Project summary

Edit project overview to modify the project summary.


The Aurino river is a typical Alpine watercourse (basin Area 630 km2, average discharge in summer 30-50 m3/s) affected in the past by gravel extraction, construction of bank defences along part of its course and a major reduction of sediment load from upstream, due to weirs and other protection measures in most tributaries. This determined channel incision, reduction of riverbed width, alteration of morphological structures and dynamics and as a consequence reduced connection with the floodplain, lowering of the groundwater level and loss of riparian habitats (especially hygrophilic riparian forests of Alnus incana). A major effect was also a reduced flood retention capacity, and its recovery by reverting the incision process was one of the main drivers, together with biodiversity increase, to implement a catchment scale restoration scheme. This has been carried out, step by step, for more than a decade and further measures are foreseen.
