Flood in Bulgaria (2022-11-30)

<br/> Activation date: 2022-11-30 <br/> Event type: Flood <br/> <br/> Activation reason: <br/> The CEMS Risk and Recovery Standard has been activated for the analysis of the flood occurred in September 2022 in Bulgaria, in the villages of Bogdan and Karavelovo, in Karlovo Municipality.From the 2nd of September 2022, torrential rainfalls caused rivers and streams to overflow flooding several villages in Plovdiv Province including Bogdan, Rozino, Karavelovo, Stoletovo, Pesnopoi and Trilistnik and the flooding reached a depth from 1.5m to 2m in some areas.Local media reported that the entire village of Bogdan was under water at one point after an embankment along the Stryama River failed. At least 200 homes across the province have been damaged or destroyed. Damage to infrastructures left the area without electricity and drinking water. Bridges and roads were also destroyed leaving some villages isolated. Military helicopters were used to deliver relief supplies and carry out the rescue of people. In Karavelovo and Bogdan, it was reported that 36 people were saved by boats and by various alpine techniques.A hydraulic modelling approach has been adopted to provide the temporal analysis of the occurred flood event (P06 product) in terms of maximum flood extent, maximum water depth, and flood temporal evolution estimated during the period 2nd September 2022 &ndash; 5th September 2022. The model has been calibrated using the flood footprint retrieved from a Sentinel-2 image acquired on 5th September 2022 (31.3 ha), where flood traces were observed and digitized through visual interpretation.The maximum flood extent retrieved from the hydraulic modelling is 840.4 ha in AOI01. The maximum water depth has been evaluated mostly within the range 0.5-1.4 m.The Impact assessment analyses on assets and population has been performed based on the available reference data as provided through the P02-Reference Dataset product, the GlobeLand30 dataset, and the population information provided by the WorldPop dataset. The product has been delivered by reporting, in tabular form, the impact of the maximum flood extent provided by the P06 product. <br/> <br/>
