Abstract

The article deals with an assessment of the impact of climate change on the hydropower potential in the selected river basins in Slovakia. The basic indicator of the potential for water energy utilization is the calculation of the so called hydropower potential (HPP). Changed climate conditions characterized in particular by the changes in precipitation, potential evapotranspiration and air temperature in the future decades were predicted according to the latest outputs of two regional climate change models KNMI and MPI and the A1B emission scenario. To specify changes in long-term mean monthly runoff in comparison with the reference period 1981-2010 and future time horizons, we used the physically-based rainfall-runoff WetSpa model. Based on the climate change projections of two climate change scenarios, the results agree that changes in climate and water use will lead to decreases in water resources especially in hydropower potential.
