 This research paper presents a novel approach to automatically detect and extract flooded areas and surface waters using sentinel 1 amplitude data. The proposed methodology was tested on three different sites affected by recent flooding events and achieved high accuracy rates of up to 98%. This demonstrates the potential of the proposed methodology as a reliable tool for fast and accurate flood and surface water mapping.
