The area affected by the floods that took place during 1st - 2nd of June 2019 is located in the southern part of Alba county, where significant precipitation had fallen in a very short time. The Pianu, Cioara si Rachita catchment areas are not monitored either from a hydrological or from a rainfall point of view. The rapid floods formed on the Pianu, Cioara and Răchita rivers with their cadastred and non-cadastred tributaries caused great damage in 4 municipalities (Pianu, Săsciori, Săliştea and Şibot): there were flows and extraordinary levels on Răchita and Cioara rivers. The largest damages were recorded in Pianu and Săsciori municipalities, whereas the lowest ones were enlisted at Șibot. The greatest destruction was made by Răchita river, that is 5 km long, followed by Pianu River. The flash floods affected households, institutions, county roads, street roads, forest roads, water and sewage networks, sewage plants, electricity and gas networks, telephony networks, cultural centres, shops, bridges, footbridges, pedestrian bridges, and agricultural crops. The total amount of the damages caused by flash floods on June 1st, 2019 was estimated at around 44.674,864 thousand lei, almost half of which were recorded in the radius of Pianu municipality. There were no human casualties, instead the flash-flood on Cioara river caught in and drowned 213 small animals. On Răchita river there was recorded a historical flash-flood, with a probability of occurrence of once every 200 years, whereas the historical flash-flood recorded on Cioara river (upstream the confluence with Freman river) had a probability of occurrence of once every 130 years; on Pianu river (at Pianu de Sus), the probability of occurrence was once every 35 years.
