Fig. 10.7 Changes in mean seasonal and annual discharges projected for some rivers in Romania
for the period 2021–2050 relative to the period 1961–1990, based on hydrological simulations under
the A1B climate change scenario (based on the data from [167])
Within the project CLIMHYDEX, the climate change impacts on extreme flow
were estimated in two medium-sized basins in Romania: Cris , ul Alb (in the western part of Romania) and Bârlad (in the eastern part) (Fig. 10.1). The hydrological
simulations were made (using CONSUL and NOAH models) for two future periods
2021–2050 (Scenario S1) and 2071–2100 (Scenario S2). They were compared with
the simulations made for the reference period 1976–2005 (Scenario S0), under climate scenarios generated in the CLIMHYDEX Project (8 GCMs have been used,
by considering three greenhouse emission scenarios: A1B and E1 for ENSEMBLES
GCMs, and RCP4.5 for CMIP5 GCMs) [170].
For the Cris , ul Alb River basin, the results indicated a general increase of the
frequency of flash flood events in the future periods, more pronounced for the second
