Title:	Construction of a snow retention basin in an Alpine sagging mass / Errichtung eines Beschneiungsteiches in einer alpinen Sackungsmasse
Abstract:	This contribution deals with the construction of a snow retention basin (for manufacturing snow) in the ski region Shuttleberg Flachauwinkl-Kleinarl/Salzburg in a sagging mass movement. In the design stage it was not known whether deformations of the mass movement have to be expected and if so to what amount. Therefore probable scenarios of deformation rates of the mass movement were considered in the design and measurement equipment have been installed in order to observe the behaviour of the construction. First results of the observational system will be presented and discussed after a life time of about two years of the construction. Im vorliegenden Beitrag wird über die Errichtung eines Beschneiungsteiches im Skigebiet Shuttleberg Flachauwinkl-Kleinarl im Bundesland Salzburg berichtet, der in einer großräumigen aktiven Sackungsmasse errichtet wurde. Da im Zuge der Planung/Bauausführung noch nicht bekannt war, ob und in welcher Größenordnung die Sackungsmasse tatsächlich noch Bewegungen aufweist, wurde die Projektierung auf Basis realitätsnaher Szenarien hinsichtlich möglicher Hangbewegungen durchgeführt und entsprechende (messtechnische) Überwachungsmaßnahmen vorgesehen. Nach einer mittlerweile ca. zweijährigen Beobachtungszeit werden erste Ergebnisse der messtechnischen Beobachtung präsentiert und diskutiert.
