Description
Activation date: 2017-12-06
Event type: Flood
Activation reason:
The scope of the service request was to generate reference information, concerning flood events that occurred from July 25 to July 27 2017, within the Hildesheim district of the Lower Saxony State of Germany. General Reference content and Land Use/Cover products were produced along with flood specific products:The observed flood extentThe maximum flood extent Estimated Maximum Flood ExtentThe observed flood extent product was generated by appropriate processing of relevant SAR imagery during and after the flood event. A classification algorithm confirmed by a semi-automatic technique of thresholding was applied on pre-processed SAR images to detect temporal changes between pre, peak-and post flood extents.The maximum flood extent was determined using the Maximum Water depth isolines. These were derived on the basis of the observed flood extent and through integrating water level estimations considering the Topographic Wetness Index levels.
