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) subject in the past to a radical channalization (riparap) which reduced significantly the width of the riverbed and the morphological structures and dynamics and which caused a general riverbed lowering and the lost of the connection with the floodplain. In the same time the groundwater lowering caused a loss of the hygrophilous riparian forests (Alnus incana). The riverbed widening of Aurino river in Gatzaue was planned mainly to increase the biodiversity and to invert the riverbed and grounwater lowering process.
