Effectiveness of Sentinel-1 and Sentinel-2 for Flood Detection Assessment in Europe [PDF]

Natural Hazards and Earth System Sciences, 2022
Abstract. Inundation is one of the major natural hazards in Europe. The evaluation of the flood hazard and risk is not straightforward mainly due to the monitoring system that is poor or not uniformly distributed in the territory. The ESA Earth Observation Program, including a series of satellites, Sentinels, for the operative observation of the ...
