Abstract: Since about 100 years the Federal Service for Torrent and Avalanche Control is existing in Austria. The Service is responsible not only for designing and erecting avalanche defense systems but also for providing avalanche hazard maps (see below). Today snow bridges (Fig. 1) or snow fences are used for the most part to prevent avalanches in Austria (costs about 3 - 4 Mio AS per ha). To reduce these costs new methods were applied in the last years, especially the foundation by blast bolt (Dragosits, 1987). If supporting structures in the starting zones are still to expensive defense systems are erected in the run-out-zones (avalanche breaking cones, deflecting walls, snow sheds ... ).
