period 2071–2100 (greater than 20%), and especially the increase (by 30–40%) in
the frequency of severe flash flood events. In the case of the Bârlad River basin, a
general increase of the flash floods frequency was estimated in the upper part of the
catchment, and a decrease in the middle and lower basin, for both future periods
relative to the reference period [144].
In Bârlad River basin, the scenarios S1 and S2 indicated an increase of the monthly
maximum discharges (multiannual averages) during the winter, spring and summer
months (with a significant increase in January and February), and a decrease in the
autumn months. Regarding the monthly minimum discharges (multiannual averages),
an increase was identified in the late winter, early spring and in the summer months,
and a decrease in the rest of the year, more pronounced during October–December
(Fig. 10.8a). In the future periods (scenarios S1 and S2) compared to the reference
period (S0), the simulations indicated for the annual maximum discharges a positive
trend (of maximum 15 and 30% respectively) in the upper and lower part of the
watershed, and a negative trend in the middle part (of maximum −5 and −15%
respectively). Regarding the annual minimum discharges, the simulations showed
a decrease of maximum −5 and −15% respectively, for the whole watershed [144,
165, 166].
In Cris , ul Alb River basin, the analysis of monthly maximum discharges (multiannual averages) showed, for scenarios S1 and S2 relative to S0 scenario, an increase
during the winter, spring and summer months, more pronounced from May to August
and a decrease in the autumn months. Concerning the multiannual averages of the
monthly minimum discharges, an increase was detected in the late winter, early
spring as well as in the summer months, and a decrease in the rest of the year, more
significant during October–December (Fig. 10.8b).
