In light of the various anthropogenic pressures on our river systems (flood protection, navigation, recreational fisheries) and current legal requirements (European Water Framework Directive), the need for integrative evaluation tools has become increasingly apparent. The so-called habitat modeling approach addresses these integrative efforts to quantify the changing environment for target species (fish, macro-invertebrates), taking into account hydrological and/or morphological changes. Over the course of extensive monitoring on the Danube east of Vienna this specific evaluation tool has been adapted and improved to allow the assessment of river engineering measures in future, especially before their implementation and to determine their potential impacts on the ecological conditions.
