Abstract: Experiments were done on the Stubai glacier area about 3000 m asl during July 1992. The. experiments lasted one week. In order to be independent on the actual weather conditions natural melting and/or precipitation rates (rain on snow) were simulated. Flepacked homogenous snow of a more or less uniform grain size of approximately 0.6 mm was used. Depending on the initial water saturation and the water input rate at the snow surface shock fronts were formed. Using a new measuring method it was possible to register continuously the liquid content directly within the snowpack. This opened the possibility to record shock fronts in time and space with a high resolution. Furthermore basic experimental studies with dye-tracers were done in order to get insight into the qualitative behaviour of transport and adsorption of different tracers.
