ABSTRACT
Last version of climate change scenarios, the IPCC’s fifth report (AR5), predicts an increase in temperatures and a reduction in precipitation to the Southern Europe. Results from two Global Climate Models (HadGEM2-ES and MPI-ESM-MR) and four Representative Concentration Pathways (RCP: 2.6, 4.5, 6.0 and 8.5) scenarios are used to asses the impact of climate change on water resources and evaluate changes in droughts in the Upper Jucar River Basin (UJRB), Spain (Fig. 1), which is an example o the Mediterranean Climate. This catchment has a strategic relevance in the water resources management of the Jucar River Basin, due to it generates the natural water resources that can be stored in the major reservoirs of this River Basin, Alarcón and Contreras. These reservoirs supply of water to 1.25 million persons and 150.000 ha of irrigated land (Ferrer et al. 2012).
