The Belgian authorities requested the activation of the CEMS Rapid Mapping Component on the 14 th July to map the ongoing floods ( EMSR518 Mapping Website, EMSR518 Activation Viewer). These images will be used to perform a damage assessment.įlood delineation map in Duisburg, Germany (Copernicus EMS © 2021 EU) Increased areal visibility from weather conditions will allow acquisitions of optical imagery to be attempted for the 17 th. Monitoring products will follow up on the 16 th. Additional products were delivered on 16 July (based on a satellite image acquired on the 15th) showing substantial flooding. These include the towns of Hagen, Altena, Erkrath und Düsseldorf, and areas along the rivers Düssel/Nördliche Düssel, Rur, Erft, Agger and Sieg.Ī first flood map was produced on 14 July over the Rhine River, based on a satellite image acquired on the same day, but in which no impact of flooding was detected. The German authorised user has asked CEMS to monitor other towns and rivers reported as already affected or at very high risk. In Germany, the extension of the floods in six areas is currently being analysed in the south-east of the country: Moselle, Ahr, Pruem and Kyll rivers. These early images informed ensuing activations by the CEMS Rapid Mapping component based on the EFAS forecasts for areas in Belgium, Netherlands, Germany, Switzerland and France. As a flood peak was foreseen on 16 July for segments of other rivers, CEMS preemptively acquired satellite images of the vulnerable area through Pre-Tasking on 14 July.
On 13 July, the CEMS Rapid Mapping component was activated to map the ongoing floods in parts of Western Germany ( EMSR517 Mapping Website, EMSR517 Activation Viewer). Providing early and current maps of flooded areas
The first EFAS notifications were sent to the relevant national authorities starting on 10 July and, with the continuously updated forecasts, more than 25 notifications were sent for specific regions of the Rhine and Meuse River basins in the following days until 14 July.įigure: EFAS flood forecast from 00:00 UTC The magnitude of the floods forecasted for the Rhine River basin increased significantly in this period.
Subsequent forecasts also indicated a high risk of flooding for the Meuse River basin, affecting Belgium. On 9 and 10 July, flood forecasts by the European Flood Awareness System (EFAS) of the Copernicus Emergency Management Service indicated a high probability of flooding for the Rhine River basin, affecting Switzerland and Germany.
