2019 Natural Hazards and Earth System Sciences  
Hydraulic simulation revealed that water reached a depth of 3 m at some points, and modelled water depths highly correlate (R2=0.91) with in situ after-event measurements.  ...  Modelled flooding extent is in close agreement with the observed extension by the Copernicus Emergency Management Service, based on Sentinel-1 imagery, and both far exceed the extension for a 500-year  ...  This small Mediterranean catchment is not gauged by any local water agency.  ...
