The regulation of discharge and the retention of sediments in reservoirs disturb the natural water dynamics in residual flow stretches below reservoirs. However, a dynamic river morphology as well as near-natural hydrological hydrographs are fundamental prerequisites for the emergence and conservation of an intact river ecosystem. Regular sediment augmentation and the generation of artificial floods can be used to enrich the habitat mosaic of the river and thus ecologically en- hance the affected reaches in the long term. The project investigates the ecomorphological effectiveness of artificial sediment augmentation. Previous studies have already provided optimization potential for the type and geometric arrangement of sediment augmentation...
