Abstract
In the study the potential impact of climate change on river runoff in the upper Hron River, V´ah River, and Laborec River basin was evaluated using the Hron conceptual spatially-lumped rainfall-runoff model, which was driven by regional circulation models of atmosphere. The rainfall-runoff model was calibrated with data from the 1981-1995 period and validated with data from the 1996-2010 period. Changes in climate variables in the future were expressed by three different regional climate change projections: KNMI, MPI and ALADIN-Climate for the period 1961-2100. Changes in the seasonal runoff distribution were evaluated by a comparison of the simulated long-term mean monthly discharges in the river basin outlets in future decades with the present stage.
