Climate change scenarios for the Czech Republic indicate the increase in frequency and volume of the deficit discharges (defined as the volume under given threshold). The Czech water management legislation considers a number of protected areas potentially suitable for construction of reservoirs for flood protection and/or improving the water balance in the drought periods. In present study we use hydrological modelling to quantify the volume of the deficit discharges as projected by an ensemble of transient regional climate model (RCM) simulations. Derived deficits are subsequently compared to the potential volume of the considered reservoirs. It is concluded that for many RCM simulations the deficits are significantly larger than the available volume of water in the reservoirs, therefore different adaptation measures should be considered also. The uncertainty is, however, large.
