    Abstract: The avalanche situation of Siglufjörður in northern Iceland is unique because the residential area is located directly at the base of several large avalanche paths. Due to the topographical situation, large deflecting or catching dams cannot be constructed without the removal of buildings except for the southernmost part of the town. Therefore up to 8.4 km of supporting structures in combination with small catching dams were proposed as protection measures for the central and northern part of the town. The main challenges for the application of snow supporting structures are the deep and heavy snowpack, ir-regular snow depths, rockfall, difficult ground conditions, corrosion problems, formation of large cornices and lack of experienced construction companies.
