ABSTRACT. - Extreme Precipitation Events in the Mountain and sub-Mountain Areas of the Făgăraş Mountains in June 10 to 11, 2011. In the last decades, permanent residencies and temporary tourist dwellings have been built in the sub-mountain area of the Făgăraş Mountains, mainly in the proximity of the Olt River, being exposed to significant floods during extreme precipitation events. The studied case started with a decade of both thermal and rainfall extreme events. Major floods occurred in the night of 10/11 June, generated by significant precipitation amounts, setting a new historical record, of 236.6 mm/24 h. Flood level was exceeded on 3 tributaries (Cārţişoara, Arpaşu Mare, Arpăşel), damages were reported at about 100 houses, 250 persons were evacuated, tens of ha were flooded, several bridges were destroyed. The meteorological case analysis covers the mountain and sub-mountain area, and it is based on data retrieved from meteorological stations, global models ECMWF and ARPEGE, ALADIN mesoscale model and satellite images.
