Methods database (workpackage 2.2)

This database contains information about the national assessment methods used to classify the ecological status of rivers, lakes, coastal and transitional waters. Member States of the European Union apply these methods in their monitoring programmes according to the EU Water Framework Directive.

The information in this database was provided by the Member States through a questionnaire survey and collated within workpackage 2.2.
