals to be achieved and the measures required in Europe.
Ultimately, intercalibration will determine the investment in restorationActivity to improve the status of degraded waters, be it waste water treatment or structural improvements of European aquatic ecosystems.
