Abstract

In a 2-year research project the designation of heavily modified water bodies according to the European Water Framework Directive (WFD) has been examined on the basis of four case studies, namely the river basin districts of the Elbe, Lahn, Seefelder Aach and Dhuenn, in order to concretise the WFD requirements in Germany. In particular, the purpose of these case studies was to actively support the CIS working group 2.2 ''Heavily Modified Water Bodies'' during the development of the European guidance document for the identification and designation of heavily and artificial water bodies. The support was given by cooperating together with the international subgroups ''Navigation'' and ''Hydro Power Generation'' and by participating at European workshops on that topic. The study focuses on the development and testing of criteria to identify significant physical alterations, scenario development of measures to reach the good ecological status and their evaluation within an economic analysis. Furthermore, the identification of the conditions to achieve by establishing criteria for heavily modified water bodies with special emphasis on maximum and good ecological potential has been elaborated. Additional results refer to the scales that should be applied for the identification of water bodies, testing of criteria, evaluating ecological status and ecological potential and linking the IMPRESS and HMWB guidance documents produced by the CIS working groups.
