Abstract: Reservoir sedimentation is a major issue for dam managers and one of the most characteristic off-site effects of soil erosion combined with the stream sediment processes. In this study, we simulate and analyze the sedimentation rates, due to soil erosion and sediment transport, of the Rio di Pusteria hydropower dam in South Tyrol (Italian Alps). The study period is between two consecutive sediment flushing operations, in June 2014 and May 2019. High-resolution bathymetric analyses before and after the sediment flushings enabled the determination of the aggregated sediment in the reservoir, during this period. The GIS version of the Soil and Water Assessment Tool (ArcSWAT) was used to simulate the hydromorphological processes and calculate the sedimentation rates of the Rio di Pusteria reservoir.
