Abstract This paper presents GIS and Remote Sensing applications to produce large scale maps on riverine landscapes and their ecomorphological quality. The overlay of the map of the planned hydropower plant "Novo Virje" in the Drava River (Croatia) exemplifies the potential of this method, in combination with in situ investigations, to show the expected destruction of riverine habitats and flood plains. This publication is part of the research topics of the International Association for Danube Research (IAD).
