Activation date: 2020-02-17 <br>
Event type: Flood <br>
<br>
Activation reason: <br>
The CEMS Risk and Recovery Standard has been activated on behalf of the Ministry of Environment of the state of Brandenburg with the objective of assessing a flood event casued by heavy rainfall that hit the area of Rhin-Havelluch, District Oberhavel in Brandenburg (Germany) in June 2017. The peak of the precipitations occurred between the 29th and 30th June 2017. However, rainy days occurred during the next weeks, leading to the permanence of flooded areas until August 2017.The products generated in the framework of this activation aim at illustrating the evolution of the flood extent and at providing a quantification of affected urban areas, infrastructure and agricultural lands.Proposed solution and resultsFlood extent monitoring from Sentinel-1 acquisitions (30.06.2017-15.08.2017) within AOI01-Kremmen and AOI02-OranienburgModelled flood extent and water depth during the first week after the peak of the precipitation.Maximum water depth: 0.07-0.7mMaximum flood extent: AOI01: 12543.3 ha, AOI02: 7164.0 ha.Examples of maximum water extent and maximum water depth are shown in the following figures. Impact assessment based on the modelled maximum flood extent.Detailed damage assessment based on the visual interpretation of two VHR post-event optical images (both aquired on 20.07.2017) (examples of possible and moderate damaged buildings are shown in the following figures, respectively).  <br>
