The aim of this study is to estimate impacts of global climate change on water yield and runoff timing in a small alpine catchment (basin of the Skalnaté pleso (lake), the High Tatras, Slovakia). To predict the hydrological regime during the period of 2071–2100, the outputs from two general circulation models, HadAM3H and ECHAM4/OPYC3, were downscaled by a regional climate model, RCAO, which ran scenarios A2 and B2 for each model.
Simulated data of monthly air temperature and precipitation were compared with the data observed in the period of 1961–2005.
