ABSTRACT: A hydrological assessment of torrent catchment areas in the Alps is frequently limited for lack of reliable data about temporary snowpack reservoirs. To remedy the situation, snow depth and water equivalents are surveyed in regular intervals on a total of 15 measuring lines in the catchment area of Gradenbach creek in Upper Carinthia, at altitudes varying between 1,200 m and 2,100 m. The survey period of most of the measuring lines now extends up to 29 years. This data is now analyzed regarding changes caused by climate change. Special attention is paid to changes in the snow cover duration, snow depths, and snow water equivalents but also to the proportion of liquid and solid precipitations throughout the years. Furthermore, other data of meteorological stations located in the area are included in the analysis. These are air temperature, precipitation and global radiation. This short report gives a first insight into these evaluations.
KEYWORDS: snow hydrology, climate change, water equivalent.
