The achievement: interoperable web based availability of all data sets via viewing and download services. Directive 2000/60/EC of the European Parliament and of the Council establishing a framework for the Community action in the field of water policy or, in short, the EU Water Framework Directive (or even shorter the WFD) is the basis of a comprehensive water protection in Europa to get polluted waters clean again, and ensure clean waters are kept clean. Directive 2007/60/EC of the European Parliament and of the Council on the assessment and management of flood risks establishing a framework for Community action in the field of water policy requires river basin management plans to be developed for each river basin district in order to achieve good ecological and chemical status, and it will contribute to mitigating the effects of floods. The main target is to build up a harmonised data model for both categories of the water management focused as follows:  A centralised administration of all basis data concerning water management  Following up of water specific objects based on one data model  A concerted administration of measurements  Availability of interoperable linked data.Text/Conference Paper
