The development of the European water policy has been in a continuous improvement process during the last fifty years. The adoption of Water Framework Directive (WFD) enabled the consolidation of a fragmented policy to comprehensive approach with a focus on sustainability. The floods Directive was developed as acomplement to the WFD and promoted their integration. However, several opportunities have been identified in the implementation and in achieving integration. This paper identifies integration gaps faced by practitionersand develops an assessment framework which can be used by diverse stakeholders from policy makers to water users to understand the degree of integration in a systematic way. Indicators within the framework can shed light on the progress and optimize the development of action plans to address integration gaps and achieveefficiency gains. Although not a remedy for the complex challenges, establishing measuring systems is a first step to ensure integration of current and future directives.
