Restoration of rivers and floodplains needs to be carried out based on the best scientific knowledge available. At the same time, restoration projects provide the great opportunity to link basic research with application for the benefit of both. In this short essay, I discuss four selected aspects that are scientifically challenging and highly relevant for restoration: (i) setting restoration priorities and need of reference systems, (ii) understanding the link between environmental heterogeneity, biodiversity, and ecosystem processes, (iii) focus on refugia for maintaining ecosystem resilience, and (iv) the potential role of ecosystem services in guiding restoration projects.
