Abstract: | The study was performed on the ski resort Krvavec, which is one of the most frequented ski resorts in Slovenia. The ski slopes
serve as pastures for cattle during summer time and range from 1500 to 2000 m a.s.l., which is at or above the upper timberline.
To offer a longer ski season and to profit snow better (either natural or artificial one) the slopes have been levelled and
consequently the soil profile has been changed. Such altered soil profile characteristics strongly impact hydrological functions
of soils.
To study these impacts, five plots (20 × 20 m) have been chosen on the slopes with a different history: pasture without any
amelioration work, a patch of forest in the ski resort without any ameliorations, and three plots with different intensity
of amelioration.
Dynamics of soil water content on each plot has been determined by measuring soil water content in-situ with portable TDR
system during several days after long lasting heavy rains. Statistically significant differences were shown in soil water
content between the plots after the rain, although some differences between plots have disappeared in the following days. |
